† Daphnella gracillima Tenison Woods, 1876 Teleochilus gracillimus is an extinct species of sea snail, a marine gastropod mollusk in the family Raphitomidae.

(Original description) The fusiform shell is thin, fragile and shining.

They are regularly and somewhat distantly grooved with rather broad, flat, shallow, conspicuously striate grooves, one of which is much broader just below the suture, which is distinctly canaliculate.

The protoconch is obtuse and smooth, but granulations could have been present as the slightest wear removes them.

Fossils of this marine species were found off Table Cape, Tasmania, Australia and in Eocene strata at Muddy Creek, Victoria.
