1916.] A. L. Massy: Cephalopoda of the Indian Museum. 207, 
conical cirrus on the posterior dorsal edge of each eye, with a 
smaller cirrus at the anterior dorsal edge. No nuchal constriction ; 
eyes not prominent. Arms about twice the length of the body, 
thick and muscular, tapering to fine points. Umbrella highest 
laterally, extending nearly one-third of the length of the arms, 
measuring 80 mm. between the dorsal and 70 mm. between the 
ventral pair; continued on outer margins of arms. Mantle- 
opening placed nearly at the ventral edge of eye and but little 
below it. Siphon conical, about half of its length projecting above 
level of eyes; funnel organ W-shaped, the median pads being 
very wide and touching one another throughout most of their 
length ; the lines forming the commencement and end of the ““ W” 
meet in a point and all the other angles are rounded. 
In the short arms, ocular cirri, and the deep scoop out occur- 
ring on the umbrella margin between dorsal arms, this resembles 
P. rugosus. It differs, however, in the long narrow body and the 
broad funnel organ to the specimens referred to P. rugosus in the 
present paper. Compared with an example of P. vulgaris from 
Plymouth !, this has a longer and narrower body, a wider mantle- 
opening, larger suckers, a higher umbrella dorsally, and a blunter 
apex to the siphon ; the latter also reaches higher above the eye 
than in P. vulgaris. The ventral mantle in the Plymouth specimen 
measures 85 mm. in length and 84 mm. in breadth, and the dis- 
tance from the end of the body to the eye is 100 mm.
