590 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.40. 



Head short, broad, compressed; eyes very large, lens much pro- 

 truding. Funnel thin walled and broad; the funnel organ consisting 

 of a tripartite pad shaped like an inverted V, its apex free and flap 

 like. 



Arms of moderate length, attenuate, the third pair much the largest 

 and longest, the others nearly of a length; umbrella well developed; 

 suckers in a single row, large, much elevated, and showing the peculiar 

 constriction near the apex as observed in other species of the genus. 



Gills very large, comprising about eight lamellae. 



Type.— Cat. No. 214318, U.S.N.M. From Albatross station 4396, 

 off Santa Catalina Island, California. 



Length (total) 117 mm.; of mantle 50 mm. 



POLYPUS CALIFORNICUS, new species. 



Body of moderate size, short, rounded, compact; surface covered 

 with numerous large stellate papillae which become smaller and nearly 

 obsolete ventrally; above each eye a rounded flattened tubercle 

 slightly larger than the rest. 



Head short and broad, separated from the body by a slight con- 

 striction; eyes of moderate size. Funnel rather long, conical, 

 broadly adherent to the head for the greater part of its length. 



Arms stout, moderately long, their length from two and one-half 

 to three times that of the head and body; relative order of length 

 variable; their basal quarter webbed. In the male the third right 

 arm considerably shorter than the others ; its hectocotylized portion 

 large and prominent, narrowly and deeply channeled, the excavation 

 distinctly rugose with numerous flattened transverse grooves and 

 ridges. Suckers in two rows, rather large. 



Color in alcohol a pinkish brown. 



Type.— Cat. No. 214321, U.S.N.M. From Albatross station 4325, 

 in the vicinity of San Diego, California. 



Length (total) 308 mm.; posterior tip of body to base of dorsal 

 arms 89 mm. 



POLYPUS LEIODERMA, new species. 



Body of moderate size, wider than long; nearly smooth except 

 for a few rather distant simple papillae on the dorsal surface, as well 

 as a narrow (though distinct) membranous fold bounding the outer 

 periphery. 



Head short and broad with large eyes. Funnel long and rather 

 slender. 



Arms not very long, their order 1, 2, 3, 4, the dorsal pair decidedly 

 the stouter and longer, the ventral the reverse; umbrella well devel- 

 oped, extending between the dorsal and lateral arms for over a fourth 

 of their length, but much shorter between the ventral pair; suckers 

 in two rows, small, and relatively very numerous.
