differs from scheffleri and agrees with semiornata in its internasals, 

 which are as long as broad, not longer; the frontal is exactly as figured 

 and not as stated in the text, "once and two-third times as long as 

 broad"; it is much longer than its distance from the end of the 

 snout, not "as long as its distance from the rostral"; it is shorter 

 than the parietals, not equal to them. The number of its subcaudals 

 are exactly the same as in the type of scheffleri and its ventrals only 

 three more. Without topotypic material for comparison this iden- 

 tification must remain extremely doubtful. 



It appears superficially much more slender than semiornata, but 

 actually the mid-body diameter is included in the length 41 times in 

 both the Ulukenya and Dar es Salaam snakes and the tail is included 

 3 and 3.2 times in the body length, respectively. The absence of 

 hypophyses to its vertebrae preclude the idea of its being referable 

 to the genus Coluber {Zamenis Authors), which has a representative 

 farther to the north. 



CORONELLA CORONATA (Schlegel)

1 (U.S.N.M. 42230) Rhino Camp, L. E. (Sm. Afr. Exped.) 1910. 



Mid-body scale rows, 19; ventrals, 179; anal divided; subcaudals 

 77; labials, 8, the fourth and fifth entering the orbit; 4 lower labials 

 in contact with the anterior chin shields. Total length, 540 (420 + 

 120) mm. 



This snake agrees perfectly in characters and color with a specimen 

 of C. coronata from Sakbayeme, Cameroons (M. C. Z. 22831) as also 

 with one from Niangara, Belgian Congo, referred to by Schmidt, 

 with which author I agree in considering it probable that C. regularis 

 (Fischer) should be united with C. coronata, for the Rhino Camp 

 snake also agrees in coloring with C. regularis.

Mid-body scale rows, 15; ventrals, 143; anal divided; subcaudals, 

 110; labials 8 on left side, with the fourth entering the orbit, 9 on right 

 side, with the fifth entering the orbit. Except for the extra labial on 

 the right side and that the length of the lower anterior temporal equals 

 its distance from the posterior nasal, this specimen agrees in every
