spot, and are obviously the same species. All the specimens agree 

 in having 10 longitudinal ventral scale-rows, 17-19 longitudinal 

 dorsal scale-rows, and 34 transverse dorsal scale-rows. 



The colour and scale-character key given by Schmidt* breaks 

 down for the specimens (d) to {(/), which, according to the key^ 

 would fall under G errhosauriis grandis (Blgr.) of Zululand. 



Both the Lumbo specimens were taken from holes in termite 

 heaps ; m one instance two nnuigoose (Ilerpestes ivori) were 

 occupying the same burrow", all three creatures being found 

 huddled together at the end of the hole. Neai^ly all the Moro- 

 goro specimens were taken among the rocks bordering the river 

 at the south side of the town. The Dodoma specimen was taken 

 on a rocky kopje in desert countiy. 



The examination of the stomach of one of the Lumbo specimens 

 revealed small beans and grass with a single leg from a beetle. 

 As already mentioned, one captive specimen seized and ate a 

 lizard {Eremias spekii). From one of the Lumbo specimens five 

 tapeworms wei'e removed, each about a foot long.

Specimens possibly belonging to this sj)ecies, and certainly- 

 referable to it according to the key and descriptions in the 

 ' Catalogue of Lizards,' have been placed under G. Jiavigularis 

 (Gray) for reasons stated below. 



Gerrhosaurus flavigularis (Gray). 

 Blgr. Cat. Liz. iii. 1887, p. 122. 



A large series of Gerrhosaurus of this group were collected at 

 Nairobi, Moschi, Morogoro, Mkuyuni, Dai--es-Salaai«, and Lumbo. 

 Also seen at Gonya, Handeni, and Kerogwe. 



In his admirable paper on the " Herpetology of the Belgian 

 Congo," Schmidt t suggests that all South and East African 

 species of this group should be known aajlavigidarisjlavigidaris ; 

 whilst he proposes to retain the name of nigrolineatus for the 

 West Afrioaii forms which have a preponderance of nigrolineatus 

 characters, these to be known as jiavigularis nigrolineatus. The 

 key which he applies for the distinguishing of the two races is 

 as follows : — 



CC. Tj-mpaiiic shield narrow ; a dorso-lateral stripe ; dorsals in 



54-64 transverse rows Jlaviffidaris. 



D. Dorsal scales in a transverse row 20-26, mode 22 (South and 



East Africa) snhs-p. flavigularis.
