Genus COCCULINA Dall. 



Cocculina Beanii Dall. 



Collected at Station 2754. east from Tobago, in 880 fathoms, ooze; 

 temperature 37°.9 F. Tectum adunca Jeffreys, as far as one can tell 

 from an examination of the shell alone, is a synonym of this species. 



Cocculina pocillum sp. uov. 



Shell small, stout, short, high, arched in front, bluish white, with a 

 dark brown epidermis; ends evenly rounded, sides nearly straight on 

 the margin; sculpture of numerous larger obscure radii, each pair with 

 about three finer intercalary ones, slightly scalloped by the very line 

 slightly raised incremental lines; over all where the surface is perfect 

 is a fine, dust like, microscopic granulation; margin entire; apex pro- 

 jecting backward, decnrved iu the posterior third of the length ; the 

 summit arched slightly above it; interior bluish white, polished; maxi- 

 mum longitude, 5,5; latitude, 3.7 ; altitude, 3.5; apex iu front of hinder 

 margin, 1.5""". 



Hab. — With the preceding species. 



This species is not much like any of those previously described. Two 

 male specimens were taken, each with a well marked verge extending 

 from the right tentacle. It has no posterior epipodial filaments, and 

 therefore should be placed iu the section or subgenus Coccopygia.
