H. A. Pllsbry — Air-breathing MollusJcs of the Bermudas, 497 



I was told that it was abundant in the vicinity of Hamilton several 

 years before it spread to Bailey's Bay and other parts of the 

 main island. It is not found on the smaller islands. — (A. E. Y.) 



Subulina octona (Chemn.). 



Plate LXII, Figure 4. 



Reported from Bermuda by Bland in 1881, and found by Aldrich, 

 Heilprin, and by Verrill's party. Common under stones. — (A. E. V.) 



Opeas octonoides (C. B. Ad.). 



Several small specimens taken by Prof. Heilprin's party in 1888. 



Opeas swiftianum (Pfr.). 



Plate LXII, Figure 5. 



Twenty specimens taken by the pai'ty of 1888. It is known from 

 St. Thomas, St. John, Porto Rico, and Vie que. Whether this and 

 the preceding two Antillean species were introduced by natural 

 means or by human agency is not known with certainty, but their 

 recent detection strongly indicates the latter alternative. 



Csecilioides acicula (Mull.). 



Reported by Bland in 1861, and by Jones in 1876, but not found 

 by later collectors, so far as I know. 



Family PUPID-ffi. 



Mr. M. C. Cook of our party notes that most of the Pupidfe in 

 our collection were obtained from under stones in a field opposite 

 Mr. Seon's residence at Bailey Bay, where they were abundant. 

 Some dead ones were found on Bailey Bay Island and on Trunk 

 Island in Harrington Sound. — (V.) 



Pupa (Bifidaria) servilis Gld. 



Plate LXII, Figure 6. 



This is Pupa pellucida of Bland's list, and probably in part Pupa 

 bermudensis of Prime, though the latter may have been based upon 

 the following species, or both. Originally described from Cuba, the 

 species is known from various West Indian islands. Alt. 2.7'"'".
