The types of the new snakes described above are in the 
British Museum, and formed part of a small collection on 
which Dr. F. Werner has recently reported (Verh. zool.-bot. 
Ges. Wien, xiv. 1895, p. 190). I take this opportunity to 
observe that the lizard described as Gymnodactylus africanus, 
Werner, is a Gonatodes, closely allied to the Indian G. or- 
natus. It should stand as Gonatodes africanus.
