Head (except the eyes) small, rather elongate above and below. Funnel large, with a strong ven- 

 tral flexion; membranous, thin, much wrinkled in the preserved specimens; true valve lacking, its 

 place taken by a thickened fold or pseudo-valve on the dorsal wall just in advance of the median pad 

 of the funnel organ. Funnel organ highly complicated, comprising three distinct components, as follows: 

 A large, rounded ovate, flattened pad on each ventro-lateral wall; between them a large, conspicuous, 

 median, liver-shaped pad, its convex outline directed forward; from its center rises a long papilla, 

 robust at the base, but tapering and terminated by the anal aperture; lateral lobes of this pad broad 

 and rounded, each of these also giving rise near its center to a rather large, soft, bluntish papilla, which 

 appears to terminate blindly in a rounded, finger-like extremity. The general arrangement of the 

 entire apparatus is represented in the annexed diagram (text fig. 17), as well as in figures 5-6 of plate 

 Liv. Eyes relatively enormous, globular, sessile, nearly approaching in the median line below; open- 

 ings small. 



Sessile arms moderately short, about one-fourth as long as the body, unequal, their order 4, 3, 2, i; 

 rather slender and delicate, each bordered by a broad, extremely delicate, hyaline membrane strength- 

 ened by numerous fairly slender, tran.sverse trabeculse having their origin near the base of the suckers 



(pi. XLVi, fig. i). Suckers small, subsphcrical, 

 obliquely placed on very short pedicels in two 

 regularly alternating rows of about 20 to 25 each; 

 homy rings well developed, but delicate and 

 smooth (text fig. 18). 



Tentacles long, somewhat stouter at the base 

 than the sessile arms and about twice as long; 

 inner surface flattened and with a median groove, 

 on either side of which appears a row of minute 

 flattened suckers (about 18 in all), regularly but 

 distantly alternating with as many small, more or 

 less obscure, circular pads (pi. xl\t, fig. 3). Dis- 

 tally the pads and suckers move closer together 

 and their ranks exhibit a tendency to separate in 

 alternation to form four rows, the entire apparatus 

 terminating on the carpal portion of the club in a 

 compact group of about eight suckers and the same 

 number of pads, still minute although much larger 

 than those of the stalk. Club slightly expanded, 

 furnished with a thin marginal membrane; ex- 

 panded portion armed with two alternating rows of large delicate hooks, 12 in all, succeeded at the 

 extremity of the club by a group of very minute suckers. Hooks of very characteristic appearance; 

 sheaths hood-like; bases broadly expanded; a single isolated sucker of exceeding minuteness occurring 

 near the proximal end of the dorsal row (pi. xlvi, fig. 2). 

 Buccal membrane well developed, suckerless. 



Gladius not removed, but in large part easily apparent through the dorsal integument; fragile; 

 excessively slender and attenuate. 

 Radula not examined. 



Color in alcohol a soiled white, the chromatophores appearing as indistinct brownish spots thickly 

 scattered over the dorsal surface of the head and on the tentacles (notably on the inner surface of the 

 club); much less numerous but more distinct on the ventral portion of the head and the dorsal surfaces 

 of the fins; on the mantle only a few large ones sparsely distributed. 

 The chief dimensions of the single specimen seen are as follows:
