A. E. Yerrill— Additions to the Fauna of the Bermudas. 35 



Length, in life, -So to 45'^"\ 



Taken in considerable numbers in the mangrove swamp at Hungry 

 Bay, on a filamentous green alga, March 10th, 1901 (A. H. V.). In 

 April (5th) both the alga and the mollusk had disappeared. 

 . This is a very handsome and active species. It is difficult to pre- 

 serve entire, for it casts its papillae very readily when irritated in any 

 way. 



It is named in honor of Mr. T. Goodwin Gosling, of Bermuda, 

 who first discovered it. I have referred it to lacelina with some 

 doubt, for its anatomy has not yet been fully studied. 



PROSOBRANCHIATA. 



Volva uniplicata (Sowerby).

 Volva uniplicata Tryon, Amer. Marine Conch., p. 93, pi. ix, fig. 93, 1873. 



The purple variet}' of this species was found adhering to a purple 

 specimen of Gorgonia flahellum, from Castle Harbor reefs. 



PULMONATA. 



Among the Pulmonata, apparently not before recorded, are the 

 following : 



Melampus bullimoides Mont. Shore of Hungry Bay. 



PBlaumeria heteroclita Mont. Shore near Hungry Bay, under stones. 



Also an undetermined, small, strong!}^ depressed, smooth, helicoid 

 shell, 8 to 10™™ in diameter; the aperture is simple, lunate; lip 

 acute ; umbilicus open and deep, but not very large. Hamilton, in 

 gardens. 



BIVALVIA. 

 Cardium medium Linue. 



A single dead specimen of this West Indian species was found in 

 the cavities of a stone fished up from about 100 feet deep, off the 

 outer reefs. 



ECHINODERMA. 



Only one species, so far as positively determined, was added to 

 the Echinoderma this year. This was an interesting simple-armed 

 astrophytid {Astroporpa affinis), which Avas found clinging to a 

 Verrucella from off the outer reefs. 



Several other species of special interest were obtained, which Ave 

 did not collect in 1898.
