No distinct elements can be detected with certainty, but 

 there is a large and conspicuous perforation in the region 

 that may be taken to represent the hypercoracoid *. The 

 radials are not differentiated. 



Fharyngeal hones. — The pharyngeal bones resemble tliose 

 of Mastacemhelas, and bear numerous sharply pointed 

 recurved teeth. 



Caudal Jin. — We have nothing to add to Whitehouse's 

 description (op. cit.) of the caudal fin, except to point out 

 that the upper part of the hypural projects further than the 

 lower, giving the tail a slightly heterocercal form, as is well 

 shown in the figure in Whitehouse's paper and on plate i. of 

 Annandale's account of the hshes of the Inle Lake [op. cit.). 



Chaudhuria caudata. Alimentary canal. 



Alimentary canal (fig. 4). — The alimentary canal consists 

 of a straight or almost straight tube, extending from the 

 mouth to the anus and without pyloric appendages. The 

 oesophagus, which is narrowly funnel-shaped, passes gradu- 

 ally into the stomach, which is long and tubular. The 

 pylorus is a still narrower and very much shorter tube, and 

 opens into the intestine directly without curvature Avhen 

 empty ; but when it is dilated, owing to the presence of the 

 remains of food or of parasites, a slight curvature can be 

 detected. The intestine is quite straight, and is swollen 

 towards the end to form a rectum. The anus is surrounded 

 by a series of small tubular glands. The liver is very large, 

 and so is the gall-bladder. 



Air-bladder. — The air-bladder resembles that of Masta- 

 cembelus, being a long tubular structure lying immediately 

 below the vertebral column. The walls of the posterior 

 extremity in some specimens are thickened for a short 

 distance, and this region is marked off in such individuals by 

 a narrow transverse constriction. In others, however, it is 

 apparently homogeneous in structure and not constricted. 

 In our preparations w^e have not been able to find any 

 definite connection between the bladder and the auditory 

 apparatus. 



Gonads. — Most of the specimens Ave have dissected are
