CERCOPITHECID.E 725 
Their digestive organs are much modified, the stomach attaining 
an extraordinary complexity, which may be described as follows. 
An ordinary stomach must be supposed to be immensely elongated, 
and gradually tapering from the 
cardiac end to a very prolonged, 
narrow, pyloric extremity. Then 
twolongitudinal muscular bands, 
corresponding in situation to the 
greater and lesser curvatures of 
anordinary stomach—the former 
commencing just below the fun- 
dus, and the latter at the cardiac 
orifice, and both proceeding \ 
towards the pylorus—are de- 
veloped, so as to pucker up the 
cavity into a number of pouches, 
exactly on the same principle as 
the human colon is puckered up 
by its three longitudinal bands. 
These pouches are largest and 
most strongly marked at the 
wesophageal end, and becoming 
less and less distinct, quite cease 
several inches before the pylorus 
is reached, the last part of the 
organ being a simple smooth- 
walled tube. The fundus, or 
cardiac end of the stomach, is 
formed by a single large sac, 
slightly constricted on its under 
surface by the prolongation of ; 
the inferior longitudinal band, Fia. 348.—Lateral view OF the skull and palatal

or that corresponding to the (rom De Blainville.) 
great curvature. The cesophagus 
enters into the upper part of the left, or pyloric end of this sac, or 
rather at the point of junction between it and the second (also a 
very large) sacculus. Furthermore, the whole of this elongated 
sacculated organ is, by the brevity, as it were, of the lesser curva- 
ture, coiled upon itself in an irregularly spiral manner, so that 
when in situ the pylorus comes to be placed very near the esophageal 
entrance.
