tliat Xeno2)hrys nnd L&ptohrachiuni are not nearer to each other 

 than any other two. M'ith the addition of some further cha- 

 racteI^s these genera may be described as on the following pages. 



The genus Xenojylivys will be thus characterised : — 

 Sliin with no conspicuous indurations. Aggregations of glands 

 present on thighs. Tympanum fairly conspicuous. Vertehrce 

 proccelous ; sacral vertebra free from coccyx. Omostemum rudi- 

 mentary., cartilaginous ; xiphistermim ossified, ending in au ex- 

 panded cartilaginous plate. IJyoid with anterior processes inclined 

 towards each other ; thyrohyals hotorglass-sha^yed with long cartila- 

 ginous epij^hysis separating the second and third. p)etrohyoidei pos- 

 teriores. Right lung supp)orted for more than half its length hy 

 ptihno-hepatic ligament. Sternum long in proportion to hody-length. 

 Pectoralis poste^'ior arising from trhole of sternum. Suhmaxillaris 

 fleshy throughout, with only a fine median tendinous raphe. Suh- 

 hyoideus not very distinct from suhmaxillaris and slender. Larynx 

 tvith long sep)arate hypopharyngeal p)rocesses and short bronchial 

 hoop. 



The following definition will indicate the chief characteis of 

 Leptobrachium : — 



Skin with no conspncuous indurations. Aggregations of glands 

 present on thighs. Tympanum fairly consjncuous. Yertebrce pro- 

 ccelous; sacral vertebra free from coccyx. Omostemum rudimentary, 

 cartilaginous ; xiphistermim ossified, ending in an expanded car- 

 tilaginous plate. Hyoidj toith anterior processes strictly parallel, 

 and not inclined toward,s each other ; thyrohyals rod,-like, without 

 a laterally directed epiphysis. Lung supported for nearly its entire 

 length by pulmo-hepatic ligament. Sternum short in proportion to 

 hody-length. Pectoralis piosterior reduced in size. Submaxillaris 

 with extensive tendinous centre. Suhhyoideus very distinct and 

 large. Larynx with no hypopharyngeal processes of cricoids, which 

 remain separate. 



Megalophrys has the following characters : — 



Shin with no conspicuous indurations ; with many tubercles. 

 Aggregations of glands p)resent on thighs. Tympanum fairly con- 

 spicuous. Vertehrce ojnsthocalous ; scleral vertebra free from coccyx. 

 Omostemum rudimentary ; xiphisteriium ossified, ending in a not 

 expanded cartilaginous plate. Hyoicl with anterior processes 

 inclined towards each other ; thyrohyals hour glass -shaped with 

 long cartilaginous epiphysis lying behind p)osterior petrohyoidean 

 muscle. Right lung supported for its entire length by pulmo- 

 hepatic ligament. Sternum long in p)roportion to body-length. 

 Pectorcdis posterior reduced in length of origin. Submaxillaris 

 'with extensive tendinous centre. Suhhyoideus distinct and large. 

 Larynx as in Xenophrys. 



There remains the Frog which I have hitherto referred to 

 under the name of Megcdop)hrys nasuta. There is no doubt that
