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 {I. c. 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 

 sball 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 He just above the long thin median tendon of the geuio-hyoid, 

 the contraction of which muscle may possibly, by compressing the 

 floors of these reservoirs, aid in the ejaculation of the fluid contained 

 in them. 



The stomach of Myrmecophaga generally resembles Prof. Owen's 

 figures and descri[)tion ; 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 reseinble 

 those of the stomach in many other animals, are, in particular, not 

 happily represented in his fig. 1, pi. lii. 



The liver of both specimens agrees very well with Prof. Flower's 

 description of this viscus. Both caudate and Sjiigelian lobes are 

 practically absent. 



As accurately described by Pouchet (' Memoires,' pp. 1 9 1 , 1 92), 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. 

 2>k inches. The csecum 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- 

 tinctly transverse ones, irregularly disposed in a gyriform way, well 

 marked. 



Tl»e 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 : tiiere are no distinct 

 Malpighian pyramids, the tubules opening internally ou a single
