Family SUCCINEID^. 



Succinea barbadensis Guild. 



Guilding, Zoological Journal, iii, p. 532, Suppl., pi. 27, f. 4-6. 



/S. hermudenais Pfr., P. Z. S., 1857, p. 110; Monographia, iv, p. 817. 



Variable in length of the spire, but I am unable to recognize more 

 than one species in a series of several hundred shells collected by- 

 Swift, Bland, Vathelet, Heilprin, and Verrill. 



The several Succineas reported from Bermuda — S. margarita Pfr., 

 S. fiilgens Lea, and S. hermudensis Pfr., — seem to me to be merely- 

 varying identifications of a single species, the S. hermudensis of 

 Pfeiffer. On comparing -with S. harbadensis Guilding, from Barba- 

 dos, I must agree with Mr. Smith' that there is no difference between 

 the shells ; but the shells of this genus are peculiarly- uncharacteris- 

 tic, species of different regions frequently resembling each other. 

 Probably- the soft anatomy- will give better specific characters, as in 

 the slugs. 



Taken in large numbers in the crevices of the bark of a large tree 

 in Miss Peniston's grounds. — (Cook.) 



Family VEBONICELLID.^. 

 Veronicella schivelyae (Pilsbry). 



Vaginulus schivelyce Pils., Proc. Acad. Nat. Sci., Phila., 1890, p. 297, p. 5, f. 6, 7, 8. 



Two specimens were taken by Miss Mary Schively, a member of 

 Professor Heilprin's class, in 1888. A few years later I was told that 

 the species had become abundant and destructive to vegetables. 

 Professor Verrill obtained a number of specimens, Ow-ing to its 

 nocturnal feeding habits, it is not likely to be conspicuous to the 

 casual visitor. 



In coloration it varies from heavily blotched in two bands along 

 the back, to mere indications of the bands. While it would seem 

 likely that the species is an introduced one, I have been unable to 

 identify it with any of those described from other regions. 



Nearly all of our specimens were obtained, with many other pul- 

 monates, by examining the whitewashed surfaces of the stone fences 

 and outhouses by the light of a lantern, late at night. The largest 

 were 8 to 10 inches long when extended. — (A. E, V.)
