KO. 2335. NEW CEPHALOPODS FROM WESTERN ATLANTIC— BERRY. 299 



line streak in the mid-dorsal line; a longitudinal series of cartilagi- 

 nous tubercles on each side, ventrally, extending back from the points 

 of attachment of the mantle. Fins with anterior and posterior out- 

 lines somewhat flattened, but broadly adherent to the tip of the 

 body so that together they form a robust transverse ellipse. 



Head small, conical, prolonged in front as a long, columnar, ob- 

 scurely quadrangular, ventrally flattened snout. Eyes of moderate 

 size, pyriform, projected into a point forward and ventrally, dis- 

 tinctly constricted between the bulbus and the large rounded optic 

 ganglion; eyestalks long, stout, cyhndrical, transparent, not quite as 

 long as the snout; bulbus with an oblique series of four small pho- 

 tophores on the inner ventral aspect, and there are possibly others. 

 Funnel long, reaching well past the base of the eyes. 



Arms small and slender, their formula of relative length 3, 4 = 2, 1; 

 the third pair fully three times as long as the second and fourth, 

 which to an only less degree than the dorsals are small and weakly 

 developed. Suckers small, in two fairly well-separated rows. 



Tentacles long, much stouter and more robust than the arms; 

 their clubs but slightly expanded, keeled, and bearing four rows of 

 suckers, the two median of which on the expanded portion of the 

 club are conspicuously the largest; two rows of suckers, greatly re- 

 duced in size, continuing down the distal half or two-thirds of the 

 tentacle stalk. 



Total length, 55 mm.; length of mantle (dorsal) 32 mm. 



Type.— C&t. No. 338698, U.S.N.M. [S.S.B.582]. 



Type locality.— Suri&ce, Station 10161, latitude 35° 27' N., 

 longitude 73° 14' W., East of Cape Hatteras; January 28, 1914. 



Remarks. — This species seems without doubt to be most nearly 

 allied to the Chilean P. sclmeeMgeni Pfeffer, and may conceivably 

 represent only an Atlantic race of the same stock, but the published 

 descriptions of the latter indicate that certain differences exist. 

 Chief among these are, in the Chilean species, the shorter funnel, 

 not reaching to the base of the eyestalks, the decidedly triangular 

 fins (although their shape as described is no doubt partly due to the 

 conditions of preservation), the alleged distribution of suckers only 

 along the distal third of the distinctly shorter tentacle stalks, and 

 the relatively shorter arms, even the third pair of which is exceeded 

 in length by the snout. 



Genus POLYPUS Schneider, 1784. 



POLYPUS SCORPIO, new species. 



Plate 16, fig. 4. 



Diagnosis. — Body small, ovate to pyriform, rounded or rounded- 

 conic behind. Mantle opening ample, extending to a point well 

 back of and just below the level of the pupil.
