the glans is considerably elongated by the strong 
influx of blood into that structure. According to 
Voeltzkow (78) the penis in the Madagascar 
crocodile is 20 cm. in length. 
The clitoris of the sexually mature female 
crocodile is very much smaller than the penis of a 
male of the same size, but, according to Rathke, 
it varies greatly in size in different species. It is 
built on exactly the same plan as the penis. 
According to Bronn the clitoris as well as the 
penis projects from the cloaca, out through the 
anus, in the embryo of the crocodile; this was not 
observed by the present writer in the embryo of 
the Florida alligator, A. mississippiensis.
