put in the same bottle as thc first they crawlcd around and were probably excited. 

 They became thcn dark. In alcohol both darkened, but the one more than fche other. 

 This Chaniöeleon appears to be very widely distributed in South, Bast, and 

 West Africa.

A specimen from Meru borna 3 % 1911 has a total length of about 275 mm. 



This species has been reported from two different localities in East Africa. 

 Originally it was described from Shire highlands, Nyassaland by Gunther, låter it 

 was recorded from Ogaden, Somaliland by Böttger. Meru borna is of interest as 

 being intermediate between these two very distant places.

A specimen of this variety was caught on Kenia 2b ls 1911 at an altitude of 

 about 2,500 m. 



This specimen has a well developed casque so that the distance from its ex- 

 tremity to the commissure of the mouth is longer than the distance from the latter 

 point to the tip of the snout. The rostral tubercles are also well developed. 



This Chameleon is known from Leikipia, Mau, Elgon, and Kenia. It is thus 

 an inhabitant of the mountain forests of the interiör of East Africa. 



Chamaeleon affinis Ruppell. — Plate 1, Fig. 3. 

 Blgr.: Cat. Lizards B. M. III, p. 461. 



Just within the börder of the primeval forest on the eastern slopes of Kenia, 

 one days march from Embu borna a Chamseleon was caught 26 /i 1911. It was a very 

 dark specimen without any white ventral stripe but otherwise it agrees with Bou- 

 lenger's diagnose of this species. On the other hand, there are in Werner's de- 

 scription of the same species 1 some words which cannot be applied to the present 

 specimen. Werner says: > Tern porall eiste schief nach hinten aufsteigend, den Lateral- 

 kamm etwa halbwegs zwischen Orbita und Helmspitze erreichend; das von beiden 



Cristen gebildete Dreieck mit höckrigen Schuppen ausgefiillt; • . » There is no 



such »triangulär field covered with tubercular scales > in the present specimen. As 

 this is not mentioned in Boulenger's diagnose I do not know whether it is an 

 essential characteristic or not. Should the presence of such a triangulär field with 

 tubercular scales prove to be characteristic of the true Ch. affinis, the present speci- 

 men ought to be regarded as a separate geographic race, Ch. affinis embuensis. re-
