EAST AFRICAN REPTILES AND AMPHIBIANS 69 



Thome Island, West Africa. I hope shortly to have the opportunity 

 of examining the type of maculilabris and topotypic specimens of 

 comorensis; until this is done the identification had better stand. 

 The largest specimen measures 261 (85 + 176) mm.; in body length, 

 however, it is surpassed by the 90 mm. Kaimosi skink, whose tail is 

 damaged; the range in body length is from 72 to 90 mm.; scale 

 rows 30 to 34, with dorsals possessing from 5 to 7 keels; supraciliaries 

 number from 4 to 6, the same skink often possessing an azygous 

 arrangement while others are normal, thus No. 63422 has 6 and 4, No. 

 63476 has4 and 5, No. 42154 has 5 and 6, No. 63421 has4and4, No. 63423 

 has 5 and 5, No. 49203 has 6 and 6; four skinks have the praefrontals 

 broadly in contact; four have them barely in contact; in two they 

 are well separated; the anterior loreal is usually in contact with the 

 first, second, and third labials though in a few specimens it is separated 

 from the first, still more rarely from the third. 



I have examined three other lizards in the National Collection 

 which possess only three keels to their scales ; these are : 



1 (U.S.N. M. 20810) Leopoldville, B. C. 



1 (U.S.N.M. 62125) Fernandez Vaz, French Congo. 



1 (U.S.N.M. 63362) Kindu, B. C. 



In this respect they agree with M. C. Z. 24812 taken on board a 

 steamer near Lulonga, B. C, and referred by Barbour and Loveridge 

 to macuUlahris. It might be remarked that they have not the coloring 

 of raddonii (type locality, "West Africa") as shown by a fine series 

 from Liberia in the Museum of Comparative Zoology, though the 

 white lateral line is present in the Kindu and Lulonga specimens. 

 It is idle for me to speculate as to their status until larger series of 

 West African and Congolese raddonii and macuUlahris are available 

 for study.

 remaining six specimens have been compared with those from Kagiado
