Bulimulus immaculatus C. B. Adams. 
Bulimus flavidus Henke. 
,, stramineus (pari) Guilding. 
,, immaculatus Reeve , Conch. Icon. Bui. 85. 
A slioll similar to the last, but distinguished by its yel- 
lowish.- white color and tho complete absenco of color-bands. 
It is a vory abundant shell in somo localities, particularly in 
eorno gardens at Port-of- Spain. It is found also on tho tops 
of trees in tho forests over a great part of tho island. It 
occurs in St. Vincont, Jamaica, and others of the Antilles, 
and sooms to have boon confounded by Guilding with his 
B. 8tramineu8 t which differs in tho angle of tho spire being 
groator and in other particulars. Those differences aro not 
in my opinion varietal, but probably spocific. 
Hoight 35 millimetres, diameter 1 3 millimetres. 
Bulimulus aureolus Guppy. 
Bulimus auroolus Guppy > Ann. Sp Hag. Hat. Hist. 3 sor.

This is a rare species of which I have as yet only found 
a fow oxamplos on trees at Savana Grando. It is remark- 
able for tho singularly beautiful transparent yollow color 
of tho sholl, and the brighter yollow of tho mantlo of tho 
animal. It is a shell of the same genoral character as tho 
last species, and resembles B. stramineus of Guilding. The 
epecimons found by mo havo not occurred with an expand- 
ed lip, but I am not sure whon tho shell is quite adult 
that it does not in this respect resemble the two foregoing 
species. 
Height 15 millimetres, diameter 7 millimetres.
