424 A. E. Verrill — North American Cephalopods. 



tQx of largest suckers of sessile arms, '1o inch. The arms appear very- 

 stout, especially at base, and not very unequal in size. In form they 

 agree well with those already described from previous examples. 

 The ventral arms have the inner face broader than on the other 

 arms, and the two crests along the outer angles are well developed. 

 The suckers, so far as preserved, have the same characters as in the 

 former examples ; the more proximal of those on the ventral arms 

 are closer together in a longitudinal direction, but the rows are 

 f artlier apart than on the other arms. The mandibles are dai'k brown, 

 the tooth on the anterior alar edge of the lower mandible is large 

 and prominent. 



The color, which is partially preserved, especially on the arms and 

 on the ventral surface of the body, agrees pretty nearly with that of 

 Omiiiastrephes^ consisting of small purplish brown chroniatophores, 

 more or less thickly scattered over the surface. The back had a 

 bleached appearance, as if the creature had laid upon the shore or 

 floated at the surface, with the back exposed, for some time after 

 death. 



Owing to the mutilation of the tips of the ventral arms, hectocoty- 

 lization could not have been detected, if it had originally existed. 

 The sex, therefore, could not be determined without cutting open the 

 mantle. By everting the edge of the mantle, as far as possible, I 

 could see, owing to insuflicient light, only the tips of the gills, which 

 are situated rather far back, but the reproductive organs could not 

 be seen.
