Mr. G. A. IJoulengcr on Snakes from XataL 375 



the j)aiiL't;ils; the pia'IroiitaU have a tendency to divide, a 

 cleft extending along halt" of their length from the posterior 

 angle of the internasal ; loreal square ; two prajoculars, 

 up|>er smaller; two jtostocular.s ; temporals 1+2; seven 

 ujiper labials, third and fourth entering the eye. Scales in 

 lo rows (19 on the neck). Ventrals 208; subcaudals 47. 

 Dark olive- brown, with a yellow vertebral stripe. 



Fhilothainnus semivariegatus^ Smith. 



A female specimen, measuring 940 milliin. ; tail 310. 



This is of interest as the first specimen received t'roin Natal, 

 the original locality whence the species was describci by 

 Andrew Smith. It agrees with the types in the black 

 markings, but differs in the ground-colour being entirely of a 

 bright grass-green above. Temj)oraIs 2 + 2; nine upper 

 labials, fourth, fifth, and sixth entering the eye. Ventrals 178; 

 subcaudals 125. 



Macrelups microlepidotas, Gthr. 



Two fine female specimens^ the larger measuring 1 metro 

 (tail 110 millim.). Tiiis is remarkable in having the rostral 

 nearly twice as broad as deep, its up])er [)ortion measuring 

 one third its distance from the frontal. Both have the post- 

 ocular in contact with the anterior temporal and 25 rows of 

 scales. Ventrals 168, 1(32 ; subcaudals 27, 33. 



Elapechis Sundevalliiy Smith. 



I have now several specimens before me, which differ much 

 in coloration. The adult (up to 880 millim. ; tail o5j are 

 dark brown above, with narrow white cross-bars nearly equi- 

 distant or approximate in pairs, their number varying from 

 48 to 69 ; one specimen has the belly marbled with brown. 

 A young specimen (250 millim.) is alternately barred black 

 and white, the two bars of equal extent, the edges of 

 the white ones of a purer white, which no doubt persist to 

 form the narrow bars of the adult, hi some of the speci- 

 mens the upper part of the rostral measures only two thirds 

 its distance from the frontal. Ventrals 165-184 ; sub- 

 caudals 22-25. 



This snake has recently been recorded from the Upper 

 Zambesi by Feracca (Boll. Mus. Torin. xi. 1896, no. 2b5). 



Naia nigricoUiSy Reinh. 

 I have recently recorded this species from the De Kaap
