situation those described in the human stomach, but upon a 
larger scale and more obvious to the naked eye. Beyond this 
part, the internal membrane of the cardiac portion has one 
uniformly smooth surface studded over with glands, parti- 
cularly along the great curvature. The pyloric portion has a 
number of glands of a different structure more minute than 
those of the cardiac portion ; these are placed principally along 
the surface of the small arch, and are continued on to the 
pylorus, where there is a zone of glands surrounding the ter- 
mination of the stomach, and the origin of the duodenum. 
In this animal these glandular structures are very conspi- 
cuous, which are not to be detected in the domesticated car- 
nivorous animals. Vide Plate XII. fig. 1. 
XVIII. The Vampyre Bat. 
The animal from which the stomach was taken was nine 
inches long, the extent of its wings 36 inches. 
The oesophagus swells out before it enters the general 
cavity, and that dilatation from its internal structure appears 
to belong to the stomach, as there is no contraction, or distinct 
orifice beyond it. To the left of the oesophagus there are 
two dilatations with a neck between them ; the furthest of 
these has a smooth surface and the coats are very thin ; in the 
other there are several deep longitudinal rugae, some of which 
are continued into similar rugae, or bands in the dilated por- 
tion of the oesophagus. This portion of the stomach has 
more the appearance of an appendix than belonging to the 
general canal. There are six rugae or bands in the oesopha- 
geal portion, four of which are continued towards the pylorus, 
giving a direction to the food in that course. After the stomach
