East-African Chaineleons. 73 



difference between tliem is no greater than between indivitluals 

 of the South-African Ch. jnimilus. 



The third species described by Steindachner, Ch. tavet- 

 ensis, is the same as Stejnegcr's Ch. Abbott i. The library of 

 tlie Natural-History Museum having received a copy of the 

 latter author's paper on Sept. 2, and the number of the 

 Vienna ' Anzeiger ' containing Dr. Steindachner's diagnosis 

 on June 22, I regard C/i. tavetensis as having priority, 

 and it is under that name that I shall describe a female 

 specimen which has recently been presented to the British 

 Museum by Mr. Keith Anstruther, who obtained it at Taveta 

 on the 30th June last. 



Chamceleon tavetensis^ Stdr., ? . 



Casque feebly raised posteriorly, with a mere indication of 

 a parietal crest ; the distance between the commissure of the 

 mouth and the extremity of the casque equals tlie distance 

 between the former point and the nostril ; canthus rostralis 

 with a series of conical tubercles ; the rostral appendages 

 replaced by a slight swelling in front of the nostril. Body 

 covered with subequal, rather large, flat granules, some of 

 which may be regarded as slightly enlarged " tubercles ; " no 

 crests. Tail longer than head and body. Olive-grey ; a 

 pair of white lines along the middle of the posterior part of 

 the belly.

Chamceleon Fischeri, Reichenow, which is only known to 

 me from the description, differs from Ch. tavetensis in the 

 much more strongly compressed rostral appendages and the 

 presence of a crest on the anterior part of tlie back. 



Before concluding I have a few remarks to make on some 

 other Reptiles described by Dr. Steindachner in the same 

 paper. 



1. Tetragonosoma effrene^ Cant. — Dr. Steindachner, who has 

 overlooked Stoliczka's description (Journ. As. Soc. 

 Beng. xxxix. 1870, p. 203, pL xi. fig. 3), is mistaken 

 in believing the Lycodon described by me as L. atro-
