There are three specimens from Mus. Drottningh., named 
Coluber nebulatus. One of these only, however, proves to be 
identical with Petalognathus nebulatus (L.) Dum. & BIBR., and 
it is this specimen that LINNEAUs used as type for his de- 
scription and figure. The two others are specimens of Lyco- 
gnathus cervinus (LAUR.) Bou.

Coluber Saturninus.

LINN2US pronounced this specimen to be a distinct Spe- 
cies and some post-Linnéan authors have maintained that it 
was so. GÖUNTHER and BouULENGER, however, put it in their 
catalogues as synonymous with Coluber (Herpetodryas) fuscus 
L. I am able to prove the correctness of this. 
LiNN2a05's Coluber fuscus is an old and dark specimen, 
his Coluber Saturninus is a young and light one of the 
same species. The light black-edged erossbands, which, accord- 
ing to BouLEnGEr, ought to be found on the form saturninus, 
are not visible, as the specimen is very much discoloured. 
AA light streak along the back and small brown spots scat- 
tered about appear on the pale grey ground-colour. 
Coluber atrox.!
