including teeth, 6'5 ; length of pedicels, 5 ; distance between pedicels, 

 15™". The large suckers agree very well with those described and 

 figured from the type-specimen (PI. XXI, fig. 9) ; this portion of the 

 club had nine of these large suckers in each row ; their pedicels arise 

 from the middle of deep squarish depressions, between which run 

 thick transverse ridges, which bear the smaller marginal suckers 

 toward their outer ends, and then support the marginal membrane. 

 A part of the large suckers have retained their horny rings, but all 

 the marginal and small distal suckers have lost them. The horny 

 rings of the large suckers (fig. 5a) are oblique, much higher on the 

 outer than on the inner side ; the edge bears about 28 sharp, incurved, 

 well-separated, unequal teeth ; of these the largest is at the middle of 

 the outer edge ; another smaller one, but larger than its fellows, is at 

 the middle of the inner edge; two others, in size similar to the last, 

 occupy the middle of the lateral edges ; thus the edge is divided 

 into four equal parts, by the four larger teeth, between which there 

 are five or six smaller, very acute teeth, separated by spaces greater 

 than their breadth. The horny rings are amber-brown, the teeth are 

 golden yellow at tip. The distal portion of the club is compressed, 

 with the face narrow and tapering, but with an elevated dorsal keel ; 

 it bears four crowded rows of small, pedicelled suckers, the two 

 rows on one side of the median line being composed of very much 

 smaller suckers than the other two. At the very tip of the club 

 there is a round cluster of small, smooth suckers, as in Architeuthis. 

 The buccal mass is 52"'" in length and 42 in diameter. A thick 

 buccal membrane, covered with low, irregular verrucae, surrounds the 

 jaws. The jaws are sharp and strong ; their exposed portions are 

 black, the ala3 reddish brown. The beak of the upper jaw is long, 

 strongly incurved, acute, its cutting edge regularly curved, with a 

 deep notch at its base, from which a well-defined groove runs down- 

 ward. The lower jaw is sharp, its cutting edge is most concave near 

 the tip, below which it is nearly straight, sides covered with fine 

 radiating lines; basal notch broad, shallow, angular; beyond the 

 notch there is a broad, low angular tooth. The surface of the fleshy 

 palate is covered with low rounded verrucae. The odontophore is 

 broad, with sharp, pale amber-colored teeth, which agree well with 

 those of the original specimen (Plate XXI, figures 3-7) ; outside of 

 the lateral teeth there is a narrow, raised, chitinous ridge, apparently 

 not divisible into plates. 



Another specimen, consisting of the buccal mass and jaws, but 

 without the odontophore, was presented to the TJ. S. Fish Comrais-
