Amer. Journ. Sci., xx, p. 394, Nov., 1880. 



Test thick, transparent, broad-ovate or elliptical, rounded at both ends, 

 covered, above and below, with low, rounded verructe ; aperture large, 

 occupying more than half the length of the test, broad-ovate, posterior 

 margin nearly straight; edges simple, unarmed. Animal pale pink, 

 with a brown nucleus ; fins very large, connate, broadly rounded ; their 

 outline taken together forms a long ellipse, considerably louger and 

 somewhat broader than the test. Length of test of a medium-sized 

 specimen, in alcohol, lO"""; breadth, ll""'; expanse of fins, 23'"'"; their 

 breadth, 12""'". The largest specimens have the test about 40'"'" long, 

 20'"'" broad. Stations 805 to 872 (near the surface), common; about 30 

 miles east-southeast of Block Island, at surface, October 2, 1880

Halopsyche Verrill, nom. nov. 



Psyche Rang, 1825 (wow Psyche Linnd, 1735, nee Psyche Sclirank, 1801). 



The name Psyche having been twice used before it was employed by 

 Bang, it will be necessary to substitute another name for this genus of 

 Pteropods. I therefore propose Halopsyche. 



Tbe type, and only known species, Halopsyclie glohulosa (Bang), 

 inhabits the waters of Newfoundland and Nova Scotia.
