564 FROCEEDINQS OF THE NATIONAL MUSEUM. vol. 45. 



SCAEURGUS PATAGIATUS, new species. 



Body small, short, rounded, compact; dorsal surface heavily tuber- 

 culate with small roimded papillae which often coalesce to form longi- 

 tudinal ridges, the arrangement of the latter showing a greater or less 

 bilateral symmetry ; a narrow keel bounds the periphery of the body 

 on the sides but is discontinuous posteriori}'- ; there is a large cirrus 

 over each eye opening, with a smaller one just in front. 



Head broad, but narrower than the body; eyes large. Funnel 

 organ W-shaped. 



Arms stout, somewhat over twice as long as the head and body 

 taken together; subequal, the second pair slightly the longest. Um- 

 brella well developed, especially between the dorsal arms. Third 

 left arm in the male conspicuously hectocotylized ; calamus very long 

 and slender; the ligula spoon shaped, its inner face deeply excavated. 



General color of living animal, pale green; of alcoholic specimens, a 

 brownish buff marbled with chocolate. 



Type.— Csit. No. 214379, U.S.N.M. [S. S. B. 204]. From Albatross 

 station 4079, off the island of Maui. 



Length (total), 152 mm.; posterior tip of body to base of dorsal 

 arms, 46 mm. 



EUPRYMNA SCOLOPES, new species. 



Body small, sepioliform, of variable outlme. Fins large, semicir- 

 cular, attached in advance of the middle of the body. Nuchal com- 

 missure wide. 



Head short, about the same width as the mantle; eyes large. 



Arms short, stout, about as long as the mantle, their order of rela- 

 tive length 2, 3, 4, 1. Umbrella rudimentary between the dorsal 

 arms and those of the ventral pair, but elsewhere better developed. 

 Suckers on all the arms in four rows except at the extreme base and 

 tip, where they are in two rows; pedicels short, stout; cups spherical, 

 with small apertures ; homy rings smooth. In the female the suckers 

 on all the arms are relatively minute and subequal, but in the male 

 some 6 to 10 suckers in each marginal row on the second, third, and 

 fomth arms undergo a conspicuous enlargement; left dorsal arm of 

 male hectocotylized — the first four pairs of suckers at the base in two 

 rows, these succeeded by 10 quartets of small suckers, the two basal- 

 most of the ventral row of which are reduced to slender papillae; be- 

 yond its basal third the arm becomes much swollen, while the suckers 

 of the two ventral rows are replaced by an irregular crowded series 

 of transversely compressed papillae, which continue to the tip, each 

 bearing a minute aperture at its inner apex with a minutely toothed 

 horny ring; the suckers of the two dorsal series imdergo modification 

 a Httle later than their ventral neighbors, fuially appearing as a 

 crowded double series of swollen tubercles which are neither so com-
