REPTILES AND AMPHIBIANS FROM LAKE REGION 791 
Central Lake region at a lower level than rudis. Insufficient allowance has been 
made for a reasonable amount of variation in these creatures where different 
vegetational and climatic environments may occur in close proximity. 
The races of bitaeniatus which Sternfeld proposed do not seem to be well 
characterized, but it is almost impossible to place them in the synonymy with- 
out examining the types. It is to be hoped that workers in Berlin will re- 
investigate these with a view to settling their identity. 
Some of the forms from this region, if races of bitaeniatus, would be as fol- 
lows: — 
Ch. b. elliott Giinther, 1895. Foot of Ruwenzori, Uganda. 
Ch. b. rudis Boulenger, 1906. Mubuku Valley, Ruwenzori, Uganda. 
Ch. b. bergeri Sternfeld, 1912. Sirgoit, Kenya Colony. Based on 1 male. 
Ch. b. graueri Sternfeld, 1912. Bugoie & Rugege Forests. 
Ch. b. torniert Sternfeld, 1912. Lendu Plateau and Banjeroberg, West of Lake Albert. 
Ch. b. bequaerti de Witte, 1922. Beni, Belgian Congo. 
Others have been described from Massai-land, Kilimanjaro, and Kenia. 
Chamaeleon johnstoni Boulenger 
Ch. grauert Steindachner, 1911, Anz. Ak. Wiss., Wien, p. 177 (West of Lake Tanganyika). 
Ch. johnston affinis Sternfeld, 1912, Ergebn. Deutsch. Zentralafr. Exp. 1907-1908. v. IV, 2, p. 260 
(Northwest bank of Lake Tanganyika). 
Ch, tturiensis Schmidt, 1919, Bull. Am. Mus. Nat. Hist., XX XIX, Art. ii, pp. 589-593. (Medje, 
Belgian Congo). 
1 (M.C.Z. 24861) Kisenyi, North shore of Lake Kivu. 
18 (M.C.Z. 24862-79) Lulenga, B.C. 
In addition to the above we have as comparative material a cotype of 
C. johnstont from Mt. Ruwenzori, a paratype of Ch. grauert from Northwest 
Lake Tanganyika, and three paratypes of Ch. ituriensts from Medje. Stern- 
feld’s species was based on a single female and a young one and his type locality 
is practically that of Ch. grauert. 
In describing C. ituriensts Schmidt hinted that it might be synonymous 
with Ch. 7. affinis and he since informs us that it is undoubtedly a synonym 
of C. johnstont. The present fine series collected by Dr. Bequaert enables us 
to bridge over all those small differences on which the alleged Ch. graweri and 
Ch. j. affinis were based, the latter was differentiated on account of the large 
plate-like lateral scales, but in our series these scales are to be found in every 
stage of development, or almost undifferentiated. 
AMPHIBIA 
Xenopus laevis (Peters) 
2 (M.C.Z. 14616-7) Lake Bunyoni, Uganda. 
Both half grown measuring 34 mm. from snout to vent. First fingers al- 
most equal to fourth, shorter than second which is shorter than the third. 
Much spotted and reticulated beneath. 
Bufo regularis regularis Reuss 
3 juv. (M.C.Z. 14618-20) Kabale, Uganda. 
4 (M.C.Z. 14621-24) Lulenga, B.C. iii. 27.
