EAST AFRICAN REPTILES AND AMPHIBIANS 111 



I am not aware of any earlier record of ^. minutus from the Zambezi 

 than this specimen taken by H. C. Raven in 1919; that it occurs 

 on the southern bank of the river we know from two examples from 

 the Victoria Falls (M. C. Z. 10989-90) taken on February 28, 1925, 

 by W. Sprague Brooks, who definitely says that they were taken on 

 the southern side. A. minutus should therefore be added to the 

 South African fauna, its known range being from Somaliland to the 

 Zambezi. This is an extensive distribution for so small a frog but is 

 paralleled, or rather excelled, by that of Plirynobatrachus natalensis. 



Two of the Mount Gargues frogs were found to have been feeding 

 on termites. 



The Mount Sagalla series are heavily infested on the posterior 

 aspect of the thighs (occasionally on the belly also) by a small oval 

 parasite, a larval mite, lying close to the skin but not embedded in 

 the limb tissues. 



[ARTHROLEPTIS SCHEBENI Nieden] 



Arthroleptis schebeni Nieden, 1913, Sitzber. Ges. Naturf. Freunde Berlin, p. 451. 

 (Klein Nauas, Southwest Africa.) 



Under the above name. Angel ^° has recorded a small frog (P. M. 

 No. 24-20) from Mount Kinangop, Aberdare Range, Kenya Colony. 

 Having aflorded me the opportunity of examining it I have arrived 

 at the conclusion that it is specifically distinct from schebeni and 

 apparently represents an undescribed species. On zoogeographical 

 grounds one would scarcely expect a species from the arid regions of 

 the southwest to be conspecific with one from the moist mountainous 

 highlands of the northeast. 



The Kinangop frog difl'ers from schebeni in that its interorbital 

 space is as wide, instead of "wider than," the upper eyelid; its toes 

 are one-third webbed not "entirely free of web"; there is no tubercle 

 at the base of the fourth toe, though there is a clear white spot rather 

 like one; it is not, however, raised, let alone pointed. 



It agrees in many points; the tympanum is hidden; there is 

 -certainly no tarsal tubercle; the tarso-metatarsal articulation reaches 

 the anterior base of the forearm which may, or may not, be the case 

 with schebeni. The skin is smooth. Color above is brownish with a 

 light dorsal line; beneath it is white vermiculated with brownish on 

 the extreme flanks and on the lower sides of the limbs; soles of feet 

 brownish dotted with white, toes lighter. Length from snout to 

 vent 18 mm. In a very poor state of preservation.
