DIACxNOSES OF NEW CEPHALOPODS FROM THE HAWAIIAN 



ISLANDS.

Prior to the publication of a final report on the ccphalopods col- 

 lected by the U. S. Bureau of Fisheries steamer Albatross in the 

 Hawaiian Islands it was deemed best to issue the present paper to 

 contain preliminary diagnoses of such forms as are believed to be 

 new, leaving more detailed and completely illustrated descriptions 

 until the appearance of the main report. It is hoped, however, that 

 the following observations will, in the meanwhile, prove useful to 

 other students of the group and sufficient for the ready recognition 

 of the species. 



The illustrations for this paper are from drawings by ^Ir. Henry V. 

 Poor, excepting fig. 1, which is from a photograph by Mr. John H. 

 Paine, of Stanford University. 



Genus POLYPUS Schneider, 1784. 

 POLYPUS HOYLEI, new species. 



Body rounded, depressed above and below, about as long as 

 broad, covered with a loose skin of a rather gelatinous consistency; 

 an obscure longitudinal groove in the median ventral region. Man- 

 tle-opening small and lunate, extending but little beyond the funnel 

 on either side. 



Head broad ; neck slightly constricted ; eyes very large, with small 

 openings, above which on either side are two prominent, nipple-like 

 tubercles or cirri, each with a pore-like depression in its center. Near 

 these are one or two fainter and smaller papillae, and a few others, 

 equally or more obscure, are scattered over the dorsal surface of the 

 body. 



Surface, except for the above-mentioned tubercles and papillae, 

 smooth, very finely reticulated with extremely minute papilla or 

 wrinkles, and very soft to the touch, which are apparently not due 

 to the action of the preserving fluid. 



Siphon of moderate size, bluntly conical, connected above with 

 the basal portion of the umbrella and extending forward for about 

 one-third the length of the latter.
