I've been thinking about this idea, and would like to list some examples
of some well-known Mythos stories which utilize, or feature prominently,
Monsters (rather than Gods) of the Mythos:
"The Shambler From the Stars" by Robert Bloch (Star Vampires)
"Notebook Found in a Deserted House" by Robert Bloch (Shoggoths)
"The Fire Vampires" by Donald Wandrei (Fire Vampires)
"The Tree-Men of M'Bwa" by Donald Wandrei
"The Hounds of Tindalos" by Frank Belknap Long (Hounds of Tindalos)
"The Tale of Satampra Zeiros" by Clark Ashton Smith (Formless Spawn of
Tsathoggua)
"The Vaults of Yoh-Vombis" by Clark Ashton Smith
"The Deep Ones" by James Wade )Deep Ones)
"The Church in High Street" by Ramsey Campbell (The Tomb-Herd)
"The Insects From Shaggai" by Ramsey Campbell (Insects From Shaggai or
Shans)
"The Invaders" by Henry Kuttner
"Something From Out There," "The Passing of Eric Holm" and kindred
stories by August Derleth and Mark Schorer (featuring Spawn of Cthulhu)
"Lair of the Star-Spawn" by Derleth and Schorer (Tcho-Tchos)
"From Beyond the Stars" by Richard L. Tierney (The Galactics, or
Zarrians)
"The Cyprus Shell" and The Deep-Sea Conch" by Brian Lumley (malevolent
mind-switching snails)
"Rising With Surtsey" by Brian Lumley (Gell-Ho-ians)
"The Caller of the Black" and "The Black Recalled" by Brian Lumley
(Black Blood of Yibb-Tstll)
I'm sure there are countless others, but this will serve, off to top of
the head, to illustrate my point.
