Animal dark browm, reddish at the peduncles ; mantle thick, 

 dark grej, freckled with white ; body roughly fm-rowed ; the 

 pedal row very distinct ; the elongated tubercles composing it 

 whitish, basal edge pale grey ; tail truncated ; gland large, sub- 

 rotundate, surrounded by a swollen margin ; mantle lobes small. 

 The animal very closely resembles that of JV^. ligulata, in a less 

 degree N. orohia, the tail of which is less truncate, &c., and 

 some species of Ariophanta. This description is taken from some 

 of my own notes and from those of Dr. Stoliczka, which accom- 

 jianied an excellent drawing, made under his supervision.
