Mabuia sulcata Peters. 



Bleg., Cat. Liz. III, p. 206. 



5 breeding specimens (3 males, 2 females) from Berseba, German 

 S. W. Africa (coli. C. Berger). 



As I have not seen any note regarding the breeding garb of this- 

 species a Statement about this may be of some interest. 



Breeding males (total lengtlis, 78 -f- 107, 75 -j- 108, 74 -)-...) : chin 

 and throat to fore limbs jet black, tbe black colour extending to the ear r 

 along the sides of the head and above the snout, scattered black dots are 

 also found on the Upper side of the head, on the breast, and on the sides 

 of belly, limbs and tail; the upper surfaces uniform olive brownish (in 

 one specimen the upper side of the tail is almost black) ; the margin of 

 the ear and some dots on the supralabials are red. In one of the specimens 

 this colour is not yet fully developed, the black appearing only as large 

 spots on the throat and the chin. 



Breeding females (total lengtlis, 81 -j- 102, 80 -f- 122 mm) : Chin and 

 throat light red, regularly dotted with black; the red colour extends all 

 over the upper labials backwards to the axil, involving the tympanum, 

 being rather sharply defined from the olive brownish upper parts. Between 

 the red and the brown colours a dark line extends from the snout, along 

 the canthus rostralis, through the eye, above the tympanum, fading behind 

 on the sides of the body. Except throat aud chin the whole under surfaces 

 are light, and unspotted as also the upper surfaces which are olive brown. 



Hylainbates aubryi A. Dum. 



In a collection of Hylambates specimens from Bibundi, Kamerun 

 (coli. J. Weiler and C. Feldmann) I have received several specimens which 

 fully confirm my opinion that Hylambates aubryi A. Dum. and H. rufus: 

 Reichen, cannot be regarded as distinct species (Jahrb. Nass. Ver. Naturk. r 

 Wiesbaden 1909, p. 103). The two figures below are drawn from two- 

 specimens which have been collected at the same place, and which cor- 

 respond in every little detail, except in the development of the web on 

 the hand and foot, I think that Dr. Xieden and other authors which regard 

 the two forms as well distinct species without hesitation would declare 

 the left figure as belonging to a H. rufus and the right to a H. aubryü
