414 BATRACHIA. 



absence of the humeral tubercles and of the occipital cross fold. A dark-brovra subtriangular 

 mark commences between the eyes, and extends nearly over the whole back. 



This frog has been found at Pinang, in Java and Sumatra, in Ceylon, and in the Philippine 

 Islands ; it inhabits woods in hilly countries. Females are larger and more numerous than 

 males ; one of the fonner measures 3^ inches, the hind limb being 4^ inches long. 



Megalophrys was founded on female specimens ; and Cantor appears to have been the first naturalist 

 who examined male individuals, but without being aware that the peculiarities observed by him were of 

 a sexual natui-e. At the period when my ' Catalogue of Batrachia SaUentia ' was published, Prof. Schlegel 

 acquainted me with a Sumatran frog, " similar to, but different from, MegaJophrys montana," which he 

 named Ceratophnjne nasuta. The name Ceratophrijne having a very different meaning from that of 

 Ceratophrys, I suppose that he intended to establish a new genus for this frog, which I characterized from 

 a small example received from Sir A. Smith. This example does not show any vomerine teeth, nor a web 

 between the hind toes, and therefore there was every reason to beUeve that it represented a genus different 

 from Megalophrys . 



However, when Schlegel published a diagnosis of this supposed new form, I saw that the " Ceratophryne " 

 of his MS. was in fact merely a misspelt form of the old generic name Ceratophrys, and that he never 

 intended to establish a new genus for the Sumatran frog, although he considered it as the type of a new 

 species. IMean while the British INIuseum received two old male indi^-iduals (one from Cantor's collection), 

 from which it became evident that they are pro^4ded ^rith vomerine teeth and with a verj- distinct inter- 

 digital membrane, and that they are only the male sex of Megalophrys montana. 



XENOPHRYS, Gthr. 



Fingers and toes tapering, free to the base. Lower jaw without pro- 

 minent apophyses ; the internal openings of the nostrils and eustachian 

 tubes small ; tympanum rather small and inconspicuous. No parotoids. 

 The transverse processes of the sacral vertebra much dilated. Vomer with 

 two separate prominences, which are apparently toothless. The upper eye- 

 lid is well developed, broad, with a sharp, prominent edge, but without 

 appendages. 



This genus is founded on a single species from the Himalayas. 



Xenophrys monticola. (Plate XXVI. fig. H.) 



Similar in habit to Megalophrys montana. Head broad, depressed, rather short ; snout 

 rounded, with its extremity prominent and obliquely truncated, so that it considerably over- 

 reaches the cleft of the mouth; canthus rostralis sharp; loreal region slightly concave; 

 nostril below the canthus rostralis, in the middle between the eye and the end of the snout.
