OMMATOSTREPHID A. 39 
the club has also a great number of small suckers, whilst a few 
nearly sessile ones are scattered on the inner surface of the 
peduncle. Most of these had no denticulations on the rings. 
The beak has a wide, strong tooth about the middle of the edge 
of the upper mandible, and a much narrower notch on the outer 
mandible, on each side. These specimens are now in the Museum 
of the Royal Society, at Dublin. 
Several very large cephalopods have been stranded on the coasts 
of Newfoundiand and Labrador, within the past few years; most 
of them have been well described by Prof. A. BE. Verrill. 
STEENSTRUPIA, Kirk, 1882. Large, body comparatively slender, 
cylindrical, very slightly swollen in the middle; caudal fin small, 
rhomboidal, lateral; head long and narrow; eyes large, round ; 
sessile arms small, all of same size; suckers stalked; internal 
shell lanceolate, with a hollow conical apex. S. Stockii, Kirk 
New Zealand. 
PLECTOTEUTHIS, Owen, 1881. Folded squid. Suckers upon a 
relatively broader flattened tract than in Ommatostrephes; back 
or dorsal side of the arms also with a broad tract, flanked by a 
thin fold of the integument extending the length of the arm on 
either side. 
Described from a single gigantic arm preserved in the British 
Museum. ‘The suckers are as in Ommatostrephes. The ventral 
arms of Architeuthis are similarly fringed, and it is very doubtful 
whether the characters given by Owen are sufliciently distinctive 
even for a subgenus. P. grandis, Qwen (xxiv, 17). 
MASTIGOTEUTHIS, Verrill. Body elongated, tapering to a point, 
confluent with the caudal fin posteriorly. Caudal fin very large 
and broad, rhomboidal, occupying about half the length of the 
body. Mantle fastened to the base of the siphon by an ovate, 
ear-shaped elevated cartilage on each side, fitting into corres- 
ponding deep, circumscribed pits on the base of the siphon. 
Siphon with a bilabiate aperture, an internal valve, and a pair of 
dorsal bridles. KHyes large, with round pupils; lids free, thin, 
apparently with a very smallanterior sinus. Arms very unequal, 
the ventral ones much the longest. Suckers small, in two regular 
rows. Tentacular arms lone and round, tapering to the “tips, 
shaped like a whip-lash, without any distinct club; the distal 
portion is covered nearly all around with exceedingly numerous 
and minute suckers, which have only a very narrow, naked 
line along the outside. Pen narrow and bicostate anteriorly, 
very slender in the middle; posteriorly much larger, with a long 
tubular cone. 
This remarkable squid is distinguished by the character of the 
tentacular arms and suckers, the pen, the connective cartilages, 
and simple eyelids. JZ. Agassizii, Verrill (xxiv, 15, 16).
