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.

 lar expansion.

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 oviduct is double. 



** Fins occurring near the tail, but not continued to its ex- 

 tremity. 



43. L. media. — Body long, fins elliptical, tail pointed.

 — Rare. 



Body slender, almost transparent, cylindrical ; arms with a double row of 

 suckers. Eyes large, blue. 



44. L. Sepiola. — Body short, fins thin and rounded, outline 

 of the tail semicircular. 



Sepia Sep. Linn. Syst. Penn. Brit. Zool. iv. 54. t. xxix. f. 46. — Rare. 

 Body scarcely exceeding an inch in length, and about |ds in breadth. 

 Arms with 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 Forth, 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. 



45. O. vulgaris. — Body smooth ; suckers a little remote, ar- 

 ranged in a double row. 



Sepia octopus, Sower. Brit. Misc. t. xliii.— Oct. vul. Lam. An. sans Vert. 

 vii. 657. 

 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 havino- 

 been sent to him from Dover by Mr Richard Phillips. It occurs, according 

 to the observations of Mr Neill and Dr Grant, in the Frith of Forth, not 

 unfrequentlv.
