The specimen which I am about to describe was put into my 

 hands by my teacher, Prof. Howes, he having received it through 

 the generosity of D"^- P. H. Carpenter of Eton College, in whose la- 

 boratory it was first dissected. 



The external characters shewed it to be a young male of Ran a 

 temp or aria. It came to hand in November, and from the study 

 of its anatomy, and on comparison with normal individuals of known 

 age, I conclude that it was in its first year. 



The genitalia are remarkable for the great size of the right 

 testis (t.r.) and for the complete ditferentiation of the uterine segment 

 of the oviducts, especially that of the left side (ut.). The right testis 

 is 12 mm. long, 4 to 5 mm broad and 3 to 5 mm. thick — on the whole 

 exceptionally large for the size of the animal. Antero- externally it 

 bears a small pigmented excrescence or ovarian portion. The corpus 

 adiposum of this side is exceptionally small, consisting of but two 

 delicate lobes, one of which bifurcates.

 Its external half is differentiated into a densely pigmented ovarian 

 portion, substantially identical with that of the specimen described by
