290 MR. W. A. FORBES ON THE GREAT ANTEATER. [ Mar. 7, 
that having been found in Gervais’s specimen (perhaps in two), in 
Owen’s, and in one of mine for certain. 
I found the opening of the two other ducts exactly as described 
by Pouchet (J. ec. p. 89) and Gervais, one of these being dilated ter- 
minally, the dilatation receiving the other duct and opening by a 
single aperture into the mouth (vide Plate XV. fig. 3). 
At the point where the three submaxillary ducts of each side, 
coming from the three lobes of the gland, converge, and become united 
intimately by their walls to each other, they become surrounded by 
a bulb-like mass of muscular issue, the exact relations of which I 
shall describe below. But I could not perceive that this structure, 
which externally looks like a bulbous reservoir surrounded by a 
muscular coat, corresponded to any dilatation of the ducts which pass 
through it ; on the contrary, these seem to preserve a nearly uniform 
diameter throughout this part of their course, a condition correspond- 
ing to that described by Chatin in Tamandua. 
The terminal reservoirs, I may add, of the two pairs of submaxillary 
ducts lie just above the long thin median tendon of the genio-hyoid, 
the contraction of which muscle may possibly, by compressing the 
fluors of these reservoirs, aid in the ejaculation of the fluid contained 
in them. 
The stomach of Myrmecophaga generally resembles Prof. Owen’s 
figures and description ; but the thick pyloric pads are softer and 
more vascular, and the whole less gizzard-like, than I had been led 
to anticipate from his account. The gyriform folds of the mucous 
membrane of the cardiac part of the stomach, which quite resemble 
those of the stomach in many other animals, are, in particular, not 
happily represented in his fig. 1, pl. lil. 
The liver of both specimens agrees very well with Prof. Flower’s 
description of this viscus. Both caudate and Spigelian lobes are 
practically absent. 
As accurately described by Pouchet (‘Mémoires,’ pp. 191,192), the 
pancreatic duct ends in a vesicle, in the walls of which the hepatic 
duct runs for a little way and then opens into it, the vesicle then 
opening by a separate aperture into the duodenum. 
In the first (larger) specimen examined by me the intestines 
measured as follows :—small intestine 24 ft. 10 in., large intestine 2 ft. 
3% inches. The ceecum can hardly be said to exist as a separate 
part. The median longitudinal ridge of mucous membrane was 
continuous for the posterior 15 feet 3 inches of the small intestine, 
and reappeared above this at intervals in a less regular and less 
developed way. 
I could see no longitudinal folds of mucous membrane, such as 
are described by Owen, in the rectum, which, however, had dis- 
tinetly ¢ransverse ones, irregularly disposed in a gyriform way, well 
marked. 
The right lung is trilobed, with an azygos lobe superadded ; the 
left lung is bilobed, the lowest lobe in each lung being biggest. 
The kidneys are quite smooth externally: there are no distinct 
Malpighian pyramids, the tubules opening internally on a single
