right three inches in length, the left 2^ inches. The vasa defer- 

 entia connected them with the kidneys ; that of the right side 

 being four inches long, and that of the left 2^- inches. The kid- 

 neys were long, lead-colored bodies, divided into numerous lobules. 

 They have been aptly compared to a quantity of flat buttons, 

 strung together. The right kidney was seven inches long ; the 

 left six inches. The vas deferens passing over, and the ureter 

 issuing from the kidney, joined together, and, forming a strong 

 cord, opened together in a papilla on the inner surface of a blind 

 sac, about an inch below its upper extremity. The papillse, in 

 which the end of each side terminated, were side by side, about 

 half an inch apart. Below them, dissimilarity ceased. The 

 ureter of the right side was 21^ inches long; that of the left 

 eighteen inches. 



The sac itself alluded to, is the nearest approach to the urinary 

 bladder possessed by serpents ; it was 2J- inches long, and of the 

 capacity of a pullet's egg ; on its right side, near its lower part, 

 was the opening of the rectum ; and at its extremity, in the 

 centre, was the external anal opening, on each side of which 

 was seen the double penis with bifurcated extremities. The 

 penis forms, as it were, continuations of the sac, lying usually 

 in the tail of the animal. During sexual excitement it is re- 

 versed, like the fingers of a glove turned inside out, into the 

 sac, and extended through its anal opening. The specimen 

 showed it in this condition, having been distended with gelatine, 

 to show an approximation to its size, and the arrangement of the 

 inner (now outer) mucous membrane. The smooth membrane 

 of the sac extended down about half the length of the penis, 

 which was 4^ inches, where a fold commenced, which wound 

 in spirals to the extremities of the bifurcations. Each penis, or 

 each side of this double organ was bifurcated to the depth of 

 If inches. The urethra was not like the closed canal of the 

 higher animals, but a simple, straight, open groove running from 

 the sac to the spiral fold, where it was lost. 



The penis is retracted by long muscles, arising from the tail, 

 and inserted into the extremities of the bifurcations. 



Between the penis and the anus, on each side of the latter, 

 were two long, oat-shaped bodies ; these were the anal sebaceous
