428 Dr. A. Giluther on new Species of Snakes. 



The number of ventral shields varies much in examples 

 which I refer to L. Horstockii. I find 



208 in one example from West Africa. 



208 in one, habit. ? 



202-200 in two, variety with square white dorsal spots. 

 188 in one from the Cape. 

 176 in one from Angola. 

 153 in one from Ambrizette. 



Cylindrophis. 



The snakes of this genus are viviparous. 



Hydrophis Japemoides (Gray). 

 An example, 3 feet long, from Madras, has only one post- 

 ocular. 



Callophis japonicus. PI. XVII. fig. C. 



Ground-colour whitish in spirits, with a reddish tinge. An- 

 terior half and sides of the head black ; a black band, one 

 scale broad, rmis from the occipital, along the vertical line, 

 nearly to the tip of the tail ; another, narrower and less distinct 

 line runs along the meeting edges of the third and fourth 

 outer series of scales. Body with black cross bands besides, 

 the width of which is about one-third of the interspace be- 

 tween them : some extend round the belly, others do not ; 

 there are thirteen of them on the tmnk and tAvo on the tail. 

 Belly with a series of large round black blotches, each blotch 

 corresponding to the middle of the interspace between two 

 black dorsal bands. 



Seven upper labials ; two postoculars ; ventrals 205 ; anal 

 entire; subcaudals 31. 



One specimen, 9 5 inches long, was obtained by Mr.Whitely 

 at Nagasaki. 



Elaps Batesii. PI. XVII. fig. D. 



Upper labials seven, none of them in contact with the occi- 

 pital ; one prse-, two postoculars; temporals 1-1-1-1-5; ven- 

 trals 196 ; anal bifid ; subcaudals 50. Upper parts uniform 

 shining black ; trunk with about sixty transverse series of 

 very small yellow specks ; each supraorbital provided with a 

 fiimilar spot; lower parts of the trunk white (in spirits), with 

 a few. irregular yellow cross bands ; lower part of the tail with 

 alternate yellow and blackish bands. 



• One example, 12 inches long, was sent by Mr. Hauxwell, 

 a correspondent of Mr. Bates, from Pebas.
