ART. 18 SMALL, SHELLS DREDGED BY *'aLBATEOSS" DALL 121 



Genus COCCULINA DaiM882 



COCCULINA RETICULATA Verrill 



Cocculina reticulata Verrill, Trans. Connecticut Acad. SjL, vol. 6, p. 426, 

 1885. 



One specimen off Fernandina. Off Marthas Vineyard and south to 

 St. Kitts, West Indies, United States Fish Commission. 



COCCULINA GEORGIANA, new species 



Shell small, ovate, white, the sculpture like that of C. reticulata; 

 the apex at the posterior third, slightly arcuate, the nepionic shell 

 small, subcylindricai, horizontally projecting, smooth; sides nearly 

 parallel, the posterior end a trifle wider; the ends evenly rounded, 

 the margins entire. Length, 3.5 mm.; width, 2.5 mm.; height, 1.7 

 mm. U. S. Nat. Mus. Cat. No. 108281. 



Off Georgia, 20 specimens. 



Like C. reticulata in a general way but uniformly smaller and with 

 a different apex. 



COCCULINA? ROTUNDA, new species 



Shell small, elevated, conical, white, apex central, erect, blunt; 

 surface with concentric incremental lines and occasional extremely 

 faint sparse radiating lines; aperture circular, margin entire. Height, 

 2.1 mm.; diameter, 3.2 mm. U. S. Nat. Mus. Cat. No. 108156. 



Off Fernandina, six, and off Georgia, nine specimens. 



The symmetrically rounded cone is so different from the form of 

 most of the other species as to give rise to a suspicion that this may 

 not be a true Cocculina. 



Genus BASILISSA Watson, 1879 



BASILISSA (ANCISTROBASIS) RHYSSA.new species 



Shell very small, turbinate, brownish, with six slightly rounded 

 whorls and a minute transparent, glassy nucleus of about one whorl; 

 the whorls acutely carinate; suture distinct, not deep; axial sculpture 

 of small flexuous equal and equally spaced threads ceasing at the 

 carina; base smooth, polished, with a shallow depression in front of the 

 carina; the umbilicus small, deep, funicular, with no keel at the 

 verge; spiral sculpture of one or two prominent keels between the 

 suture and carina, very slightly affected by the axials, and a few faint 

 spiral striae; aperture subquadrate (mature?), the margins thin and 

 flexuous. Height, 2 mm.; diameter, 2.1 mm. U. S. Nat Mus. Cat. 

 No. 108145. 



Off Georgia and Fernandina, not rare. Also at station 2 of the 

 BlaJce, off Cuba, in 220 fathoms. 



The brownish color may be adventitious. The small size and 

 compact form are its chief characters, with the rather rough sculpture.
