NO. 1713. NEW CEPHALOPODA FROM PACIFIC OCEAN— BERRY. 



415 



Both tentacles unfortunately missing. 



Color of the preserved specimen a grayish buff, with a few scat- 

 tered pale-brown chromatophores ; gladius showing as a dark line 

 through the integument. 



Length, excluding arms 44 mm. ; length of mantle 39 mm. ; width 

 across fins 14.5 mm.; length of ventral arms 20 mm. 



The single known specimen was taken at station 3989, 733 fathoms 

 depth, from a bottom of coral sand and rock, in the vicinity of the 

 island of Kauai. 



C. famelica appears to differ widely from all other kno^\^l species 

 of the genus in the extreme length and 

 slenderness of the body and the very 

 lanceolate fins, the smallness of the 

 head, and the possession of relatively 

 shorter arms than usual. 



Genus CRANCHIA Leach, 1817. 



CRANCHIA (LIOCRANCHIA) GLOBULA, new 

 species. 



Body subglobular, short and round- 

 ed, the diameter almost equal to the 

 length, truncate anteriorly, poste- 

 riorly suddenly constricted, thence 

 tapering rapidly to an acute point 

 which forms the basis of attachment 

 of the fins. Mantle smooth, mem- 

 branous; its anterior margin passing 

 in three even, nearly equal, curves 

 from each point of attachment to the 

 next. These points of attachment 

 are three in number and about equi- 

 distant, one being dorsal and median, 

 the other two on either side of the 

 funnel. From the dorsal point of 

 attachment there extends posteriorly fig. 9.— liocranchia globula. dorsal 

 on the outer surface of the mantle ^^''^'''^- ^"^"'^ 



a narrow cartilaginous ridge composed of a succession of acutely 

 conical tubercles placed close together in a single longitudinal 

 series along the anterior two-thirds of the medic-dorsal line. From 

 each of the ventral points of attachment two similar ridges extend 

 back for about one-third of the length of the mantle, diverging at 

 an angle of somewhat less than 90 degrees; the tubercles minute, 

 of two sizes, irregularly alternating, each line comprising about 

 twenty, arranged in a single series and flanked near the anterior end 

 by parallel rows of two or three smaller tubercles on either side.
