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. Jcilimensis Stejneger (Proc. U.S. Nat. Mus. xiv. 1891, p. 405). — Digits 5 — 5, 

 longest with 13-15 lamellae below; ear-opening much larger than nostril; 24 scales 

 round body. Kilimanjaro. 



(2) L. thomasi Tornier (Zool. Jahrb., Syst. xix. 1903, p. 175). — Digits 5 — 5, longest 

 with 12 lamellse below ; ear-opening not much larger than nostril ; fronto-nasal fused 

 with frontal ; 24 scales round body. Nairobi. 



(3) L. aloysii-sahandice Peracca (Boll. Mus. Zool. Tor. xxii. 1007, no. 653). — 

 Digits 5 — 5 (pollex rudimentary and clawless), longest with 14 lamellse below ; ear- 

 opening not much larger than nostril ; 22 scales round body. Mitiana and Toro.
