This small species resembles the next iu general proportions, but is 

 nearer the last in the rndimental condition of the limbs.

 from the orbit posteriorly ; a gular fold. Costal grooves extending to 

 vertebral line, but not curved forwards there, as in Hemidactylium 

 scutatum ; extending across abdomen. Body slightly compressed. 

 The tail as stout as the body at the base, subquadrate in section, be- 

 coming compressed at the tip ; strongly annulate; not swollen. Inner 

 digits on both feet minute. Vomerine series well developed ; parasphe- 

 noidals as in the last.

The general proportions of this salamander are not unlike those of 

 Hemidactiilium scutatum Tsch. It differs from this iu its uniform color 

 above and below, and in some more important points. Upper surfaces 

 dark brown, lower brownish-yellow. Vertebrce and costal folds between 

 axilla and groin eighteen, the latter not prolonged dorsally, as in the 

 H. scutatum. Head oval, elongate; lip rounded; e.yes large, prominent 

 longitudinal diameter longer than length of muzzle. Muzzle to hu- 

 merus half length from latter to groin. Tongue elonjf^ate, oval; para- 

 sphenoid teeth approaching near to the short oblique series of vomer-
