UEPTILES FROM TRANSVAAL. 229 



specimen, the diameter of the body 76 times iu the total length, 

 length of tail 19 times. Our specimen measures 190 mm. 



10. Pseudaspis cana L. 

 One young specimen, 



11. Philothamnus semivariegatus Smith. 

 One specimen. 



*12. Prosymna Sundevallii Smith. 



One specimen, with two internasals separated from each 

 other, a single praefrontal in contact with the rostral, one 

 prae- and two post-oculars and seven upperlabials , the third 

 and fourth entering the eye. Temporals 2 -[- 2 , ventrals 

 152, subcaudals in 26 pairs. Upper part of the head red- 

 dish brown with a yellow spot on a part of the frontal 

 and of the parietals. Back and sides reddish brown with 

 a yellow line along the middle of the back ; this line , 

 somewhat broader than one scale , is everywhere interrupted 

 by small brown spots. Underpart whitish, with irregular 

 darker spots, a reddish line running over the middle of the tail. 



13. Dasypeltis scabra L. 



Two specimens , with a dorsal series of large squarish or 

 rhomboidal dark spots, separated by light intervals, alter- 

 nating with a lateral series of dark spots or crossbars. On 

 some places there is continuity between the dorsal and the 

 lateral spot, so indicating A -shaped dark markings. 



14. Psammophis sibilans L. 

 One specimen. 



15. Dryiophis Kirtlandi Hall. 



One specimen , resembling in coloration Günther's figure 

 of D. Oatesii '), but differing from Günther's description in 

 having the rostral reverted to the upper surface of the 

 head, and in having three postoculars ^). Another specimen 

 in our Museum, collected in the neighbourhood of the 



1) Matabeleland and the Victoria falls. Appendix III, Herpetology , p. 330. 

 London, 1882. 



2) After comparing Günther's figure with our Transvaal specimen, I should 

 feel inclined to think that G's Dryiophis Oatesii also has three postoculars on 

 its left side.
