Type locality: Timb's (Timm's) Hammock, Dade Co.
Holotype: FLMNH No. 241005
Description: Liguus crenatus eburneus Simpson 1920, PBSW, 33: p. 122; LFW, frontispiece, fig. 10.
A transcription of the original description follows.
Liguus crenatus eburneus, n. subsp.
Shell rather solid, usually somewhat elongated, pure ivory white throughout, or rarely having a few faint spiral lines back of the basal part of the aperture.
The type measures: Length, 52 mm.; diameter, 26 mm.
The type was collected on Timb's Hammock, Lower Dade County, Florida. It has also been collected on the mainland from Long Key in the Lower Everglades north to Lemon City. The type is in the author's collection. It is figured in "Lower Florida Wilds," frontispiece, fig. 10.
Paratype Cat. No. 339093, U.S.N.M.

Holotype
My take on Simpson's description and type follows.
"Liguus crenatus eburneus, n. subsp."
I place eburneus as a junior synonym of elliottensis of the elliottensis group of the solidus subspecies. The varieties of this group have a white tip and parietal, and are zonated and unvariegated..
"Shell rather solid, usually somewhat elongated, pure ivory white throughout, or rarely having a few faint spiral lines back of the basal part of the aperture."
This is the entire description, and it could equally refer to elliottensis.
Shells from Timm's Hammock and Elliott's Key are not separable without locality data. I place eburneus as a junior synonym of elliottensis.



Timm's Hammock
These topotypes, collected in 1937, were part of a representative lot. I see nothing that separates them from elliottensis. Simpson's type seems to be somewhat atypical, in shape and green line expression, of a Timm's shell.
