Polypus e I young). 



Polypus ornotus (pars) Berry, 1909, p. 418 (locality record only). 



Two small Polypi taken from a depth of 53-230 fathoms, Albatross station 4002, vicinity of Kauai 

 Island, constitute catalogue no. 214,383 of the United States National Museum (S. S. B. 182). They 

 agree in the following characters: 



Body small, globose, elevated dorsally; surface obscurely and distantly papillose. Head short 

 and very broad; well separated from the body by a rather deep constriction. Eyes prominent, the 

 aperture to each surmounted by a small conical cirrus and surrounded by a number of more or less 

 distinct smaller papilla?. Funnel of moderate length and width, not quite reaching to the base of 

 the arms. 



Arms attenuate; fairly stout, but in appearance slender owing to their great length; in preserved 

 specimens often much tangled and twisted; decidedly unequal, the order of length being 3, 4=2, 1; 

 the third pair vastly the stoutest, largest, and longest, attaining a length of over six times that of the 

 head and body. Suckers small, elevated, little flattened; numerous and closely crowded in each row, 

 but the two rows themselves placed quite distantly from one another along the margins of the arm, 

 the inner surface of which between them is broad and flattened. The first four or five suckers appear 

 in a single row, but distal to these the biserial condition prevails. Umbrella of moderate width, but 

 thin; continuing along the outer edge of each arm to its extremity as a delicate contractile membrane. 



Ground color of preserved specimens dull buff, heavily mottled above with dark brown, which, 

 except for a very irregular blotch or spot on either side of the body, does not appear to be distributed 

 with any special regularity. The outer aspect of the arms is mottled and reticulated. Chromatophores 

 small and numerous.

Remarks. — Upon the first hasty glance these specimens were thought to be young P. ornaius and 

 they were originally so reported. Further study has, however, persuaded me that they represent not 

 that species but some other form, the adult stage of which has not yet been obtained. The most dis- 

 tinctive features are the mottled coloration, the extraordinary development of the third arm pair, the 

 wide separation of the two rows of suckers, and the small size of the latter. 



Polypus species? 



A single specimen obtained by the A Ibatross party from a fish market in Honolulu is represented 

 only by the body and part of the head. It is too mangled for safe determination [S. S. B. 33 1]. 



Genus SCiEURGUS Troschel 1857. 



Scccurgus Troschel 1857, p. 51. 

 Saxuryus Troschel 1858, p. 298. 

 Sc&urpus Jatta 189&, p. 53, 230. 



Animal very similar to that of Polypus, but in the male the third arm of the leftside is hectocotylized 

 Type. — Scteurgus titanolus Troschel 1857 (first species named), a Mediterranean species.
