108 F. Stoliczka — On Indian Batrachia. [June, 



two thirds* the diameter of the ej^e, and by yellow spots on black marbled 

 ground on the hinder side of the femora. The two last mentioned characters 

 certainly do not hold good in a comparison with true maculatus, and as I 

 have observed in adult males of the last species a tolerably distinct interrupt- 

 ed crest on the occiput, I cannot but doubt that Peters' Polyp, liscutiger is 

 really specifically distinct from P. maculatus. 



16. POLTPEDATES MAEMOEATUS, Blyth. 

 (Anderson, Proc. Z. S., 1871, p. 209.) 



Full grown males are barely more than half the size of the females, 

 they have a glandular fold indicated at each side of the back, the thumb 

 very much swollen, and the upper pale coloration is much tinged with violet- 

 bluish, with numerous, interspersed yellowish white dots and darker, more or 

 less confluent, spots. The general colom' in the female is yellowish green with 

 more or less confluent bluish brown spots. Lower side of femora tinged with 

 pale yellowish red. 



P. marmoratus is common in the Sikkim valleys at elevations between 

 1000 and 3000 feet ; it is equally common in the Khasi hills, but apparently 

 rarer in Pegu. I have seen only young specimens from the latter country. 

 According to Jerdon it is identical with Giinther's P. Afgliana,'\ which is, 

 however, stated to possess a smooth skin. 



17. Khacophoeijs maximus, Griinther. 

 Comp. Anderson in Proc. Z. S., 1871, p 210. 



I have repeatedly observed this frog at the base of the Sikkim hills, 

 about Pankabari, between 1000 and 2000 feet, and I do not think that it 

 ranges much higher, except in the damp and warm valleys. It lives near 

 the watercourses of streams in very dense jungle. 



Skin smooth above, on the side of the anterior part of the body, about 

 the shoulders and behind the eye, and on the upper side of the femora and 

 tibiae, finely, but almost spinulously, granular, particularly in adult males ; 

 belly and lower side of femora densely covered with subequal, more or less 

 flattened coarse warts ; a glandular fold runs from behind the eye to above 

 the shoulder and then to the side of the belly behind the shoulder ; the 

 tympanum is usually not very distinct, and rarely wider than half of the 

 longer diameter of the eye. 



Colour during life ; body and limbs bright green above, violet below, palest 

 on the lower chest and belly, brightest on the throat and particularly on the 

 side of the belly, where usually some dark more or less confluent spots are 

 traceable ; these are also to be noticed on the lower side of the hind limbs. 



* In adult muculatus the tympanum is often barely as large. 



f For which Cope proposes the generic name Amoloi^s, characterised as having 

 *no dorsal -lateral glandular dermal folds.' (See Nat. Hist. Review, V, 1865, p. 117.)
