...was talking to a teacher with greasy black hair, a hooked nose, and sallow skin
pg 126
The hook-nosed teacher looked past Quirrell's turban straight into Harry's eyes -- and a sharp, hot pain shot across the scar on Harry's forehead.
pg 126
...then Malfoy turned into the hook-nosed teacher, Snape, whose laugh became high and cold -- there was a burst of green light and Harry woke, sweating and shaking.
pg 130
His eyes were black like Hagrid's, but they had none of Hagrid's warmth. They were cold and empty and made you think of dark tunnels.
pg 136
Harry forced himself to keep looking straight into those cold eyes.
pg 138
As Gryffindors came spilling onto the field, he saw Snape land nearby, white-faced and tight-lipped --- then Harry felt a hand on his shoulder and looked up into Dumbledore's smiling face.
pg 224

There, his black robes rippling in a cold breeze, stood Severus Snape. He was a thin man with sallow skin, a hooked nose, and greasy, shoulder-length black hair, and at this moment, he was smiling in a way that told Harry he and Ron were in very deep trouble.
pg 78
Chapter 9
The Writing on the Wall
"But why not join the feast afterward?" said Snape, his black eyes glittering in the candlelight. "Why go up to that corridor?"
"Because __ because __" Harry said, his heart thumping very fast; something told him it would sound very far-fetched if he told them he had been led there by a bodiless voice no one but he could hear, "because we were tired and wanted to go to bed," he said.
"Without any supper?" said Snape, a triumphant smile flickering across his gaunt face. "I didn’t think ghosts provided food fit for living people at their parties."
"We weren’t hungry," said Ron loudly as his stomach gave a huge rumble.
Snape’s nasty smile widened.
pg 143
Chapter 7
The Boggart in the Wardrobe
Snape approached their table, stared down his hooked nose at the roots, then gave Ron an unpleasant smile from beneath his long, greasy black hair.
pg 134
Chapter 12
The Twiwizard Tournament
On Professor Sinistra's other side was the sallow-faced, hook-nosed, greasy-haired Potions master, Snape -- Harry's least favorite person at Hogwarts. Harry's loathing of Snape was matched only by Snape's hatred of him, a hatred which had, if possible, intensified last year, when Harry had helped Sirius escape right under Snape's overlarge nose -- Snape and Sirius had been enemies since their own school days.
pg 175
"Thank you, Severus," said Dumbledore firmly, and Snape went quiet, though his eyes still glinted malevolently through his curtain of greasy black hair.
pg 276
Chapter 18
The Weighing of the Wands
Snape had arrived. The Slytherins clamored to give their explanations; Snape pointed a long yellow finger at Malfoy and said, "Explain."
pg 299
Harry imagined picking up his cauldron, and sprinting to the front of the class, and bringing it down on Snape's greasy head—
pg 301
"Please, sir, I'm supposed to take Harry Potter upstairs." Snape stared down his hooked nose at Colin, whose smile faded from his eager face.
pg 301
Chapter 25
The Egg and the Eye
"A student, I daresay," said Snape. Harry could see a vein flickering horribly on Snape's greasy temple. "It has happened before. Potion ingredients have gone missing from my private store cupboard ...students attempting illicit mixtures, no doubt..."
"Reckon they were after potion ingredients, eh?" said Moody. "Not hiding anything else in your office, are you?"
Harry saw the edge of Snape's sallow face turn a nasty brick color, the vein in his temple pulsing more rapidly.
pg 471
Harry could have sworn his over-large nostrils were dilating, trying to sniff Harry out ---
pg 473
Slimy, oily, greasy-haired kid, he was," Sirius added, and Harry and Ron grinned at each other.
pg 531
Chapter 36
The Parting of the Ways
He looked slightly paler than usual, and his cold, black eyes glittered strangely.
pg 713
Chapter 4
Number 12, Grimmauld Place
In the very center of the group Harry saw the dark, greasy-haired haired head and prominent nose of his least favorite teacher at Hogwarts…
pg 76
Chapter 5
Order of the Phoenix
Screwing up her eyes each time with the same pained expression she had worn back in Harry’s bedroom, her nose swelled to a beaklike protuberance like Snape’s.
pg 85
…and as Snape swept by he looked down his hooked nose at it without comment…
pg 233
Chapter 17
Education Decree Number 24
His black eyes swept up the Gryffindor line…
pg 362
…”I suppose this is relevant?” Snape asked, his black eyes narrowed.
pg 364
Snape looked around at him, his face framed between curtains of greasy black hair.
pg 518
An ugly flush suffused Snape’s pallid face.
pg 518
Snape pulled out his wand from an inside pocket of his robes and Harry tensed in his chair, but Snape merely raised the wand to his temple and placed its tip into the greasy roots of his hair.
pg 533
Snape looked paler than usual, and angrier, though not nearly as angry as Harry was.
pg 536
Chapter 26
Seen and Unforeseen
Snape’s dark eyes bored into Harry’s.
pg 590
“Perhaps,” said Snape, his dark, cold eyes narrowing slightly…
pg 591
Chapter 28
Snape’s Worst Memory
Snape-the-teenager had a stringy, pallid look about him, like a plant kept in the dark. His hair was lank and greasy and was flopping onto the table, his hooked nose barely an inch from the surface of the parchment as he scribbled.
pgs 640-641
Round-shouldered yet angular he walked in a twitchy manner that recalled a spider, his oily hair swinging about his face.
pg 643
"You took my last bottle to interrogate Potter," he said, surveying her coolly through his greasy curtains of black hair.
pg 744

After a few seconds, they heard movement behind the door and it opened a crack. A sliver of a man could be seen looking out at them, a man with long black hair parted in curtains around a sallow face and black eyes.
pg 22
It was not until the glowing yellow light was ten feet away from them, and Harry had pulled off his Invisibility Cloak so that he could be
pg 159
seen, that he recognized, with a rush of pure loathing, the uplit hooked nose and long, black, greasy hair of Severus Snape
pg 160
Chapter 9
The Half-Blood Prince
The classroom door opened as she spoke, and Snape stepped into the corridor, his sallow face framed as ever by two curtains of greasy black hair.
pg 176
Chapter 15
The Unbreakable Vow
Trapped, with Slughorn's arm around his shoulders, Snape looked down his hooked nose at Harry, his black eyes narrowed.
pg 319
"Ten o'clock," whispered Snape, with a smile that showed his yellow teeth. "Poor Gryffindor...fourth place this year, I fear..."
pg 528
Chapter 28
Flight of the Prince
Snape's pale face, illuminated by the flaming cabin, was suffused with hatred just as it had been before he had cursed Dumbledore.
pg 604
