[July, 



surface is quite heavily and evenly papillose with either (1) soft 

 polygonal tubercles, or (2) almost a shagreen of small stellate warts, 

 or (3) fairly smooth when poorly preserved. Ventrally the papillae 

 become nearly obsolete. A group of two large and several smaller 

 papillae surmounts either eye. 



The arms are almost of a length, the second pair slightly longer 

 than the others, but not much more than twice as long as the head 

 and body taken together. They taper evenly to slender extremities. 

 In the male the third right arm is only a little shorter than its mate. 

 The very ample marginal canal is transversely striate within and 

 terminates in a faint groove running down the inner face of the 

 small naked elongate-conical hectocotylus. One sucker of the fifth 

 or sixth pairs on each lateral arm shows a conspicuous enlargement. 



The color of preserved specimens is a dark slaty-brown, paler 

 below and on the inner surface of the umbrella. Obliquely in front

of and below the eye on either side is a conspicuous eye-like spot, 

 comprising a dark outer ring enclosing within it a narrower ring 

 of a lighter color (usually bluish and showing a faint metallic lustre), 

 and within this a central zone of the same dark shade as the outer 

 ring. There is also a definable but less conspicuous ovoid spot 

 between the eyes of a lighter and browner tint than the general 

 surface. The ocular markings of the six specimens in the Stanford 

 University collection seem much larger than those of the animal 

 figured by Hoyle in the Challenger Report, but I have no doubt 

 b that they are correctly referred to the same species. 



i measurements of a well-preserved male are given below, the 

 men referred to being No. 148 of the author's register.
