418 MK. G. A. BOULENGER ON ORIENTAL [Apr. 28, 



This frog was indicated, rather than described, by Jerdon in 

 1870, from specimens collected by him at Darjeeling and in the 

 Khasi Hills, now preserved in the British and Indian Museums. 

 Further allusion to it was made soon after by J. Anderson, 

 who regarded it however as the adult of Giinther's Xenoplirys 

 monticola. After examining about 50 specimens, measuring 

 32-94 millim. from snout to vent, I am convinced that Jerdon was 

 right. Most of the specimens in the Indian Museum are from 

 Cherrapunji, Khasi Hills. I have examined specimens from the 

 Karin Hills, in Upper Burma, and from the Man Son Mts., 

 Tonkin (3000-4000 feet). If I am right in regarding Anderson's 

 Ixalus lateralis as a young M. gigas, the range of the species 

 extends to Western Yunnan. 



I regret the name chosen by Jerdon cannot be used for this 

 species, as there is an earlier Megalophrys gigas Blyth, 1854, 

 which is, however, a synonyra of Rana Uehigii Gthr, I have 

 therefore proposed the new name Megalophrys onajor.
