LACERTILIA 



HEMIDACTYLUS SQUAMULATUS Tornier 



A single specimen taken at 8 o'clock in the evening in Dodoma 

 township as it was running across the road. An interesting pallid 

 variety in conformity with such a sandy habitat, the chainlike dorsal 

 markings are only faintly discernible. It has 7 upper and 6 lower 

 labials on the right, 8 upper and 6 lower on the left side. 



HEMIDACTYLUS MABOUIA (Moreau de Jonnts) 



HOUSE GECKO 



Native name. — Ikaka (Chigogo). 



Dodoma, Nzingi, Saranda, Manyoni, in houses or on rocky kopjes. 

 At Nzmgi two pairs of eggs were found adhering to the under sur- 

 face of a rock; in one pair were advanced embryos (25. v. 26). These 

 geckos were eaten by captive specimens of the spotted wood snake 

 {PMlothamnus semivariegatus) . 



LYGODACTYLUS GROTEI Sternfeld 



Dodoma, Bahi, Saranda, Manyoni, Mukwese, on doorposts, fences, 

 and tree trunks. This gecko replaces L. p. picturatus in the Dodoma 

 district but was nowhere very common, unless an exception is made 

 of the fence posts at Manyoni station. At Saranda only four were 

 seen in 10 days. 



The upper labials in this series range from 6 to 9, the lower labials 

 from 5 to 9; one Dodoma gecko has 7 praeanal pores, the maximum 

 hitherto being 6. 



PACHYDACTYLUS BIBRONII (Smith) 



A female from Dodoma taken on a wall of a room where H. ma- 

 houia was common. (19. vi. 26.). 



On the left side of the head in this specimen the nostril is pierced 

 between one large anterior and two small posterior nasals; on the 

 right side it is between a large anterior and three small posterior 

 scales. It is the largest example I have ever taken, measuring &J4 

 inches (81 + 75 mm.) from rostral to tip of tail. In its stomach 

 were seven large earwigs. A spotted wood snake (PMlothamnus 

 semivariegatus) was captured at Manyoni in the act of swallowing 

 one of these geckos. 



PACHYDACTYLUS TRIEDRUS (Boulenger) 



A male, taken on the wall of an outbuilding at Saranda, the same 

 wall being frequented by H. mahouia (7. vii. 26). 



It has the nostril pierced between the rostral, first labial, and four 

 small scales on the right side of the head; on the left side the labial,
