MALAC0Z0A. CEPHALOPODA. SEPIINA. LOLIGO. 29 



reous shell, convex on botli faces, and terminated behind

1. Sepia officinalis. Common Cuttle. 



Body smooth; pedunculate arms very long; dorsal shell 

 elliptical, with a small slightly-curved point behind. 



A shell or bone of this species, found on the coast, by 

 Andrew Murray, Esq. Aberdeen, is in my possession. Dr. 

 Dyce also informs me that he has seen several bones of this 

 species. I have not, however, met with any myself, nor seen 

 the animal.

 denticulated horny margins, and two very long pedun-

1. Loligo vulgaris. Common Calmarg. 



Body, or visceral sac, subcylindrical, considerably depressed, 

 tapering behind to an obtuse point ; and having two large, 

 semirhomboidal flaps, or fins, attached to the dorsal region, 

 for two-thirds of the length of the body. Together, they 

 form a large, broadly rhomboidal expansion, which is attached 

 nearly in its whole length, leaving only the terminal portion 

 free. The dorsal aspect of the body is minutely punctate with 

 reddish-brown on a greyish-yellow ground ; the ventral aspect 

 yellowish- white. The mantle is free all round at its anterior 

 margin, which forms an obtuse point behind. The infundi- 

 bulum compressed, tapering, truncate. The head comparatively 

 small ; the eyes large, but with a rather small circular aperture, 

 of which the margins are rugose. The eight fleshy arms are 

 short, and taper to a minute, acuminate point ; the dorsal pair 

 shortest, the lateral dorsal, and the ventral pairs nearly equal,
