49. Bitis arietans, Merr. — Between Matagoi and Lugh ; a 

 single young specimen.

BATRACHIA. 



1. Rana ornata, Ptrs. — Between Matagoi and Lugh; several 

 young specimens. Comia Pass; several tadpoles at various stages 

 of development. 



In these tadpoles the mouth is essentially of the Ranine type ; 

 the edge of the upper lip is dentate , whilst that of the lower 

 is papillate; there is no second row of upper labial teeth; the 

 lower labial teeth form two uninterrupted rows ; the beak is 

 black ; the papillae are long and conical, especially one at each 

 side of each lip, which may almost be termed a barbel. 



2. Rana mascareniensis, D. and B. — Lugh and between Ma- 

 tagoi and Lugh; several specimens. 



3. Chiromantis petersii, Blgr. — Between Matagoi and Lugh ; 

 a single specimen. 



4. Cassina obscura, Blgr. — Comia Pass; a single specimen. 



5. Bufo regularis , Reuss. — Brava , Matagoi , Lugh , Web ; 

 several specimens. 



6. Bufo taitanus, Ptrs. — Matagoi and between Matagoi and 

 Lugh ; several specimens. 



This species was described by Peters in 1878 from a single 

 specimen obtained by Hildebrandt at Taita together with the 

 type of Rana ornata. It is interesting to find examples of the 

 two species again associated in this collection. A few months ago 

 the British Museum received a single male specimen from Lake 

 Tanganyika, collected and presented by Mr. W. H. Nutt. 



Peters's description is very incomplete. The following cha- 

 racters may be added : — Interorbital space at least as broad 

 as the upper eyelid; tympanum two thirds the diameter of the 

 eye, usually quite hidden, sometimes slightly distinct; first and
