shaped mark above each nostril; below white, purplish gray about 

 the chin and throat; tail yellow, mottled with brown, a horizontal 

 dark line along the median line of the basal third of the muscular 

 portion; iris golden. Total length 52 mm.; length of body 18.5; 

 width of body 12.5; length of tail 33.5; depth of tail 9. 



Variation. — This is the largest species of frog in that part of the 

 world which is included in the present work. The female described 

 above is small. Ariother Formosan specimen in our collection 

 (U.S.N.M. No. 34390), measures 131 mm. from snout to vent, and 

 specimens from other localities as large as 165 mm. are on record. 

 The males are smaller, our largest from Formosa (U.S.N.M. No. 

 34392) measuring only 94 nun. in total length. The hind legs appear 

 also to be shorter, inasmuch as the tibio-tarsal articulation does not 

 reach even the tympanum. The ground color in our specimens is 

 not brownish but olive, and the color in life is probably some shade 

 of the latter tint. 



Remarks. — Specimens from Borneo, w^hich I had the privilege of 

 examining in British Museum, have the vomerine groups of teeth more 

 oblique and separated from the choanal by a space fadly equal to 

 that between the two patches. I can not, therefore, agree in regard- 

 ing Rana scMueteri Werner as a synonym. Chinese specimens in our 

 museum (U.S.N.M. No. 7435; Hongkong; W. Stimpson, collector) 

 agree with the Formosan specimens as described. 



Hahitat. — Widely distrilnited from India and Ceylon through Burma 

 and Pegu to the Malay peninsula and archipelago," Celebes, and the 

 Philippine Islands; eastward it extends into southern China, where 

 it occurs as far as Ningpo and Shanghai. 



Its occurrence in Formosa is attested by four female specimens in 

 British Museum, collected at various times by Sw^nhoe, Dickson, and 

 Collingwood, and by three specimens, male and female, in the United 

 States National Museum from northern Formosa, obtained through 

 Mr. A. Owston.
