BATRACHIA. 



Examples of four species of Tree Frog are included in this section 

 of the collection, but unfortunately ail the specimens of two of 

 these are so small and so much shrivelled that I have found it

 the latest British Museum Catalogue. One of the remaining 

 species is described as new under the name of Ilyla laacgreyori.
