130 DR. A. GUNTHER ON REPTILES AND [Feb. 20, 
ascending on the sides. Specimens from Ceram and Amboyna show 
generally a light colour. 
To this species I refer now the following Snakes, described by 
various authors :— 
1837. Lycodon modestus, Schleg. Essai ii. p. 119 ; from Amboyna. 
1854. Lycodon modestum and L. lividum, Dum. & Bibr. pp. 380 
and 381; from Amboyna and Pulo Samao. 
1861, Adblabes greineri, Bleeker, Rept. of Amboyna; from Am- 
boyna. 
1861. Coronella rosenbergii, Bleeker, Rept. of Ceram; from 
Ceram. 
1863. Lielaphis holochrous, Giinther, P. Z. S. p. 59; from 
Ceram. 
1874. Lycodon aruensis, Doria, Ann. Mus. Gen. p. 352; from 
the Aru Islands. 
The specimens which I have examined are from Ceram, Mysol, 
and Amboyna ; and they differ less among each other than the two 
specimens from the Duke-of-York Island. Both have a syncrante- 
rian dentition (ten teeth); but one has eight upper labials, all the 
subcaudals divided, and 197 ventrals; the other has seven upper 
labials, 180 ventrals, and, singularly enough, only the first two and 
the last nineteen subcaudals divided, the sixty-three middle ones 
being entire. 
Other species belong to the same genus, and one or the other may 
eventually prove to be identical with the one described, viz. :— 
Lielaphis batjanensis, Gthr., from Batjan. 
Zamenophis australis, Gthr., from Cape York, with which Lycodon 
keyensis of Doria, from the Key Islands, appears to be identical. 
Lycodon parvus, Meyer, from Jobi. 
TROPIDONOTUS HYPOMELAS, sp. n. 
Body very slender; head moderately long and deep; eye large ;
