THE GREAT ANTEATER. 299 



apertures alone), I found on the left side a single duct only, and on the 



right tivo, which united together at about the level of the articulation of 



the lower jaw. This specimen, however, had, it is to be remembered, 



extensive inflammation in these parts, which may possibly have effected 



an alteration in the relations and number of the ducts. It is pretty 



clear, however, that three pairs all together is the ordinary number of 



these ducts, that having been found in Gervais's specimen (perhaps in P. Z. S. 1882, 



two), in Owen's, and in one of mine for certain. p> 290> 



I found the opening of the two other ducts exactly as described by 

 Pouchet (1. c. p. 89) and Gervais, one of these being dilated terminally, 

 the dilatation receiving the other duct and opening by a single aperture 

 into the mouth (vide Plate VIII. 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 tissue, 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 corresponding to that described by Chatin in 

 Tamandua. 



The terminal reservoirs, 1 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 floors of 

 these reservoirs, aid in the ejaculation of the fluid contained in them. 



The stomach of MyrmecopTiaga 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, pi. lii. 



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 (' Memoires,' 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 caecum can hardly be said to exist as a separate part. The median 

 longitudinal ridge of mucous membrane was continuous for the posterior
