1913.] NATURAL SCIENCES OF PHILADELPHIA. 73 



Polypus pricei new species. 



Animal small and rather delicate. Body elongate pyriform, 

 obtusely pointed behind; a decided nuchal constriction separates 

 it from the head; surface everywhere smooth, without visible cirri 

 or papillae. 



Head small, short, flattened, slightly narrower than the body. 

 Eyes very large, rounded, and protruding. Funnel broad, thin 

 walled, truncate at the extremity, the tip reaching but little past 

 the base of the arms.^ 



Fig. 2. — Polypus pricei, inner aspect of right ventral arm. X 2^. [S. S. B. 189.] 



Arms nearly equal, scarcely twice as long as the body; thick 

 at the base, but delicate and tapering rather rapidly to a tenuous 

 extremity; connected at base by a thin hyaline umbrella extending 

 about equally between them all for perhaps a twelfth of their length; 

 along their outer margins it is continued as a very fragile membrane, 

 becoming obsolete considerably before it reaches the tips. Suckers 

 small, little crowded, much elevated, the first five or six pairs but 

 little displaced, so that they still have the appearance of a single row; 

 the remainder clearly biserial (fig. 2). 



Hectocotylus not observed. 



Color of specimens preserved in alcohol a very pale brownish- 

 buff everywhere except the region of the eyeball, the body and 

 head irregularly dotted with small brown chromatophores ; eyeball 

 bluish-black, with a few very large chromatophores superimposed; 

 two alternating longitudinal rows of large light colored chromato- 

 phores decorate the outer surface of each arm. 



1 Owing to the condition of the specimens I am unable to give either a drawing 

 or an accurate description of the funnel organ. The indications are, however, 

 that it is closely similar in outline to that of P. californicus (cf. Berry 1912o, 

 p. 286, fig. .3), although relatively somewhat smaller and more anterior in position.
