AKT. 25 CHINESE AMPHIBIANS AND REPTILES STEJNEGER 53 



These specimens show the usual variability of the species. The 

 Szechwan specimen has 26 scale rows, the Peking one 30; the two 

 from Nanking have 28. In other respects these two specimens which 

 are of the same size dilFer more from each other than from the 

 northern and western ones. Xo. 65095 is quite normal, the limbs 

 being small, when adpressed to the side not meeting by the dis- 

 tance from eye to ear. In No. 65522 the tips of the longest digits 

 meet, the feet being much better developed: in addition the inter- 

 nasal is divided by a regular suture.

postnasal; fronto-nasal much broader than long, broadly in contact 

 with frontal; prefrontals small, smaller than fronto-parietals, 

 widely separated; frontal undivided, very long, though not quite 

 twice as long as its distance from tip of snout, angularlj^ emarginate 

 laterally by the anterior supraocular, the anterior portion with the 

 longer sides converging posteriorly, the posterior portion with the 

 longer sides slightly diverging posteriorly, in contact laterally with 

 first and second supraoculars, and behind with fronto-parietals 

 and interparietal; three large supraoculars, second larger than first 

 which is larger than third; first and second supraoculars in contact 

 with frontal, third in contact with fronto-parietals and parietals; 

 fronto-parietals, not in contact with each other, much smaller than 

 third supraocular; interparietal much longer than wide, lozenge- 

 shaped, in contact with frontal ; parietals rather large, much larger
