EAST AFRICAN LIZARDS. 



157 



Lygosoma FERRANDII (BlgT.). 



Blgr. Ann. Mus. Gen. (2) xviii. 1898, p. 718. 



Seven specimens in all ; six of these from Longicio "VYest have 

 been examined by Mr. Bonlenger and referred to this species. 

 The measurements are as follows, though almost all the speci- 

 mens have reproduced tails : — 



Dodoma. Female 91*36 mm. Longido. Male 56*46 mm. 



Longido. Male 90*40 mm. ,, 53*50 mm. 



,, 62*62 mm. ,, 43*37 mm. 



,, ,, 59*59 mm. 



The lis mm. specimen was caught under rather unusual 

 conditions. After a night of heavy rain I was summoned at 

 6 A.M. to the tent of one of the sergeants to see a small snake 

 {Lycophidium jacJcsoni) labouring to swallow this Skink. It w^as 

 the only snake of this species captured. Another man told me 

 that he had killed a snake with tiny legs in his blankets ; on the 

 battered remains being produced it proved to be this species. 

 The other specimens were all obtained under stones. These 

 Longido specimens are of a uniform nut-brown colour above, 

 creamy or yellowish beneath. 



Ablepharus boutoni var. peroxii (Coct.). 

 Blgr. Cat. Liz. iii. 1887, p. 347. 



Seventy-one specimens collected at Mombasa, Dar-es-Salaam, 

 and Lumbo. This little lizard has adopted a marine life ; it is a 

 remarkable sight to t>ee it running over the rocks, which a 

 moment before were washed by waves ; for company it has the 

 peculiar fish F eriophthalmus and crabs of many species. It flies 

 before the incoming wave and presuma^bly manages to avoid a 

 wetting. It seeks refuge when pursued in the many crevices of 

 the rock. It is extremely agile and difficult to capture. 



Measurements of the largest specimens from each locality : — 



Mombasa. Male 3 inches (42*35 mm.). Tail regenerated. 



„ Female 4J ,, (43*60 mm.). 



Dar-es-Salaam. Male 44 „ (45*70 mm.). 



,, Female 4| (47*65 mm.). 



Lumbo. Male 4| „ (48*62 mm. ). Tail regenerated. 



Female 3| ,, (50*46 mm.). „ 



Coloration very variable. Some Lumbo specimens, both young 

 and old, almost black, but underlying markings usually dis- 

 tinguishable on close examination. Greenish or olive-bronze ; 

 two light lateral (almost dorsal) stripes start at nostril. Upper 

 surface of tail marked with white dots in lines ; these were absent 

 on regenerated tails. The Dar-es-Salaam specimens were much 

 more brow^n or coppery, and with the markings more distinct 

 than ill the Lumbo specimens. 



Five females collected at Dar-es-Salaam (ll.iv. 18) had each
