The adult male (U.S.N.M. No. 34392; northern Formosa) differs 

 chiefly in the presence of copulatory excrescences on the side of the 

 first fino;er, which is somewhat swollen at base, and by the two lare^e 

 external vocal sacs, located one on each side of the throat. 



The tadpoles of this species have been described and figured by 

 Mr. Stanley S. Flower from Siamese specimens.'^ His description, 

 drawn up from specimens obtained in June, 1897, at Ayuthia, Siam, 

 is herewith given in fidl. 



Length of body once and a half its width, rather more than half 

 length of tail; nostrils a little nearer to the eyes than to the end 

 of the snout ; eyes on the upper surface of the body, nearer the end of 

 the snout than the spiraculum, the distance between the eyes twice 

 the distance between the nostrils, and about equal to the width 

 of the mouth; spiraculum on the left side, directed backward and 

 upward, a little nearer the anus than the end of the snout, visible 

 from above and from below; anus opening on the right side. Tail 

 from three and one-half to four ti^mes as long as deep; acutely pointed; 

 upper erest convex, a little deeper than the lower, not extending on 

 to the back; depth of the muscular portion at its base about half 

 tlie greatest total depth. Mouth: the large powerful beak is entirely 

 black ; the upper mandible terminates in front in a long sharp tooth- 

 like prominence; the lower mandible is bicuspid, each "tooth" being 

 long and sharp; the lips are bordered with \evy short fleshy papillae; 

 inside the upper lip are five series of fine, black teeth; the first series 

 is uninterrupted by the individual teeth being "grouped with inter- 

 vals" al)out the center of the line; the remaining series are ])roadly 

 interrupted, the fifth being very short and diflicidt to distinguish; 

 the lower lip has also five series of teeth; the first is short ami unin- 

 terrupted, the second long and uninterrupted, the remainder broadly 

 interrupted and very short. Color (in life), above yellowish brown, 

 mottled with darker brown, a very distinct dark brown crescent-
