CHELONIA. 769 



to the right of the bend of the stomach, the viscus is tubular, as in allied tortoises. 

 Its walls in the latter situation are thin, but in all the remaining portion to the right 

 they are 0"-35 thick. The smaU intestine preserves one calibre throughout, and 

 its mucous coat is thrown into longitudinal folds, finer but of the same general 

 character as those on the oesophagus, with three or four very fine wavy folds 

 between each. It measures seven feet three inches in the largest adult, the 

 measurements of which I have given, and is considerably longer than in B. baska, 

 B. lineata, &c. There is a distinct pyriform cajcum about two inches long when 

 contracted, and about one inch in diameter. The large intestine is tliree feet 

 long, and it is very different from the large intestine of B. baska, B. lineata, and 

 B. duvaucelli, in describing two sigmoid curves instead of one. The liver in- 

 vests the stomach to a much greater extent than in either B. baska or B. lineata. 

 The gall bladder, which is of considerable size, hes in a concavity on the left 

 side of the gland, and is transverse to the body from the dorsal to the ventral surface, 

 bent slightly to the right, its apex appearing thi^ough the liver substance from the 

 right side of the cavity in which the viscus is placed. The gaU duct is eight inches 

 long before it reaches the intestine, and, at this distance, its presence is indicated, in 

 the mucous coat of the intestine, by an almost cartilaginous process of the wall, and 

 beyond this it runs under the mucous coat for l"-40 and then opens by a mmute 

 orifice, although the tube has considerable capacity. The bile has a rather rich 

 dark-green colour, and the Hver is much Hghter-colom-ed than in other tortoises I 

 have examined. 



The chtoris of this species consists of an outer rosette of four lobes in pau's, with 

 a terminal pointed lobe, the inner rosette being small, consisting of one pair of lobes 

 and an azygos terminal lobe traversed by the urinal canal, i, e., the same type as in 

 B. baska and B. lineata. The peritoneal canal having the same length as in these 

 species and apparently opening near the base of the glans. 



The cloacal bladders are large and covered internally with long villi, which, 

 however, do not extend on to the cloacal walls, as in B. baska. The longitudinal 

 folds guarding the ovario-urinary chamber are full and broad, and when drawn 

 asunder are seen to be connected by a transverse constriction, or short fold, 

 below which there is a small pit. The ureters open immediately below the orifice of 

 the oviducts, at the extremity of a short downward prolongation of the folded border 

 of this orifice. The ureter is short (1"50 inch), but of considerable calibre, and 

 its narrow orifice is defined by a crescentic fold on its upper margin which prevents 

 regurgitation of the fluid. 



The oviduct is capacious, and, in the individual before me, the ovary was 

 18 inches long, and had numerous ova ; the contents of the larger ova were a bright 

 yellow grumous substance. The oviduct measured 3 feet 4 inches. The first foot 

 from the cloacal opening had its inner surface of a decided pinkish hue, and was 

 thrown into numerous transverse, but interrupted fine folds, while all the remaining 

 portion of the tube was of a pale greyish, almost faint bluish-white tint. The 

 peritoneal attachments of the tube were weU defined internally and gave rise to its
