352 A. E. Verrill — North American Cephalopods. 



their bases by a short Aveb, which is absent between the ventral 

 arms ; the dorsals are shortest ; tlie third pair the longest and largest ; 

 the second pair and ventrals about equal in length. Suckers, (PI. 

 XLVI, fig. 5, «), numerous, sub-globular, not very small, the margin 

 bordered with several rows of minute scales; near the base of the 

 arms they are biserial, tliere being usually four to six thus arranged 

 in each row ; then, along the rest of the length of the arms they 

 become more crowded and form about four rows, those in the two 

 middle rows alternating with those in the marginal rows ; toward the 

 tip they become very small and crowded, especially on the dorsal and 

 ventral arms. The number of suckers varies Avith age, but on one of 

 the laro-er specimens tliey were as follows : on eacli dorsal arm, sixty ; 

 on one of second pair, tifty-live ; of third pair, fifty-three; of ventral, 

 sixty-five. In this specimen ( ? ), the tliird arm of the right side and 

 ventral arm of left side were abruptly terminated (accidentally), 

 while the others were tapered to acute points. The tentacular arms, 

 in preserved specimens, will extend back to the posterior end of the 

 body; the naked portion is smooth, somewhat triquetral, with the outer 

 side convex and the angles rounded ; terminal portion widening rather 

 abruptly, long ovate-lanceolate, curved and gradually tapered to the 

 tip • the sucker-bearing portion is bordered by a wide membrane on the 

 upper and a narrow one on the lower margin ; the suckers (Plate 

 XLVI, fig. 5, h, c,), are very small, sub-globular, crowded in about 

 eight to ten rows in the widest portion. 



The males differ from the females in the relatively greater size of 

 the suckers on the middle of the lateral and ventral arms, those 

 toward the tips becoming somewhat abruptly smaller, while in the 

 female they decrease more gradually. 



Color, pinkish, thickly spotted with purplish brown above, paler 

 and more sparsely spotted beneath and on the outside of the long 

 arms • the inner surface of the arms and front edge of the mantle are 



pale.
