(jcrrliosaimis Havi^ularis WIEGMANN. 

 (PL 1 Fig. 1 a & b) forma intermedia. 



A fine specimen, nearly 400 mm. although the tip of the tail has been broken 

 and partly reproduced, caught on the steppe near the Natron lakes, Kibonoto 6 /9 1905. 



This animal differs as well from G. nigrolinealus as from flavigularis with which 

 it may be related, if these two species are held apart and not united as TORNIER 

 has done lately. 1 



The present specimen has a long suture between the prsefrontals as in G. ni- 

 t/rolineatus, but only 22 series of dorsal scales all of which, even those of the flanks 

 are strongly keeled. The full description is as follows: Head shields smooth. Nasals 

 in contact behind rostral. Frontonasal as broad as long. Praefrontals with a long 

 median suture. Frontal much shorter than fronto-parietal and parietal together. A 

 narrow tympanic shield. Interorbital breadth posteriorly across the third supraoculars 

 contained 2 7a times in the distance between tip of snout and ear-opening. 22 series 

 of scales all strongly keeled and also provided with smaller lateral keels. 52 shields 

 between the chinshields and the large praeanal shield. 14 femoral pores. 



Dark brown above with three yellowish white dark-edged stripes, the median 

 narrowest. Sides minium red with dark bars extending from the back. These are 

 at first 2 scales broad but lower down on the flanks only one scale broad. Across 

 these bars there are short longitudinal yellowish white stripes on each scale. 



The differences from the descriptions of 0. nigrolineatus and G. flavigularis are 

 thus very conspicuous, but as TORNIER (1. c.) has described from Dar-es-salaam full}' 

 intermediate forms between both these supposed species, it appears difficult to main- 

 tain them. The best thing may therefore be to use the oldest name G. flavigularis 

 for all and distinguish the different varieties with a third name until the matter is 

 .still better elucidated by greater collections from different localities.
