428 Dr. A. Giinther on new Species of Snakes. 
The number of ventral shields varies much in examples 
which I refer to L. Horstockii. 1 find 
208 in one example trom 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 lapemoides (Gray). 
An example, 3 feet long, from Madras, has only one post- 
ocular. 
Callophis japonicus. Pl. 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, runs 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 trunk and two 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, 94 inches long, was obtained by Mr. Whitely 
at Nagasaki.

Upper labials seven, none of them in contact with the occi- 
pital; one pre-, two postoculars; temporals 1+1+42; 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 
similar 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. Z e Srrbaae
