Snakes. 



It is a well known fact that snakes are not very nurae- 

 rous in most parts of East Africa, and this experience is not 

 contradicted by the results of this expedition, onJy the fol- 

 lowing specimens liaving been collected. 



Typhlops boulengeri Bocage? 1 specimen from the 

 eastern slopes of Mt. Elgon, altitude about 6500 f.; ^^^7 

 1920. With its very large praefrontal, wide rostral etc. this 

 specimen certainly resembles the species quoted very nearly, 

 but it may perhaps not be fully identical, because on one 

 side the praeocular touches the first and second Jabial, but 

 on the other the second and third. 28 scales round the body. 

 With only one variable specimen nothing more definite can 

 be said, but to state at least a close affinity to the species 

 written above. Professor Fr. Werner, who also has examined 

 it, has expressed the same opinion. Coll. H. Granvik. 



Boodon lineatus Dum. & Bibr. Kitosh country, south 

 of Mt. Elgon. Coll. G. Lindblom. 



Lycophidium capense A. Smith. Kitosh country, south 

 of Mt. Elgon. Coll. G. Lindblom. 



Dasypeltis scabra Lin. 1 sp. normally coloured from Soy 

 ^^5 1920, and another almost similar, but with partly con- 

 fluent spöts from the shore of a small lake, 6 miles north 

 of Eldoret, coll. H. Gr an vik. 1 sp. with complete cross- 

 bands (Boulenger's var. E.) from the Kitosh country, south 

 of Mt. Elgon, coll. G. Lindblom. 1 sp. without any markings 

 (Boulenger's var. F.) from the eastern slopes of Elgon, 6500 

 f., ^Ve 1920, coll. H. Granvik. These specimens are a further 

 proof of the great variability of this snake without any cor- 

 respondence to geographical distribution. It may, however, 

 be possible that the variety without markings is a forest 

 dweller, and that the spotted ones live in the open country. 



Psammophis sibilans Lin. 2 specimens from the neigh- 

 bourhood of Eldoret ^Ve & ^^ö 1920, coll. H. Granvik. 



Causus rhombeatus Lichtenst. A small specimen with 

 faint markings from the eastern slopes of Elgon, 6500 f., ^Vr,
