Description. — British Museum (one of Nos. 84. 3. 11. 1-5); Taiwan 

 fu, Formosa; presented by Formosa Museum. Vomerine teeth in 

 two shghtly oblique groups, their posterior edge barely extending 

 beyond the hinder edge of the choanse; snout rather long, the dis- 

 tance from the tip to eye longer than that from the latter point to 

 tympanum; lores concave; tympanum nearly as large as the eye; 

 interorbital space narrower than upper eyelid; first finger extending 

 slightly beyond second ; toes fully webbed ; inner metatarsal tubercle 

 rather large and strong; hind leg being carried forward the tibio- 

 tarsal joint reaches the anterior corner of the eye; heels not overlap- 

 ping; dorso-lateral glandular fold prominent, scarcely as wide as the 

 interorbital space; no longitudinal glandular ridges between the 

 dorso-lateral folds. Color (in alcohol): Upper parts with indistinct 

 blackish spots; underside distincth' mottled with dusky, especially 

 on throat, chest, and thighs; marblings on posterior aspect of thigh 

 confluent into an ill-defined band; a fairly distinct dusk^^^ band from 

 axilla to groin.

Variation. — Formosa specimens in British Museum do not have the 

 dorso-lateral fold as broad as specimens from Shanghai (Brit. Mus.), 

 in which it is fully as broad as the eyelid, while in the Formosan ones 

 it barely reaches the width of the interorbital space ; yet it is consid- 

 erably wider than in R. nigromaculata. There are no distinct glandu- 

 lar ridges between the folds. The vomerine teeth are between the 

 choana?, fully as far forward as in R. nigromaculata, while in the Shan- 

 hai specimens their position is somewhat more posterior. Boulenger ^

 the types. He is author of a Catalogue des Reptiles et Batraciens du Departement
