contractions and dilatations, as in other species of the class. The feet are 
nearly of the same length as the body, and covered with suckers towards their 
distal extremity. There is no eye-lid. The bone is elliptical, elongated, 
produced at the upper extremity, a groove along the middle, the edges thin. 
The appendage to the stomach is straight, and the oviduct is single.

The feet are shorter than the body, and covered with suckers nearly to 
the base. The two arms between the feet, and the two dorsal ones, are the 
smallest. The skin surrounding the mouth unconnected with the two feet 
and the two dorsal arms, though united at the base between them. Suckers 
in two rows. A duplicature of the skin round the eye forming an eyelid. 
The dorsal plate or bone is narrow, thin, expanded at both ends, and strength- 
ened by one central and two marginal ribs. The appendage to the stomach 
is spiral, and the ovdduct is double. 
Fins occurring near the tail, but not continued to its ex-- 
tremity.

Body scarcely exceeding an inch in length, and about |ds in breadth. 
Arms Avith two rows of pedunculated suckers ; those on the feet small, and 
confined to an oblong disc near the extremity — This seems to be a rare 
species. Pennant obtained it from the Flintshire coast. A specimen in 
my possession was found in the Frith of F orth, and presented to me by Mr 
Chalmers, surgeon, Kirkcaldy, and another specimen has subsequently been 
found in the Forth by Dr Grant. It was observed by Captain Parry in Da- 
vis’ Straits. 
Gen. XII. OCTOPUS. — Suckers sessile.

ranged in a double row.

Body oblong, tinged with brown. Arms nearly six times the length of 
the body, and furnished with about two 240 suckers. Oviduct double ; mar- 
gin of the anus simple. — This species is recorded by Mr Sowerby as having 
been sent to hirh from Dover by Mr Eichard Phillips. It occurs, according 
to the observations of Mr Neill and Dr Grant, in the Frith of Forth, not 
unfrequently.
