AN UNDESCRIBED MICROHYLA 

 By Thomas Barbour 



By a curious coincidence twice within a very short time 

 problems have arisen with respect to Microhyla, a genus which, 

 in general, seldom calls for comment in an American museum. 

 Dr. Malcolm Smith of Bangkok sent me some examples of 

 M. piilchra from Siam which enabled me to compare the types 

 of M. hainanensis with this species. I found the two related 

 but easily distinguishable. Just then Dr. A. G. Ruthven sent 

 for study a small suite of amphibians from Nanking, China, 

 and again Microhyla appeared. These specimens from China 

 had been considered the same as the Indian M. ornata by Bou- 

 lenger in 1882 (Cat. Batr. Sal. Brit. Mus., p. 165). So far as 

 I am aware this allocation has not been reconsidered. That 

 this little frog should have such a wide range seemed at once 

 most improbable and my receipt since of an example of ornata 

 taken in Pegu, from Dr. Boulenger, has enabled me to separate 

 the forms. To be sure Durheril and Bibron (Erp. Gen., 8, 

 1 84 1, p. 745) expressly state that the types of ornata came 

 from Malabar, India, collected by Dussumier, a long way from
