TYLOTOTRITON. 849 



the upper eyelid is large and glandular. Sixteen knob-like glands occur along the 

 side of the body, the first a short distance behind and above the axilla and on a 

 level with the paratoids. The last three are behind the leg when it is extended 

 at right angles to the body. The vertebral glandular ridge begins on a line with 

 the scroll-like extremities of the cranial crest and terminates at the root of the 

 tail. All obscure line of pores, larger than those of the rest of the body, from the 

 groin along the side to the under surface below the axilla.^ A series of pores behind 

 the angle of the mouth along the lateral, cranial ridge to the tip of the snout, 

 on the loreal region, behind the eye, along the mandible and internal to it. The 

 chin and throat are thickly covered with small smooth porous glandular tubercles 

 of nearly uniform size. The sides and upper parts of the body and tail are densely 

 covered with glandular tubercles (porous) of various sizes, irregularly distributed. 

 The ventral surface is transversely wrinkled and covered with very minute porous 

 glands, which scarcely project above the level of the skin. The upper margin of 

 the tail is sharp, commencing on a line with the last lateral knob ; the under 

 surface is rounded. There are numerous folds on the inner margin of the orifice 

 of the vent. The forearm extends the length of the fingers beyond the snout; 

 the le<>' reaches half-way to the axilla. Colour uniform blackish-brown ; paler on 

 the lips, snout, chin, throat, and under surface of the limbs, all of which have a 

 brownish-olive tinge. Under surface of the tail duU orange-yellow, fading into 

 lightish brown on the sides. 



The following are the measurements of eight specimens, males and females : —

This species is common in the high country of Yunnan, and since its discovery 

 there it has been found in the DarjeeUng Hills by Colonel Mainwaring.^ 



Vertebral column. — It is not very flexible, and it tapers so much to a point 

 at the tail that the last vertebra can be distinguished from the one before it only 

 by the aid of a hand lens. Throughout the trunk, the vertebrse, as in TJrodelu 

 generally, are opisthocoelous, but in some of the dorsal vertebrae the arrangement 

 is proccElian, and in the 15th caudal vertebra there was a ball at either end, the pro- 

 coelian arrangement occurring in the 16th and prevailing throughout the remainder 

 of the tail. In another individual the 25th caudal had a ball at either extremity 

 of the centrum, whilst the remaining vertebrae were procceHan. 



1 In certain conditions of the skin, these pores are very difficult to detect, but in other states they are gaping 

 and easily seen.
