HERPETOLOGY OF JAPAN". 177 



do not extend backward beyond the median pair; granules on throat 

 immediately join the chin-shields; upper surface covered with uniform 

 granules (without trace of interspersed tubercles) those on vertex and 

 on supraocular region smaller, those on snout and lores larger; first 

 digit well-developed with a well-developed, free, and raised terminal 

 joint provided with a full-sized claw; six lamellae, of which three in 

 pairs, under first toe; ten lamellfe, of which six in pairs, under fourth 

 toe; throat covered with uniform granules, rest of under surface with 

 small, rounded, imbricate scales; a well-developed series of 13 pores 

 on each femur, not meeting on the middle of the abdomen, nor reach- 

 ing the knee joint; tail subcylindric, more depressed near base, taper- 

 ing, covered with uniform small scales of about the same size as the 

 large granules on the snout ; imderside of tail covered with a median 

 series of wide transversal plates. Color (in alcohol) above dark drab 

 gray a with obscure brown marblings ; scarcely discernible dark band 

 from lores through eyes, above ear-opening to side of neck, and a 

 similar one on parietal region ; underside whitish.

The adult female (U.S.N.M. No. 34211; Ishigaki Island, Riu Kiu; 

 Owston collection) differs in the absence of femoral pores. 



The most marked deviation, due to individual variation, from the 

 specimen described above is the presence of a second lateral pair of 

 chin-shields, smaller than the others, but well differentiated. 



Bemarks. — The specimens here recorded from Formosa and Riu Kiu 

 have not been compared with Indian specimens, but they agree so 

 completely with the published descriptions that I have no doubt 

 that they are correctly identified. The well-developed inner toe with 

 long terminal free phalanx and large claw, the series of 13 to 14 fem- 

 oral pores on each side interrupted on the middle of the abdomen, 

 and the tail devoid of tubercles indicate H. howringii beyond a doubt. 



The fact that this species has hitherto been recorded only from 

 India, Burma, and Tenasserim is of no weight now, since Dr. Jean Roux, 

 curator of the herpetological collection in the Basel Museum, informs 

 me that the //. coctsei recorded by Mueller in the catalogue of that 

 museum as from "Liolong and other localities in the province of 

 Canton," China, is in reality H. howringii, a fact of which he has 

 assured himself by repeated and careful examinations and com- 

 parisons with allied species.
