Fleurotoma {Beta) limacina Dall. {Daphnella f) 



Bulletin Mns. Comp. Zool., ix, p. 55, 1881. 



Four living specimens of this elegant shell were taken at station 994^ 

 368 fathoms. Gulf of Mexico, 447-805 fathoms (Dall). This is not a 

 true Bela^ for it has no operculum ; ejes minute. 



Capnlus hungaricus (Liuu<§). 



Two living specimens were obtained, which appear to belong to this 

 species. They are more delicate and have somewhat finer and more 

 regular radiating ribs than the ordinary European form. It has not 

 been recorded before from our coast. 



Stations 922, 1029 ; GO and 458 fathoms. 



Fiona nohilis Alder and Han. 



British Nud. Moll., J^olidse, Fam. 3, pi. 38 A. 



A large and handsome Fiona, apparently this species, was found in 

 two instances, in large numbers, on pieces of floating timber, among 

 Anatifers, at stations 935 and 995. They were kept in confinement 

 several days and laid numerous clusters of eggs. These are in the form 

 of a broad ribbon, spirally coiled in about one and a half turns, so as to 

 form a bell-shaped or cup-shaped form, and attached by a slender pedicel, 

 so as to hang from the under side of objects. Alder and Hancock re- 

 corded its occurrence, in a single instance, at Falmouth, England. 



Issa ramosa Verrill and Emerton. 



Body elevated, convex above, elongated, oblong, sides nearly parallel 

 along the middle ; foot well-developed, as broad as the body. Dorsal 

 tentacles thick, clavate, obtuse, with numerous lamellae; sheath scarcely 

 raised. Back and sides with numerous small, simple papillae. Along 

 the lateral margins of the back there is a carina, with a row of large, 

 much branched papillae, alternating with much smaller ones; of the 

 large ones there are about six on each side, the most anterior are below 

 the dorsal tentacles ; two on each side are posterior to the gills, the last 

 ones largest ; a row of similar but smaller processes extends below the 

 tentacles and around the front margin. 



Gills five, arborescently branched. Color, pale yellow. The dorsal 

 tentacles darker. 



The radula is quite different from that of I. lacera and Triopa claviger. 

 The median area is wide, with two rows of thin, transversely oblong 

 plates ; there are three rows of large, nearly equal teeth on each side, 

 with the tips stronglj^ incurved, obtuse ; the innermost tooth has a 

 small lobe on the middle of the inner edge : these are followed by about 

 seventeen or eighteen smaller, oblong plates, with slightly eraarginate 

 anterior ends ; these gradually decrease in size toward the margins of 

 the radula. 



Stations 940, 049 ; 130 and 100 fathoms.
