A single specimen from the Mubuku Valley, E. Ruwenzori, altitude 7000 feet. 
This species belongs to the section Siaphos Gray, which a few years ago was repre- 
sented by only a few Malayan and Australasian species. Five closely related species 
have now been described from Africa :— 
(1) L. kilimensis Stejneger (Proc. U.S. Nat. Mus. xiv. 1891, p. 405).—Digits 5—4, 
longest with 13-15 lamella below; ear-opening much larger than nostril; 24 scales 
round body. Kilimanjaro. 
(2) ZL. thomasi Tornier (Zool. Jahrb., Syst. xix. 1903, p. 175).—Digits 5—4, longest 
with 12 lamelle below; ear-opening not much larger than nostril; fronto-nasal fused 
with frontal; 24 scales round body. Nairobi. 
(3) L. aloysii-sabandie Peracca (Boll. Mus. Zool. Tor. xxii. 1907, no. 553).— 
Digits 5—5 (pollex rudimentary and clawless), longest with 14 lamelle below ; ear- 
opening not much larger than nostril; 22 scales round body. Mitiana and Toro.
