EAST AFRICAN REPTILES AND AMPHIBIANS 95 



adpressed hindlimb in gariepensis (including granti) reaches from 

 the tympanum to the eye while in these regularis it reaches from the 

 eye to the end of the snout or just beyond. 



It is difficult to imagine such extremely warty and spinose types as 

 Nos. 40921 and 42028 representing the same species as the aforemen- 

 tioned smooth specimens, but individuals intermediate in wartiness 

 between these two extremes and more typical regularis may be found 

 in Nos. 22095, 41093, 41313, 42050, 42988. It is interesting to note, 

 however, that all the extremely warty toads come from the vicinity 

 of Mount Kenya. 



In size the series ranges from a 14-mm. toad (No. 41151 taken 

 between Mount Kenya and Fort Hall, October, 1909) and a 108-mm. 

 female (No. 41679 from the Southern Guaso Nyiro).

I have just examined the 60-mm. dried toad which was taken on 

 Mount Kinangop, Kenya Colony (P. M. No. 24-48) and which was 

 referred to B. latifrons by Monsieur Angel. B. latifrons was long 

 ago referred to the synonymy of B. polycercus and I have compared 

 the Kinangop toad with Cameroon examples of the latter in the col- 

 lection of the Museum of Comparative Zoology and consider that 

 they represent one species. 



Monsieur Angel's record is, therefore, the first of the occurrence 

 of this very spinose toad in East Africa and makes one more inter- 

 esting addition to the list of Cameroon species occurring on isolated 

 mountain peaks in the eastern part of the continent.

Two of these toads (Nos. 63527-8) lack the pair of spots in the 

 lumbar region which are so characteristic of the species. It is occa- 

 sionally absent in specimens from Tanganyika Territory. The same 

 animals, which I presume are males, have minute, black spines scat- 

 tered over the whole dorsal surface as far forward as the occipital 

 region. On referring to the pair of Kilosa toads taken in embrace,*^ 

 I observe that these spines are well developed in the male, scarcely 

 distinguishable in the female. The largest of the three Kafue River 

 toads (No. 63528) measures 83 mm.
