3. Report on a Collection of Reptiles and Batrachians sent 

 by Emin Pasha from Monbuttu, Upper Congo. By 

 Dr. A. GiJNTHER, F.R.S. 



[Eeceived January 10, 1888.] 

 The specimens, 27 in number, belong to the following species : — 



TORTOISES. 



1. Pelomedusa subrufa, Lac. 



LIZARDS. 



2. Varanus niloticus, L. — Two young specimens. 



3. Hemidactylus brookii. Gray. 



4. Lygodactylus gtjtturalis, Socage. 



5. Chameleon senegalensis, var. l^vigata. Gray. — Three 

 specimens. Although I adopt Mr. Boulenger's view that C. leevigatus 

 of Gray should not be specifically distinguished from G. senegalensis, 

 still the former may be readily recognized by its conspicuously finer 

 granulation of the skin, and especially the srnaller size of the scutella 

 of the side of the head. The type of O. Icevigatus came from the 

 Soudan ; and the three specimens sent by Emin Pasha agree in the 

 characters mentioned with this geographically not very remote form 

 of Chamseleon. 



SNAKES. 



6. Typhlops eschrichtii, Schleg. — Three specimens. 



7. Typhlops liberiensis. Hallow. — Two specimens.
