Rossia sublevis Verrill. — (Smooth bob-tailed squid.)

Plate XXXIV, figures 2-6. Plate XXXVII, figure 2. 



Larger and relatively stouter than Rossia hyatti, with the fins larger 

 and placed farther forward, the front edge of the large, free lobe reach- 

 ing nearly to the edge of the mantle. Head large and broad ; eyes large. 

 Sessile arms more slender and less unequal in size than in the preced- 

 ing, and with the suckers in two regular rows throughout the whole 

 length. Anterior edge of the mantle scarcely sinuous, advancing but 

 little dorsally. Upper surface of the body and head nearly smooth, but 

 in the larger specimens, especially in the males, usually with a few 

 very small whitish papillae, most numerous near the front edge of the 

 mantle. Color, nearly as in the preceding species. The male differs 

 from the female in having larger suckers on the lateral arms of both 

 pairs (Plate XXXIY, fig. G), and to a less extent on the ventral arms. 



The large suckers are oblong, with a groove or constriction around 

 the middle, the part below the groove larger than that above it; the 

 aperture is small, ovate, with a smooth rim ; their pedicels are short and 

 laterally attached. In the female the corresponding suckers are not 

 only smaller, but are differently shaped, the basal portion being smaller 

 than the upper portion. The suckers of the tentacular arms are very 

 numerous, minute, shallow, cup-shaped, with oblique rims and slender 

 pedicels ; they are nearly equal and appear to form S to 12 rows.
