Description: The mantle is long, cylindrical, 

 and narrow (MWI 24.4-54.5-40.7). The width at 

 the edge is only slightly greater than that at the 

 middle and the sides taper into a blunt tail. The 

 mantle is muscular except for the tail which is 

 thin-walled and translucent, yet very firm. The 

 ventral anterior excavation of the mantle is 

 shallow and the lateral angles and middorsal 

 projection are low and blunt. 



Each fin is triangular and their combined 

 width is about three-fifths to four-fifths of the 

 mantle length (FWI 65.9-74.0-80.0). The fins are 

 shorter than their combined width (FLI 62.9- 

 67.5-70.0). The anterior margin is rounded and 

 the posterior margin is slightly concave. The 

 lateral angles are sharp, about 75°. 



The funnel is triangular with a broad base. 

 The funnel-mantle locking cartilage is simple 

 and typical of the genus. The groove is shallow 

 and it spreads out toward the more rounded 

 posterior end of the cartilage. The funnel organ 

 is large; the dorsal pad has a papilla and well- 

 developed ridges; the ventral pads are oval with 

 pointed anterior ends. The semilunar funnel 

 valve is wide and its anteriormost edge does not 

 reach the edge of the funnel opening. 



The head is nearly square in cross section, as 

 long as it is wide, and nearly as broad as the 

 mantle (HWI 25.6-50.9-37.5). Both dorsal and 

 ventral ocular "windows" are distinct. The eye 

 opening is a wide oval (triangular when con- 

 stricted) and has a moderately deep sinus. The 

 three crescentic nuchal folds are prominent. The 

 olfactory papilla is tonguelike and arises from 

 the nuchal fold nearest to the funnel. The funnel 

 groove is moderately deep and the sides of this 

 excavation are steep. 



The buccal funnel has eight stout supports 

 connected to the arms in the order DDVD. The 

 lappets are pointed; the inner wall of the buccal 

 membrane is very rugose and carries papillae. 

 Both membrane and supports are covered with 

 small fine chromatophores, but the membrane 

 appears darker. 



The arms are of moderate length ( ALI: I, 40.0- 

 45.4-50.0; II, 43.9-45.5-51.9; III, 47.6-5i. 5-59.2;
