of moderate length. Eye of moderate size ; two pairs of fron-

Rostral shield broader than deep, just reaching the upper 

 surface of the head ; anterior frontals small, scarcely half as 

 large as posterior ; (nostril very narrow, between two small 

 shields*). Loreal region covered by two or three scales, one 

 of which points upwards and reaches the vertical ; prgeorbital 

 larger than the seven other scales which complete the orbital 

 ring ; occiput and temple covered by equally small scales, the 

 occipital being represented by a small shield situated behind 

 the superciliary shield ; nine or ten small upper labials. Scales 

 much imbricate, with the keel rather flat. Ventrals 192 j 

 anal entire ; subcaudals 51. 



Upper parts yellowish olive, with two dorsal series of 

 blackish spots, the spots of several pairs confluent into cross 

 bands ; flanks with smaller and less distinct spots ; lower parts 

 uniform white. 



I have examined one specimen of this singular snake. It 

 was found by Mr. John Chapman on the Zambezi. The spe- 

 cimen is 24^ inches long, the head being 10 lines, and the tail 

 3^ inches long. 



Lycodon rufozonatus (Cant.). 



In two young examples from Formosa the loreal does not 

 quite extend to the eye, although it is produced backwards. 



O'pTiites alboficscus (D. & B.). 

 Occurs also in Formosa ; feeds on lizards. 

 Boodon lineatus (D. & B.). 

 Specimens from the Zambezi and Zanzibar have the scales 

 in twenty-five or twenty-seven rows. Its food consists of 

 nocturnal lizards, as well as mammals. 



Lycophidium irroratum (Leach).

 Metoporhinn irrorata, Gthr. 

 Alopecion fasciatinn, Gthr. 



* This portion of the head h unfortunately so much dried tliat the 

 nostrils have become rather indistinct j they must be extremely small.
