MR. F. E. BEDDARD ON THE

tube arising from each testis, and each of these meets its fellow 

 of the opposite testis and forms with it a single duct ; this 

 occurs soon after each has emerged from the testis. 



The two ovaries are, like the testes, closely apposed in the 

 middle line, and as already mentioned each has a very large fat- 

 body attached to it anteriorly. The eggs were of considerable 

 size (some of them) and, as I should imagine, mature. But the 

 ovaries were not extensive as they are in the mature females 

 of other Batrachia. It may be therefore that the oviducts are 

 not as complicated in their coiling as they would have been had 

 the frog lived longer. In this specimen the oviducts were 

 as is represented in text-fig. 9 (p. 32). Anteriorly the funnel is 

 spoon-shaped with an elongated aperture on the lower surface.

The proximal section of the oviduct is narrow and straight in its 

 course. The thick- walled glandular region of the oviduct only 

 makes two loops, as is shown in the figure referred to. I am 

 inclined to think that the oviduct is after all mature or very 

 nearly so, for its walls are as thick as it seems likely they could 

 become. The glandular part opens into the distal and thin- 

 walled " uterus " which is flattened and strap-shaped. The two 

 tubes approach each other in the sam.e straight line behind the 

 kidneys, and form one tube running of course at right angles to 

 them towards its opening into the cloaca.
