'below the sinus of tlie seventh sternite (VII. st.) is narrowev 

 in tripeciinata, and the lobe above the sinus longer than the lower 

 lobe, the sinus therefore being much deeper in that species. 

 The eighth tergite is divided by an apical incision into a broad 

 setose upper lobe and a narrower and naked lower lobe in both 

 species. The upper lobe, however, bears more bristles in trvpec- 

 tinata both on the outer and inner surfaces, and the bristles 

 placed further proximad on the eighth tergite are also more 

 numerous in tripectinata. The eighth sternite, on the conti'ary, 

 has more bristles at the apex in the new species.

I. »SoME Notes upon the Frog Megalophris 

 ( Leptobrachjum) fe^jl. 



Of this species* living examples have been recently, and are 

 at the moment, exhibited in the Society's Gardens. The Frog was 

 later described by Mr. G. A. Boulengerf as of the genus Lepto- 

 brachium, but originally J referred to the genus Megalophrys, 

 to which all the Pelobatidse belonging to the former genera 

 Megcdophrys, Xenophrys, and LeptobrachmTn are now § by him 

 referred. In dealing with certain points in the anatomy of 

 M. fece^ I shall have occasion to refer to the mutual likenesses 

 and unlikenesses between this and other species of the family 

 to which I have already paid some attention i|. 



The external characters have been so fully described by 

 Mr. Boulenger in the several papers quoted below, that little 

 remains to be f-aid under this heading. There is, however, one 

 point to which I may refer. In ^e?C[\ng\N\th. Xenophrys inonticola 

 and other forms, I have described *[\ and figured a glandular patch 

 upon the thigh which is very characteristic of these Frogs. I can 

 find no trace of this structure in Megalophrys fece ; and it is thus 



* The specimens were, as I understand, identified by Mr. G. A. Boulenger.
