Descriptions of several neiv species of Cuttle-fish. 

 Bead March 20, 1821. By C. A. Lesueur. 



Having observed many species of the class Ce- 

 phalopoda, and being desirous to arrange them agree- 

 ably to the new systematic distribution of this class, 

 which Dr. Leach has published, (in the Journal de 

 Physique for May, 1818,) I experienced much diffi- 

 culty in disposing of one of my species. This spe- 

 cies corresponds with those of his first order Octopo- 

 da, by having eight arms, similar to those of the 

 Eledona, &c. and with those of his second order, by 

 the form, of the body, and the position of the fin, 

 being similar to those of the species of the Genus 

 Loligo. With these characters it ought to form an 

 intermediate section, betiueen these two orders. 



Dr. Leach has appropriated the name of Octo- 

 poda to those animals of this class, that have 

 eight arms, and a body destitute of a fin ; and the 

 name of Decapoda to such as are furnished with ten 

 arms, and with fins which margin the body (or sac) 

 entirely, or partially. 



The latter, constituting his second order, are in 

 part referred to a family which he names Sepiidea 

 and which is composed of the Genera Sepia and
