poulpe, is reserved for lodging the palmated part of the two 
great tentacula, which are united by this part into a small glo- 
bular mass, forming a vault, under which the eggs find a place 
of protection, and perhaps also the heat necessary for their de- 
velopment. These eggs are attached to the duplicatures of the 
palmated membranes, by small peduncles, and form altogether a 
cluster. M. de Ferussac proves, that it is really the constructor 
and the lawful proprietor of this beautiful shell. This opinion 
has long been adopted by Messrs Cuvier and Dumeril, who 
were appointed by the Institute to examine M. de Ferussac’s 
memoir, a memoir to which the Academy has accorded its ap- 
probation. M. Dumeril relates a fact which has escaped M. de 
Ferussac’s notice, namely, thatM. Duvernoy has long ago point- 
ed out the existence of the shell upon the embryos in the eggs. 
Very lately an extract of a memoir of Poli on this animal, was 
read before the Poyal Society of Naples. In this memoir, after 
a short introduction, he describes, in a circumstantial manner, its 
shell, and points out the varieties of it w 7 hich occur. He then 
traces the history of this animal, indicates its mode of feeding, 
and describes its manner of sailing. He had an opportunity of 
observing at his ease, and in a state of life, an individual caught 
upon the shores of Fausilippe, which was sent to him by order 
of the King. He saw it lay its eggs, and observed the daily 
development of the embryo of each of them, in which he found 
the shell already partially formed. M. Poli refutes the asser- 
tion of Aristotle, that the animal is not connected with its shell 
by any muscle. In a second memoir, this experienced naturalist 
intends to treat of the distinctive characters of the argonaut, and 
to give a full description of it. The two memoirs are accom- 
panied with very beautiful plates.— Bullet. Univers. May 1825. 
S3. On the Bisulcated Horse , the Equus bisulcus of Molina . — 
None of the animals described by Molina in his account of Chili, 
excited greater attention in the zoological world, than that men- 
tioned under the name Plorse with divided hoofs. He says, that 
although it bears a striking resemblance to the horse, yet its 
hoofs are divided. The teeth, he farther remarks, are large, and 
in position like those of the horse. Shape, size, hair, and co- 
lour of the body like that of the ass ; the ears resemble those of 
the horse, and it wants the black dorsal cross. Head, mouth.
