2335. NEW CEPHAL0P0D8 FROM WESTERN ATLANTIC— BERRY. 295 



ENOFTKOTfiUTHIS SPINICAIJDA, new species. 



Plate 16, fig. 6. 



Diagnosis. — Body very short, vasiform, swollen just behind the 

 middle, thence tapering abruptly to continue between and past the 

 fins and as far again as a delicate, needlelike process consisting 

 principally of the excessively produced and attenuated posterior 

 prolongation of the cone of the gladius. Fins almost perfectly semi- 

 circular, but their anterior and posterior margins a little flattened so 

 that together they form an immense, nearly circular, transverse ellipse, 

 half again as long as the body proper. No evident traces present of 

 an accessory membrane of fin. 



Head fairly large, oblong, flattened, produced in front as a long, 

 four-sided, snout-like process leading to the arms. Funnel moderate, 

 the funnel cartilages more or less ovate. Eyes enormous, pushed 

 forward on short, heavy, columnar stalks, composed mainly, it would 

 seem, of the immense optic ganglia. 



Arms moderate, the lateral pairs somewhat the longest (perhaps 

 two-thirds as long as the body proper), the formula of relative length 

 being 2, 3, 4, 1, or 2, 3, 4 = 1. Suckers in two rows, quite large in 

 proportion to the arms. 



Tentacles about twice as long as the arms, the club minute, not 

 expanded, bearing but four suckers arranged in two rows, the three 

 proximal ones much the largest. 



No luminous organs evident. 



Total length, about 25 mm.; length of mantle (dorsal), about 

 17 mm. 



Type.—Ciit. No. 338694, U.S.N.M. [S.S.B.638]. 



Type locality.— 75-0 m., station 10188, latitude 28° 51' N., longi- 

 tude 70° 08' W.; February 24, 1914. 



Remarlcs. — This extraordinary little squid possesses a combination 

 of very puzzling features. It has a manifest resemblance in its 

 general f acies to many of the Chiroteuthidae, and that the relationship 

 is a more than fancied one is indicated by the form of the locking 

 cartilages which does not support its reference to any other family 

 as well. Nevertheless there are discrepancies, as the tentacles show 

 but two rows of suckers on the club, and the ventral arms fail to 

 exhibit the predominance so generaUy characteristic of these organs 

 in this famfly. The stalked eyes are also quite peculiar in structure. 



Genus TEUTHOWENIA Chun, 1910. 



AscoTEUTHls, new subgenus. 



Cranchiids of moderate size, with strongly inflated mantle, showing 

 evident resemblance to Teuthowenia s. s., but differing in the much 

 larger, almost semicircular fhis, funnel shorter than the strongly
