in many cases been noted as a characteristic of the West Indian 

 fauna. Thus, of the various species of Triton, Triton chlorostoma and 

 T. tuberosus are members of the Mauritian fauna, and Triton cyno- 

 cephalus and T. pileare of the fauna of tlie Philippines ; Ranella 

 cruentata crops up in the variety R. rhodostoma, from Mauritius. 

 Again, Epidromus concmnus, from the Philippines, is represented in 

 our collections by a number of individuals which are absolutely 

 undistinguishable, both in shell ornamentation and color-markings, 

 from the Pacific specimens, although they differ somewhat from the 

 closely related^. Sivifti, from Antigua. A number of other forms, com- 

 mon to the west coast of Africa and to the southern waters of Europe, 

 also occur. Among a number of American west coast species which, 

 I believe, have not hitherto been recorded from the Atlantic may be 

 mentioned Chama exogyra and Telllna Gouldii, both from the 

 Californian coast. In the case of both of these forms I have very 

 carefully satisfied myself as to absolute identity. Area solida from 

 the west coast does not appear to differ measurably from A. Adamsii^ 

 a West Indian form which has its representative in the Bermudian 

 fauna. 



The following notes on new species are given in advance of the 

 publication of the full list. 



CEPHALOPODA. 



Cuttle-fishes are said to be abundant in the Bermudian waters, but 

 we Avere not very successful in our search after these animals. Two 

 moderately large octopods, Avhich we could only see, but not obtain, 

 may possibly be the common AVest Indian Octopus vulgaris, or one 

 of the forms that have been separated off from it as a distinct species. 

 We made considerable efforts to capture one of these, but all 

 our attempts to dislodge the creature from its hold upon the interior 

 of a rock crevice were unavailing. The following species Avas ob- 

 tained beneath a stone on the beach of Flatts Village. 



Octopus chromatus, n. sp. (PI. 16, ffg. 1.) 



Body spheroidal, somewhat acuminate behind, and impressed, but 

 not furroAved, ventrally; mautle opening extending about one-half 

 around the circumference of the body, and terminating some distance 

 below and back of the eyes. The head not much narrower than the 

 body ; eyes not conspicuous, with a Avart above each ; funnel largely 

 free, reachiug about half way to the base of the web, Avhich is about 

 as long as the body and head combined.
