2 Description of four new Species of Chwrnsleon from 

 Madagascar. By Dr. A. Gunther, F.Z.S., Keeper of 

 tte Zoological Department, Britisli Museum. 



[Eeceived January 25, 1879.] 



(Plates XI.-XIII.) 



The Trustees of the British Museum have recently obtained by 

 purchase a small number of animals collected in the neighbourhood 

 of Antananarivo, the capital of Madagascar, a locality from which 

 we should scarcely have expected to receive many novelties. How- 

 ever, singularly enough, the five Chameeleons sent in this collection 

 prove to represent four species which appear to have escaped the 

 notice of previous collectors. 



Chameleon malthe, sp. nov. (Plate XI.) 



Snout (of the adult male) produced into a flat obtuse horn of 

 moderate length, grooved above and below, and covered with large 

 tubercles. Occipital region rather flat, angular but not pointed 

 behind, on each side with a broad flap, the two flaps being continuous 

 behind the occiput. Dorsal crest low, formed by short pointed 

 tubercles unequal in size. No gular or ventral median series of 

 tubercles. The round flat tubercles on the occiput and the occipital 

 flaps are unequal in size, but none very large, most nearly granular. 

 Along each side of the throat and on the limbs larger granules may 

 be seen scattered among the small ones ; but these larger granules 

 are almost wanting on the side of the body. Heel without spur or 

 prominence. Greenish yellow, with white upper lip, with a black 

 band running from the eye along each occipital ridge ; the portion 

 of the neck which is covered by the occipital flaps deep black. 



A single adult male, 9 inches long, the tail measuring exactly one 

 half. 



Chameleon brevicoenis, sp. nov. (Plate XII. fig. A.) 



Allied to C. cucullatus and C. monachus, but with the superciliary 

 ridge continued to the end of the occiput. 



The snout of the male is produced into a very short flat pro- 

 tuberance, concave above ; the raised canthus rostralis passing 

 uninterruptedly into the superciliary ridge, which is continued to the 

 occiput. Upper surface of the occipital region flat, without 

 prominent median crest. Occiput behind angular and pointed, but 

 not produced into a spine ; on each side a broad flap, the two flaps 

 being nearly entirely separated from each other by a deep notch.
