EAST AFRICAN SNAKES. 887 



28 inches of the sand snake whose hodji measured 33| inches; 

 unfortunately, in the excitement of killing the cobra the greater 

 parb of tlie tail of the sand snake had been cut off, but other 

 specimens of this body length had tails of between 12 and 

 13 inches, so that a 50J-inch snake was engaged in swallowing a 

 4G inch snake and would doubtless have succeeded. 



From one of these Lunibo snakes I removed three worms 

 {Poh/deljjhis quadricornis Wedl.) which measured 14 mm. X 6 mm. 

 A Morogoro specimen, which was ailing and would not feed, 

 spued up a (piantity of watery and slimy matter on the morning 

 of 9. iv. 18 and died the same evening. There were no visible 

 pai-asites in the stomach, but one lobe of the liver appeared to be 

 full of cysts. 



When crossing the Wembere Flats (9. xi. 21) I came upon a 

 sand snake at 8 a.m. that was apparently dying of thirst. It 

 offered no resistance to being picked up and died shortly afterwards. 

 The stoiAiach wns clean and empty. It had dusky ventral stripes 

 like the brighter ones of P. subtccniains. 



PsAMMoruis BisBuiATUS Petcrs. 



Blgr. Cat. Snakes, iii. 1896, p. 168. 



Three specimens from Kahe, Ikikuyu, and Dodoma. This 

 species seems partial to sa.ndy or rock-strewn desei't country. 

 The Dodoma snake, though only measuring 12|- inches, had a 

 skink {Lygosoma ferrandii) in its stomach, as hnd also the 

 Ikikuyu specimen. 



PSAMMOPIIIS ANGOLENSIS Bocage. 



Blgr. Gat. Snakes, iii. 1896, p. 170. 



Six specimens from Kilosa and Izikisia, and two which were 

 without locality in a bottle at Morogoro, at which place they were 

 probably taken. Three were taken on paths and one twisted into 

 the grass of a. banda five feet fi'om the ground. This last had 

 nine upper labials on the left lip, the right having the normal 

 number of eight. 



TUELOXORNIS KIRTLANUII Hallow. 



Blgr. Cat. Snakes, iii. 1896, p. 185. 



One specimen from Zengeragusu, also seen at Lumbo. 



The largest Morogoro specimen measured 58| inches (919 -f 

 548); the Zengeragusu female is 53| (933 + 415). 



The Morogoro specimen laid 8 eggs on 16.1.18. These 

 measured 27 X 15 mm. The yellowish parchment-like shells were 

 irregular in outline with many concavities. 'J'hey were laid 

 singly at intervals of five to ten minutes. The Zengeragusu snake 

 laid two eggs on 24. xii. 21 which were dry Avhen found, they 

 then measured 38x15 and 34x14 mm. respectively. As the
