74 Mr. G. A. Boulenger on a 
purpureus, Cant., to be the same as L. effrenis; the 
latter has three labials in contact with the eye, the 
former only two. The type of Lycodon ophiteoides, 
Blkr., is preserved in the British Museum. 
2. Simotes Meyerinkii, Steind., is, I suggest, only a variety of 
S. octolineatus, Schn. 
3. Chalcides Simony?, Steind., from Fuertaventura, I regard 
as a variety of C. viridanus, and as there is a C. viri- 
danus, var. Stmony?, either of the names will have 
to be changed. My reason for not accepting CO. Si- 
monyt as a valid species, although some of its 
characters do not fit into the diagnosis I have given 
of C. viridanus (Cat. Liz. iii. p. 402) is that a 
female specimen from Grand Canary, preserved in 
the British Museum, falling, as regards coloration, 
into Steindachner’s var. bistvtata, 8, and with 36 
scales round the middle of the body, agrees precisely 
in its proportions with C. Sdmony?, as may be seen 
from the following measurements :—

4, Molge Luschani, Stemd.—I have no doubt this is a Sala- 
mandra. ‘There seems to be less difference between 
Salamandra Luschani and WS. caucasica than between 
the latter and S. maculosa.

Gongylophis Muellert. 
Rostral large and broad, with angular horizontal edge ; 
upper surface of snout and crown with small smooth shields, 
the largest of which is an azygous shield behind and wedged 
in between the internasals, which form a short suture behind 
the rostral; five shields from eye to eye across the forehead ; 
nine or ten scales round the eye, which is separated from the 
labials by a single series of scales ; nine upper labials. Scales
