74 Mr. G. A. Boulenger on a 



purpureusy 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 Meyerinhiiy Steind., is, I suggest, only a variety of 



S. octolineatuSj Schn. 



3. Chalcides Simonyi, Steind., from Fuertaventura, I regard 



as a variety of C. viridanus^ and as there is a C. viri- 

 danusy var. Simonyij either of the names will have 

 to be changed. My reason for not accepting C. Si- 

 monyi 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. histriata^ /5, and with 36 

 scales round the middle of the body, agrees precisely 

 in its proportions with C. Simonyij as may be seen 

 from the following measurements : — 



milliin. 



From suout to vent 87 



From snout to fore limb 2o 



Head (to ear-opening) 13 



Width of head 10 



Fore limb 15 



Hind limb 22 



Tail (reproduced) 78 



4. Molge Luschani^ Steind. — I have no doubt this is a Sala- 



mandra. There seems to be less diifercnce between 

 Salamandra Luschani and S. caucasica than between 

 the latter and S. maculosa.

Gongylophis Muelleri. 



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 ; live 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
