424 BATRACHIA. 



because it is prior to Limnodytes, but also because it well expresses the natural characters of 

 these frogs. The form of the head and body and the length of the limbs are very similar to 

 those of Mana, whilst the more or less dilated extremities of the toes indicate a semiarboreal 

 life; they are very powerful leapers. The species are not very numerous, and have been 

 found hitherto in the East Indies, Western Polynesia, Madagascar, and West Africa. The 

 following are found in British India : —

Two glandular folds along each side of the trunk. 



The length of the foiu'th toe is two-thirds of that of the body . . . . H. macrodactyla, p. 424. 

 The length of the fourth toe is one-half of that of the body ; web ex- 

 tending to the end of the fifth and third toes H. erythrtea, p. 425. 



The length of the fourth toe is somewhat more than one-half of that of 



the body ; web not extending to the end of the fifth and third toes . H. macularia, p. 425. 



The length of the fourth toe is less than one-half of that of the body . H. malabarica, p. 426. 

 ** Only one glandular fold along each side of the back, none on the side of the belly. 



Disks of the fingers and toes well developed H. temporalis, p. 427. 



It is impossible to identify the following frogs, the descriptions by which they have been characterized 

 being perfectly useless : —

 Peninsula of India.

Habit very slender. Head much elongate, with flat crown, rather rounded canthus rostralis, 

 and long pointed muzzle ; upper jaw reaching far beyond the lower one ; loreal region 

 grooved ; nostril oval, lateral, just below the canthus rostralis, nearer the end of snout than 

 the eye. Eye moderate, prominent; tympanum large, nearly the width of the eye, just 

 above the angle of mouth. Limbs slender, with small, rather indistinct disks ; fingers quite 

 free, the third mucli the longest, first and second nearly equal in length, the fourth rather 

 longer ; subarticular tubercles moderate ; toes very long and slender, half-webbed, fourth 

 much the longest, two-thirds of the length of the body ; fifth longer than the third ; at the 

 base of the first finger a tubercle, rather smaller than the subarticular ones. Skin quite 

 smooth, only the hinder part of the under side of the thigh granular ; a glandular fold from 

 the back edge of the eye along the sides of the back ; another glandular fold from the angle 

 of the mouth along the sides of the belly. Cleft of mouth long ; tongue large, very long, 

 deeply notched behind ; palate very narrow ; interior nostrils moderate, eustachian tubes 

 rather larger ; vomerine teeth in two oblique series, convergent posteriorly, between the inner 

 nostrils. Above olive, with three parallel white stripes, one from the muzzle to the anus, 

 and the two others along the glandular folds, some brown spots between ; sides of body
