The Late Gatsby question

This books references a lot of other vampire media (novels, movies, even poems) and I was hoping to get a list going of all these details which readers might miss otherwise, I'll start by naming some obvious references:

In chapter 2 Nick reads Lair of the White Worm, by Bram Stoker, author of Dracula: A Norton Critical Edition, which also gets a lot of references in the book.

Characters names:
Carmilla - from Carmilla
Varney - from Varney the Vampire
Orlock - from the movie Nosferatu

And the one I liked the best:

"... a prince of something with a purplish hue and an enormous sharp nose whom we jokingly called “The Count” since he suffered from arithmomania, obsessively counting everything in sight, and whose name, if I ever knew it, I have forgotten."

- obviously a reference to the count from Sesame Street.

So, what else did you find?
