Blgr. Oat. Snakes, ii. 1894, p. 99. 



Twelve specimens from Dar es Salaam, Ilonga, Kimamba, 

 Kilosa, Kabare, and Lumbo. 



None of tliese exceeded in size a female from Morogoro, 

 measuring 51 1 inches (8374-466), taken 25.xi. 17^, One speci- 

 men had only 149 veutials and two had 159 sub-caudivls. 



The coloration of Lumbo specimens was strikingly different 

 from the grass-gioen examples, of which a long series were taken 

 previously. In Lumbo specimens the head and neck were pale 

 green ; body mauve ; both freely speckled with black. The tail 

 was plumbeous; throat china-white; belly and sub-caudals 

 wliitish with a mauve tint. Ventral keels of a mauve colour. 

 The tongue at tip and base was black, but the middle portion 

 blight Cambridge-blue. All four specimens taken at Lumbo 

 were the same. 



Attracted by the outcry raised by birds, I captured the Frere 

 Town specimen whilst it was descending the almost vertical tree- 

 trunk, taking advantage of eveiy irregularity in the bark. 



A Spotted Wood Snake wns found swallowing a gecko {Ilemi- 

 dactylus viabouia) in the fowl-house and only the tail was to be seen. 

 Immediately it was approached the snake disgorged the gecko, 

 and on being seized by the tail ivfiated the neck and anterior 

 portion of the body vertically, and struck at my hand repeatedly. 

 Here then is another tree-snake with the same habit of inflation 

 when alarmed or annoyed as the Boomslang and Bird Snake. 



Another specimen on being caught in a thatch disgorged a 

 gecko of the same species, and a third snake had swallowed a 

 young toad (Bvfo regularis). 



During a flood one specimen was found on a maize stalk, 

 five feet above the water. A young one was recovered from 

 the stomach of a One- streaked Hawk (^Kavpifalco nionogrammica).

A specimen sent me from Bukoba extends the range of this 

 scarce reptile westwards; it was described fiom British East 

 Africa. I have also had the pleasure of examining three more 

 specimens collected by Mr. J. A. Turner in the Yala lliver region 

 near Mt. Elgon.

 It measured 7 feet 5| inches (1671 -f 584), and eight specimens
