CEPHALOPODA. 
7 
tAVo large glands which envelope them in a viscid matter, and collect 
them into clusters. The testis of the male, placed like the ovary, 
communicates Avith a A'^as deferens which terminates in a fleshy penis, 
situated on the left of the anus. A bladder and prostate terminate 
there likeAA'ise. There is reason to believe that fecundation is 
effected by sprinkling, as is the case Avith most fishes. In the spaAvn- 
ing season the bladder contains a multitude of little filiform bodies, 
Avhich, by means of a pecAxliar mechanism, are ruptured the moment 
they reach the Avater, Avhere they move about Avith great rapidity, 
and diffuse a humour Avith AA’hich they arc filled. 
These animals are voracious and cruel ; possessed both of agility 
and numerous modes of seizing their prey, they destroy immense 
quantities of fish and Crustacea. Their flesh is eaten ; their ink is 
employed in painting, and the Indian, or China ink is supposed to be 
made from it.* 
The Cephalopoda comprise but a single order, which is divided 
into genera, according to the nature of the shell. 
Those Avhich have no external shell, according to Linnaeus, formed 
but the single genus, (a) 
Sepia, Lin* 
Which is noAV divided as folloAVS ; 
Octopus, Lam. — Polypus of the ancients.

* M. Ab. Remusat, however, ean fiud nothing in the authors of China which 
confirms this idea. 
M. de Blainville makes an order of them, which he calls the Ceyptodibran- 
CHITA. 
(a) Of course this genus in not included is theTestacea, although it is custom- 
ary for certain amateur naturalists to regard the cuttle-fish (sepia officinalis) as a shell- 
fish. In the system of Lamarck, the Cephalopoda constitute the fourth order of his 
Twelfth Class of Invertebrated Animals. He has arranged the genera, (some of 
which are noticed in the present section by Cuvier), in the folloAving manner, for 
which we are indebted to C. Dubois, Esq. 
TWELFTH CLASS. 
Mollusca. 
Order IV. — Cephalopodes. 
Character of the order : — Mantle of the animal in the form of a sack, containing 
the lower part of the body ; head projecting above the sack, crowned with arms 
not articulated, furnished with suckers, Avhich surround the mouth; tAvo sessile 
eyes ; two corneous mandibles at the mouth ; three hearts ; the sexes separated. 
They live in the sea, floating at large, attaching themselves to marine bodies at 
will : others only drag themselves along, by means of their arms, at the bottom of 
the water, or on its banks ; the greater part of these are generally secluded in the
