Habitat. — Sandwich Islands (Honoruru). 
One specimen was taken on the Reefs of Honoruru ; it was preserved in alcohol, and 
was rather contracted. Its length was about 4 cm., with a breadth of 2 ’5 cm. and a height 
of 17 cm.; the breadth of the mantle edge was from 1 to 4 mm., behind about 9 mm.; 
the height of the retracted rhinophoria about 3 '5 mm., and of the retracted branchia 
5 mm., the diameter of the branchial cleft about 275 mm. ; the breadth of the foot 
l - 5 cm., the length of the tail 3’5 mm. The colour of the dorsal surface was of a bluish- 
grey, of the sides of the body yellowish -grey, with an indication of two or three longi- 
tudinal bands formed of series of spots ; the sole of the foot also was of a yellowish-grey ; 
the branchia and rhinophoria bluish-black, the latter with a whitish terminal papilla. 
The form of the body, as far as could be made out, is longish and stout ; the edge 
of the mantle undulating, and gradually increasing in breadth from before backwards, 
where it forms a kind of caudal veil ; its under surface is smooth. The dorsal surface 
is everywhere strongly wrinkled, and therefore is everywhere divided into variously-sized 
1 The Family Doriopsidie contains the remarkable genus D oriopsilla, which differs from Doriopsis by its stiff body 
and hard granulated back, and also by the position of the buccal ganglia. But one species, Doriopsilla areolata, 
Bergh, from the Mediterranean, is known ; but perhaps Doriopsis rjranulosa of Pease is in reality a Doriopsilla.
