striated only in one of the specimens, as they are stated to be in 

 L. cyanogaster, in all the others they are quite smooth as in 

 L. bibronii. Thus, the differences between these species are very 

 unimportant, and finding Koslowsky consider them as synonyms I cannot 

 see but he has good reason to do so. In the young there are on each 

 side two very distinct lateral bands with copper gloss, a broad one 

 from above the eye to somewhat out on the tail, and another more 

 narrow from beneath the eye above the tympanum to the groin. Anal 

 pores 3 — 4. Length of the specimens: 49 -|- 66 mm (the tail a little 

 mutilatedj, 52 -j- 58 mm, 50 -j- 62 mm, 34 -|- 36 mm (the tail mutilated), 

 29 -j- 51 mm, 34 -|- 24 mm (the tail mutilated). 



Mabuia comorensis Peters.

One speeimen from Mombassa, British East-Africa: Captain 

 F. Seyd. Body and heacl 90mm; the tail mutilated. It differs from 

 Peters' and Boulenger's descriptions only somewhat in colour ; the. 

 two rows of dark spots we find in Peters' tigure are wanting and also 

 the lateral band. Back and sides are olive-brown without any sharp 

 border and merging in the light colour of the lower surface. There is 

 however no doubt that it is a Mabuia comorensis Peters, the 

 occurence of which on the African continent thus is stated. In Catalogue 

 of Lizards Boulenger marks with ? Mozambique as locality for this 

 lizard, but living at Mombassa it probably exists also at other places 

 of the East- African coast.

6 specimens, Bibundi, Cameroons (J. Weiler and 0. Rau). 



A very large speeimen, 310 mm in total length, is distinguished 

 from the others in having on the scales of the back several fainter keels 

 beside the three ordinary strong ones. The 4 th upper labial is divided 

 into two, causing that the number of labials before the supraoeular 

 becomes tive, and in colour it also differs in the want of the dark 

 broad lateral band and the narrow light stripe below it. All the upper 

 parts are uniform dark brown without limit merging into the light 

 under surfaces.
