indicated in the type. The ventrals and subcaiidals of this paratype 

 are also freely sprinkled with black. 



Remarlis. — On general principles I should have preferred to ex- 

 pand the description of aethiopissa to include the present form were 

 it not for the fact that all 6 East African specimens agree in possessing 

 15 scale rows and 7 labials, while West African snakes recorded since 

 1862 invariably have from 17 to 19 scale rows and 8 labial shields. 



Measurements. — Length of head to end of parietals, 20 mm.; 

 length of head and bod}^, 760 mm.; length of tail, 387 mm.

1 (U.S.N. M. 41694) Juja Farm, K. C. (Sm. Afr. Exped.) 1909. 



This is a juvenile example and very dry, in consequence of which 

 the identification is a little doubtful. Mid-body scale rows, 21; 

 ventrals, 184; anal divided; subcaudals, 80; labials, 8, of which the 

 fourth and fifth enter the orbit. Total length, 300 (233 + 67) mm.

Coronella scheffleri Sternfeld, 1908, Sitzber. Ges. Naturf. Freunde, Berlin, 

 p. 93; and 1908, Mitt. Zool. Mus. Berlin, p. 243, figs. 1 and 2. (Type 

 locality Kibwezi, K. C.) 



1 (U.S.N. M. 40931) Ulukenya Hills, K. C. (Sm. Afr. Exped.) 1909. 



Mid-body scale rows, 21; ventrals, 201; anal divided; subcaudals, 

 91, paired except the first 2, which are single; labials, 8, of which the 

 fourth and fifth enter the orbit. 



This snake is intermediate between C. semiornata and C. scheffleri. 

 It agrees with semiornata rather than scheffleri in the key character 

 of its rostral which is a good deal broader than deep instead of only 

 slightly.^ Actually the depth is about 1.75 mm. and the length 

 2.5 mm. Nor does the snout project more than in a specimen of 

 semiornata from Dar es Salaam or others from Kipetu, T. T. It also
