310 DR. A. GUNTHER ON REPTILES AND FISHES [June 28, 
CuaMztTortus (g. n. DipsapIDARUM). 
Body and tail of moderate length, rather compressed ; head de- 
pressed, broad behind, and distinct from neck, with the snout rather 
short. Rostral shield of moderate size; nostril between two nasals ; 
loreal united with lower anteocular, entering the orbit ; another ante- 
ocular above. Scales smooth, with a single very small (or without) 
apical groove, those of the vertebral row not enlarged ; subcaudals 
two-rowed. Posterior maxillary tooth longest, grooved. 
CHAM@ToRTUS AuLicus. (PI. XXVI. fig. 2.) 
Shields on the upper side of the head normal; the vertical is 
elongate, twice as long as broad, much longer than the frontals 
together, and nearly as long as the occipital ; the latter is rounded 
behind. The shield which represents the united loreal and lower 
anteocular is subtriangular, as high as long; the upper anteocular 
reaches just to the upper surface of the head. Eye of moderate 
size, with vertical pupil. Temporals 1+2+3, the anterior in con- 
tact with the postoculars, which are two in number. Eight upper 
labials, the third, fourth, and fifth entering the orbit. Ten lower 
labials, the five anterior of which are in contact with the front chin- 
shields. Two pairs of oblong chin-shields, the anterior bemg a little 
longer than the posterior. Ventrals 189, obtusely keeled on the 
sides ; anal entire; subcaudals 86. 
The head has a whitish ground-colour, but it is densely and sym- 
metrically spotted with brown; a brown streak commences from the 
nostril, and passes through the eye to the angle of the mouth. Each 
labial and each scale on the temples and nape with a brown spot. 
Upper parts brown, with narrow whitish cross bars, which become 
less distinct on the hind part of the body, very similar to the mark- 
ings in Lycodon aulicus. The white and brown colours are equally, 
though irregularly, distributed on the sides. Lower parts uniform 
white. 
Total length 13 inches, the head measuring 5 lines, and the tail 
3 inches. 
DENDRASPIS POLYLEPIS. 
Scales in 23 series; temporals 243, both anterior temporals in 
contact with the postoculars, the lower situated above the sixth and 
seventh upper labials. Ventrals 258 ; subcaudals 120. Dull greenish 
olive, hind part of the body and tail with small irregular blackish 
spots ; inside of the mouth black. 
The single specimen in the collection is 6 feet long. 
FroGs. 
Hyprero.uivus FLAvomacutatus. (Pl. XXVII. fig. 1.) 
Tympanum scarcely conspicuous ; tongue deeply notched behind ; 
snout short, broad; upper parts quite smooth, dark violet, with 
rounded yellow spots irregularly disposed ; one of these spots on
