AND ACCOUNT OF A NEW SPECIES OF SEPIOLA. 8] 
arise from muscular fasciculi close to the anterior ganglion, between it and the orbit 
on each side, and external to the brachial disk which forms the eight arms, so that 
they are analogous in position to those of Gasteropoda and other Mollusca. 
From the commencement of the esophagus! at the root of the tongue to its termina- 
tion in the gizzard, it is narrow, cylindrical, without the usual longitudinal plice of its 
mucous coat, and does not perceptibly dilate to form a crop; its parietes are thin, 
smooth, and transparent. The inferior pair of salivary glands? are in contact with the 
esophagus, of considerable size, and placed behind the upper margin of the two lobes of 
the liver. The gizzard’, of a lengthened form, with distinct longitudinal muscular bands 
strengthening its parietes, measures, when slightly inflated, about three lines in length 
and two lines in breadth. It is extended in a longitudinal direction, and its muscular 
fasciculi are chiefly confined to its middle portion: it is situate on the right side, im- 
mediately above the ovarium, and close to the branchial heart of that side. From the 
direction followed by the wsophagus downwards behind the liver and towards the right 
side, and the course taken by the intestine upwards in front of the liver on the left side, 
the gizzard in the Cephalopoda lies a little behind the spiral stomach on its right side, 
and it is placed a little lower in the sac. The spiral stomach‘ of the Sepiola opens 
from the gizzard by a passage wider than the esophagus ; and they are so continuous, 
that the digested contents of the stomachs pass freely to and fro, from the one cavity 
to the other, on the slightest pressure or motion of these sacs. This stomach is marked 
with transverse plice of its parietes, producing the usual puckered appearance of its sur- 
face and its internal folds. It forms only a semicircular curve, terminating abruptly 
in a rounded shut extremity, and is about half the size of the first stomach. This cavity 
receives the hepatic and pancreatic secretions, as in most of the known genera of Naked 
Cephalopods. 'The intestine passes very wide and almost straight from the back part of 
the spiral stomach over the fore part of the liver and ink bag, and terminates in the 
anus, immediately above the ink bag, within the widely expanded base of the funnel. 
The anus*, situate between the two longitudinal muscles above described, opens by a 
circular aperture with thin loose parietes, and has two very small tentacular folds ex- 
tending from its sides, as in most other genera of this class. 
The liver ®, consisting of two lengthened lobes rounded above and tapering below, is 
of a light yellow colour and very soft texture, and extends along the back of this short 
animal from immediately under the orbits to the ovarium. The two lobes are united 
at their upper and back part, and their component ceca are filled with a turbid yellow- 
ish-white fluid. The hepatic ducts? come out from the lower part of the liver, one from 
near the inferior apex of each lobe, and unite into one at a short distance from their 
termination in the spiral stomach. Their oblique orifice in the spiral stomach is pro- 
vided with the usual prominent valvular lips, which can be traced along the intestine
