This skink is specifically identical with what I have been calling 

 comorensis hitherto. In body length it is larger than any of the series 

 of maculilahris listed below, being 230 (91 + 139) mm.; it also differs 

 from them in possessing 36 scale rows (though we know that true 

 Cameroon maculilahris have 33 to 36 scale rows, while East African 

 examples more usually have 30) ; the dorsals are septemcarinate and 

 it has 5 supraciharies; its praefrontals are separated and the anterior 

 loreal is excluded from contact with the first labial.

These are onl}'^ tentatively referred to maculilahris, for it occurs to 

 me that they are more nearly related to comorensis than to maculila- 

 hris, at the same time they are undoubtedly identical with what 

 Boulenger called maculilahris from Ruwenzori, for they have been 

 compared with one of his series from that mountain; with the excep- 

 tion of the Kampala skink they are apparently the same as Stenfeld's 

 M. maculilahris major from the Central Lake region and agree with 

 specimens in the Museum of Comparative Zoology from Mutea on 

 the White Nile; Rutshuru and Bumba, Belgian Congo, and Sao
