728 EEPTILIA. 



a considerable dilatation on the small intestine, but the anterior division of the left 

 lobe of the liver is large and widely invests it. The posterior section of the gland 

 fills up the lesser curvature posteriorly. The small intestine of a male, measuring 

 6 inches, was 29"'25 in length. The large intestine began by a decided and sudden 

 enlargement, and was 6 inches long. The liver is olive-brown and minutely punc- 

 tulated with black. The free lobule of the cystic division is occasionally uncon- 

 nected with the process that projects to the right from the inferior angle of the 

 left division of the liver, but the two are generally connected by a delicate band of 

 liver substance. The gall bladder usually perforates the outer side of the liver, 

 but is sometimes invested by it. The pancreas is narrow, band-like, compact but 

 thin, extending from close to the pyloric extremity to a little to the left of the 

 termination of the gall duct. The spleen is a reddish gland, in the usual Chelonian 

 position, 7 lines in length by 3 in width. The thymus is small, round and yellowish, 

 4 lines in diameter, slightly compressed from above downwards, situated anterior to 

 the base of the heart and lying below the origin of the great vessels. It is divided 

 into minute hexagonal lobules, which have almost completely degenerated into fat. 

 There are numerous lymphatics of a deep almost blackish colour, all about the 

 cardiac area, especially at the apex of the lungs and along the mesial line of the neck. 

 There is a very extensive cluster of large black inguinal glands closely applied over 

 the cloacal bladders, immediately external to the kidney and the extremity of the 

 lung which overlaps the anterior end of the kidney. The lungs are simple, being 

 very litle lobulated, the dorsal margin presenting a flat surface where it is applied to 

 the sides of the vertebral column, but without any lobulating ; a partial bilobino- of 

 the apex ; a projecting outer margin, contracting anteriorly and posteriorly ; and a 

 simple terminal sac-like lobule. The lungs are not very capacious. The glans-penis 

 and the clitoreal area are jet black ; the urethral folds are very distinct. The glans is 

 pointed, with the rosette consisting of three pairs of lobes on either side of the 

 termination of the urethral groove, the distal pair being connected together by a 

 transverse septum, the distal surface of which is traversed by the end of the 

 urethral groove. The mesial pair of lobes are very small. The clitoris consists of 

 two lobes forming a triangle with a distal apex, their extremities free proxi- 

 mally, a transverse fold connecting them with a pit below it, the ends of the 

 lobules having each a small filamentous process behind it, in reality the termina- 

 tion of the urethral fold of either side. The cloacal bladders are large, without 

 any villi, the walls being perfectly smooth when expanded, but rugose when con- 

 tracted. Prom their orifices a smooth tract runs along the cloaca to terminate 

 externally. 



This variety differs but slightly from the Indian form, but sufficiently to entitle 

 it to be indicated as a local race. In its habits also it appears to me to be less active. 



Like the Indian form, this Burmese variety is exclusively a vegetable-feeder, 

 and I observed that among other aquatic weeds it eat the common Vallisneria, 

 and, in confinement, plantains with avidity. It lays a number of oval eggs at one 

 time, burying them a little way underground.
