local collectors, some considering it a variety of G. arenosa, and 

 others C. carneola var. propinqua Garrett. I think it is closer to 

 carneola than arenosa, but it differs from propinqua in having no 

 violet ring and in the color of the teeth.

BY W. H. FLUCK. 



Liotia cruentata Miihlf. 



Omphalius viridulus Gmel. 



Omphalius indusii Ch. 



Livona pica Linn. 



All from Man of War Keys. The last-named species is found by 

 the dory-load, and is used as an article of food by the natives. When 

 perfect, the shell is beautifully mottled with white and black, but 

 most specimens from " the keys " are badly incrusted. The beau- 

 tiful spiral operculum is a study in itself. 



Fissuridea alternata Say. Wounta Haulover. I found about a 

 dozen in four years, the locality being, I suppose, not rocky enough 

 for them. 



Subemarginula octoradiata Gmel. Man of War Keys. 



Acmcea melanoleuca Gmel. King's Keys. A white variety. 



Guppya biolleyi Mart. Eama Key. This little island is in the 

 Bluefields lagoon, about 10 miles south of the town of Bluefields. 

 The shell was found in the yard of the Moravian Mission. 



Epiphragmothora coactiliata Fer. Weilawas Hill, near Wani, 

 Nicaragua, near where the Ulli river and Wani river meet to form 

 the Prinzapolka river. 



Bulimulus corneus Sowb. Bluefields, in the garden of the Mora- 

 vian Mission, among flags and other plants and under stones. 



Macroceramus caracasensis Rve. Bluefields. Same locality and 

 station. 



Macroceramus concisus Morelet. Weilawas Hill, Wani, Nic. 



Bifidaria sp. ? Bluefields. Numerous. Clinging to stones. Dr. 

 Ball has seen specimens, and says they much resemble B. eyriesii 

 Drouet, of Venezuela, or P. wolfii Miller, of Ecuador, adding : 

 " There are so many of these described that I don't dare attempt to 

 name it, especially as our series of these species from the tropics 

 is very incomplete."
