In the Catalogue of Snakes BouLEnGER only speaks of 
green-coloured specimens of Dryophis xanthozona, which would 
not agree with the supposition that the specimen in question 
belongs to this species. It is, however, probable that the 
colour of this form varies as well as that of the nearly 
related Dryoph. prasinus BoiE, from which it seems to differ 
only in a slightly different number of shields. The colour 
of this latter is, according to BouLENGER, sometimes green, 
sometimes pale-olive or gray-brown. In other respects the 
description of Dryophis xanthozona agrees completely with 
this speeimen. 
Therefore the Linnean name mycterizans ought to be 
given to this snake, which will thus be named Dryophis 
mycterizans (1L.). 
According to the synonymy in BouLENGER'S catalogue the 
Dryophis mycterizans of the authors must instead be called 
Dryoplhis nasutus (L:ACEP.) ScHLEG.

One specimen from Mus. Drottn. 
Total length 480 mm. Cauda 50 mm. Sq. 15. V. 203. &O. 31. 
This specimen differs from the description of Hom. lac- 
teus in BouLENGER's catalogue by two postoculars, the lower of 
which enters the eye only with a corner. The 5:th upper 
labial is not in contact with the parietals, from which it is 
separated by the anterior temporal.
