' Challenger ' Cephalopoda. 235 



The Colour of the body is creamy white, of the arms and 

 umbrella deep madder-brown. The suckers and cirri are 

 paler. 



Hah. Off the Meangis Islands, near the Philippines, 

 500 fathoms (Station 214). One specimen, sex? 



Cirroteuthis pactfica, n. sp. 



The Body is almost entirely absent. The fin is obovate in 

 form and thickened along the posterior margin, thin and 

 membranous at the extremity and along the anterior margin. 

 The proximal end of its cartilage is exposed and presents a 

 long grooved articular surface. One branchia is visible and 

 presents the appearance of a spheroidal nodule with meridional 

 grooves. The mantle-opening is circular, and closely embraces 

 the base of the siphon, which is long, thin, and conical. 



The Head is exceedingly short, and the eye appears to occupy 

 all the available space between the fin and the arms. 



The^rms are subequal, thick, rounded, and soft, and taper 

 rapidly towards the extremities. The umbrella is attached 

 directly to the arms, which are somewhat more prominent on 

 its inner than on its outer surface ; it is attached to the dorsal 

 aspect of every arm almost to the tip, and to the ventral 

 aspect for somewhat more than half its length, and at its at- 

 tachment is a firm cartilaginous (?) nodule. The suckers are 

 about fifty-two in number and commence close to the oral 

 lip, and the first half-dozen stand near together ; halfway up 

 the arms they are further apart, and the largest are situated 

 opposite the attachment of the membrane to the ventral aspect 

 of the arms ; they are prominent, but not so hard and firm as 

 those of C. magna. There are faint radial markings upon 

 them. The cirri commence on the dorsal arms between the 

 seventh and eighth suckers, and continue till the last ; on the 

 ventral arms they commence between the sixth and seventh, 

 and here also are continued to the tips of the arms. They 

 begin as small papilla?, gradually increase in length, attaining 

 their maximum about halfway along the arms. 



The Surface is smooth. 



The Colour is a deep purplish madder, paler outside the 

 umbrella and on the fin. 



Hab. Pacific Ocean, between New Guinea and Australia, 

 surface (Station 181). One mutilated specimen, sex?
