6 specimens from Kibonoto, one caught in May, one 21 /7, one 30 7, one 8 /8, one 

 and one without date. In five of these there are only 3 scales between the upper 

 posterior temporal, and behind the parietals; in one of them one of these scales, or 

 small plates, is, however, semidivided. In the fifth specimen the upper posterior tem- 

 poral is separated from its fellow of the other side by 5 small scales. 



A seventh specimen had no label indicating where it had been collected but was, 

 no doubt, also from Kibonoto.

A specimen of Dendraspis from Kibonoto differs from all the others in several 

 respects and at the same time from the descriptions of hitherto known forms as well. 

 The most striking difference is the length and the narrowness of the frontal, the 

 arrangement of the temporals etc. 



Rostral broader than deep. Internasals short, their length contained about 

 1 3 /4 times in the length of the praefrontals. Frontal long and comparatively narrow, 

 its width being contained 1 Va in its length, it is nevertheless shorter than its distance 

 from the end of the snout, and than the parietals. Two preeoculars, the upper not 

 in contact with the frontal; a subocular wedged in between lower prseocular and third 

 and fourth labials. Three or four postoculars (the lower of which may be termed 

 subocular). Two anterior temporals, behind the upper of these a second upper tem- 

 poral largely in contact with the parietal ; this second upper temporal is very large 

 so that it is separated from its fellow only by a single occipital shield, and from the 

 labials by a single posterior lower temporal (temporals thus 2 + 2). 8 upper labials 

 on one, 9 on the other side, fourth entering the eye, second and third much deeper 

 than first and in contact with praefrontal. Three lower labials in contact with anterior 

 chin-shields which are about as long as the posterior. Scales in 19 rows, outer not 

 shorter than dorsals. Ventrals 227, an divided, subcaudals 102. 



The colour appears to be uniformly green. 



It is of course difficult to say if this single specimen represents a different spe- 

 cies or only a remarkable individual aberration of D. angusticepx, but as the distinct- 

 ness is so clear I have preferred to name it.

6 specimens from Kibonoto, one caught the "/?, the others in August 1905. 

 In one ot the specimens the angle formed by the upper end of the rostral is less 

 than a right angle.
