like marking on the head of B. nasicornis is completely absent. ‘‘At Memmeh 
Town another specimen was found which contained a number of lingatulids in 
the wind-pipe and lung-sac. The local name of this snake is Kissadi.”

“These snakes remain perfectly still in low vines or bushes and allow one to 
approach quite close. One was seen coiled up in a bush about four feet from the 
ground. I struck it a powerful blow with a stick thinking to break its back, but 
for several minutes could not again find it, though the ground was open and 
nearly bare. At length it dawned on my sight posed in stiff and motionless 
attitude among a few spears of grass which it exactly matched in color. It had 
lately swallowed a multimammate mouse. 
Another I nearly brushed against while searching for a bird I had shot in a 
thicket. The snake stayed motionless in a green vine about five feet from the 
ground until a native shot it through with a palm-rib arrow. On another oc- 
casion Coolidge killed one coiled up on the ground at the foot of a forest tree; 
in its stomach was a Crocidura.”

from Firestone Plantation, Du River, Liberia, collected by G. M. Allen, July, 1926. 
Apparently related to L. conraui Tornier from Cameroons, with which it agrees in having trans- 
versely enlarged subcaudals; This immediately distinguishes it from L. fischeri Boulenger, from 
Sierra Leone. Diagnostic characters are: snout twice the orbital diameter; nostril between five 
scales or plates; large size of mental; enlarged subcaudals. 
Description. — Head oviform, much longer than broad; snout twice the diameter of the eye, 
longer than the distance between the eye and the ear-opening; ear-opening very small, roundish. 
Rostral broad; nostril pierced above and behind the suture of the rostral and first labial, between 
rostral, first labial, two small scales and an enlarged supranasal; two scales between enlarged supra- 
nasals; seven upper labials; six lower labials; mental large, subtriangular not extending beyond the
