Ascension. The peculiar sculpture is thesamein both c.^.. numerous small papillae, 

 which form ro.M-tte-like <-lnsicrs inside umbrella and mi dorsal anus, are present all over 

 bhe dorsal surface. The i\vo specimens are also alike in the broad head, constriction 

 between it and body, very narrow mantle-opening, and short well between dorsal arms. 

 The funnel-organ of the present specimen is not in verv Ljood condition. but appears to 

 lie W-shaped. with the median pads much narrower than the lateral ones. This mav 

 I" 1 due to contraction, however. The siphon is narrow and pointed, and extends alioiit 

 one-thi r d ,,t' the distance to the marinii of the umlirella. The radula and mandibles 

 are shown in Fin's. 7. S. All the arms are mutilated, except the fourth pair, which 

 are about four times the length of the mantle. The umlirella is verv soft, loose, and 

 semi-transparent, and measures about a quarter the length of the arms, and is much 

 extended up them.
