Triton oMorostoma, Lam.

Triton tuberosum, Lam. 



W. Indies, Mauritius, Society Is. 



Epidromus ooncinnus, Reeve. 



Philippines. 



This species, the specimens of which are absolutely identi- 

 cal with the forms from the Philippine Islands, is closely re- 

 lated to Tryon's Epidronms Swifti, from Antigua, but tlie ribs 

 are less prominent than in that species, and the general out- 

 line of the siiell is more acicular. 



Epidromus (Triton) lanceolatus, Menke. 



I give this species on the authority of Matthew Jones (Con- 

 tributions to the Natural History of the Bermudas, Trans. 

 Nova Scotia Inst.) 



Ranella crnentata, Sow. 



var. i?. Rhodostoma, Beck. 

 R. Thomse, D'Orb. 



St. Thomas, Mauritius, Philippines. 



Fasoiolaria distans, Lam. 



I did not myself meet with this shell. Jones obtained 

 a single specimen, partly imbedded in the calcareous rock, 

 and it is therefore not unlikely that the animal is still an in- 

 habitant of the surrounding waters. 

 Lencozonia oingulifera, Lam,
