408 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 37. 



Arms rather short and stout, nearly equal, the third pair the short- 

 est (a character especially noticeable in the male) ; length about twice 

 that of the head and body taken together; umbrella very wdde, extend- 

 ing between all the arms in the adult (male) for nearly half their 

 length; suckers rather large and closely set, in two rows save at the 

 base, where there is but a single row; none of those of the male show- 

 ing any appreciable enlargement. 



Ilectocotylization affecting only a small portion of the extremity 

 of the arm of the male, its transverse ridges rendered obscure or obso- 

 lete by the gelatinous consistency of the skin. 



Color of preserved specimens a brownish-red above, more pinkish 

 below. Chromatophores minute and numerous, especially on the 

 upper surface, where they are quite evenly distributed in veins, the 



interstices between which appear 

 as pale reticulations upon a darker 

 background. 



Length of body 65 mm.; of 

 second arm-pair 161 mm.; width 

 of body 45 mm. The type is a 

 specimen obtained by the Alba- 

 tross expedition, but preserved 

 without any locality label. It is 

 an adult male. 



Further specimens are in the 

 collection as follows : station 4 11 ,

The present species is apparently close to P. januarii Steenstrup," 

 from which it is readily distinguishable by the smaller mantle- 

 opening, double cirri above the eyes, order of length of arms, their 

 relative shortness, etc. 



Named in honor of Dr. William E. Iloyle, to wdiom we owe much 

 of our knowledge of this fascinating group of animals, and whose 

 masterly memoirs are among our most important classics in their 

 study. 



STEPHANOTEUTHIS, new genus. 



Body sepioliform, short, saccular. Medio-dorsal margin of mantle 

 free from head, but articulating therewith by a very rudimentary 

 groove and cartilaginous ridge; ventral margin produced forward 

 below the eyes, completely covering the funnel, with the base of 

 wdiich it articulates on either side, by a prominent cartilaginous con- 

 nective apparatus.
