(8) ix. 1897, p. 14. Two perfectly typical young specimens (V. 227-230 ; C. 72, 70) were obtained on the Benito Biver by Mr. Bates. The only difference, apart from tbe markings, between this species and B. stormsi Dollo resides in the number of scales (23 instead of 21), and it is quite possible the two may have to be united when we become acquainted with a larger number of specimens. Hab. Gaboon to Congo. 72. ELAPECHIS GUENTHERI Bocage. Hab. Gaboon to Angola ; Nyassaland. 73. NAIA MELANOLEUCA Hallow. Hab.

It has two praeoculars on one side and one on the other; third and fourth upper labials entering the eye. Scales in 15 rows on the neck as well as on the body ; ventrals 199 ; subcaudals 92. Uniform black above. I am now convinced that N guentheri and N. goldii cannot be maintained as distinct species. 75. DENDRASPIS JAMESONI Traill. Hab. Niger to Angola ; Central Africa. 76.
