Plate XXXIV, figures 2-6. Plate XXXVII, figure 2. 
Larger and relatively stouter than HRossia 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 papilla, 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 XXXIV, fig. 6), 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 8 to 12 rows.
