294 A. E. Verrill — North American Ceplialopods. 



die; these have lost their horny claws; series of minute, slender-pedi- 

 celled suckers run along the club, either side of the median line, and 

 beyond the large hooks these rows unite and entirely cover the face of 

 the distal third of the club (fig. 1, d), there forming about eight rows ; 

 at the tip there is a cii-cular group of minute suckers [d') ; toward the 

 base of the club the lower side is expanded and bears a row of five 

 peculiar suckers (fig. 1, e), having a marginal series of slender, 

 minute, incurved spinules ; these suckers have very thick basal pro- 

 cesses, which are appressed and directed toward the central line of the 

 club, bearing the suckers on their inner ends, attached by short pedi- 

 cels ; round connective tubercles alternate with these suckers, in the 

 same row ; beyond these there is a triangular marginal group of 

 slender-pedicelled suckers (c), of about the same size ; other rows of 

 minute pedicelled suckers (or hooks) occupied the sub-median area, 

 between the marginal ones and the central line, which is indicated by 

 a strong white cord. The opposite margin of the club appears to have 

 borne several roAvs of small suckers, but this part is badly injured. A 

 band of minute papilla? (g'), apparently the remnants of suckers and 

 alternating connective tubercles, extends downward for more than 

 half the length of the tentacular-arm ; at first this band is like a 

 continuation of the connective suckers and tubercles on the margin 

 of the club, and the papillae are apparently in a single row, while the 

 surface near them is crossed by fine transverse grooves or furrows ; 

 but farther down the arms there may have been two or more rows of 

 suckers, which have been destroyed. 



The beak (fig. 1/) is somewhat compressed, with very acute man- 

 dibles. The upper mandible has the point long and regularly 

 incurved, with the cutting edge regularly arched, without a basal 

 notch, and forming, with the anterior edge, an obtuse angle. Lower 

 mandible, with a strongly incurved tip and regularly concave cutting 

 edge, having no basal notch, and only a slight tooth on the anterior 

 border, which forms a very obtuse angle with the cutting edge. 



Color mostly gone, but where still remaining, as on the back of 

 the tentacular club, it consists of minute purple chromatophores ; 

 inner surface of sessile arms purplish brown.
