Causus licutensxeini Jan. 



Blgr. Cat. Snakes, iii. 1896, p. 470. 



This specimen was one of nine collected on the Yala River by 

 Mr. li. J. Allen Turner and is now in the Nairobi Museum. 

 Typical specimens are olive-green in life and plumbeous or lead- 

 colour when preserved ; the specimen under consideration agrees 

 in every way with the published description of C lichienstemi, 

 except in the unusual niarkings and number of ventrals ; but 

 typical specimens fiom the same locality have also the same 

 number. 



Head and body 200 mm.; tail 15 mm.; costals 15; ventrals 

 158 ; caudals 17 ; labials 6. 



General colour grey (brilliant leaf-green in life like ChloropMs^ 

 but with a velvety tone — Turner). Head black. White line 

 commencing at the first scale behind the last labial following the 

 outline of the head passing along the edge of the supraoculars just 

 above the eyes, and finishing on the corresponding scale on the 

 other side. LoAver portion of all the upper labials and whole of the 

 3rd china-white. An inverted V on nape, apex just reaching to 

 posterior border of parietids. Throat pure white with a black U 

 corresponding to outline of throat and reaching to oral margin on 

 the second labial only. Third and fourth gular scales (or ventrals) 

 black, 5th and 6th white, 7th, 8th, and 9th black, 10th and lltli 

 white, remaining ventrals grey with faint white transverse bars 

 on every 13th or 14th scale. Black V-shaped markings along- 

 whole of dorsal surface at intervals of seven to nine scales ; nine 

 veiy distinct white lateral marks corresponding to bars on the 

 belly, the 10th just above vent forms a complete white ring three 

 scales wide, white spot near tip of tail, white freckles on anterior 

 part of black. 



Another specimen ]\Ir. Turner tells me was quite black in lif^, 

 similar to its preserved colour : a brown stripe from the posterior 

 border of the eye passes along the whole outer row of body scales ; 

 the only other marking is a transverse brown band four scales 

 wide across the back above the vent. Its formula is iis follows : — 

 267 mm. ; 26 mm. ; 15 . 144 . 20 . 6.
