ON THE PHYSIOGNOMY OF SEEPENTS. 
relieved by three or five ranges of spots, of which the 
middle ones are very large, and more or less orbicular. 
A bifurcated black mark on the occiput, and a band be- 
tween the eyes. Below deep yellow, with square, alter- 
nate, black markings. 
Coluber leopardinus. — System of colouring analogous 
to that of Coluber guttatus, with this exception, that the 
spots on the back are smaller, and often confluent. Shape 
more delicate than the preceding ; head as in the Coluber 
JUsculapii; twenty-three rows of smooth scales. S. 240 + 75. 
Inhabits the south-east of Europe, and northern Africa. 
27. Coluber conspillatus. — Very analogous to the 
last, in the system of its colours, but with a more heavy 
shape ; it has larger scales, and several little frenal plates ; 
transverse bands instead of spots on the trunk; a club- 
shaped spot, preceded by an angular mark, on the occiput ; 
twenty-one rows of scales. S. 210 + 68. Native of 
Japan. 
The limits of the genus Coluber, so rich in species, 
will some day be, no doubt, considerably extended, when 
we can arrive at a more accurate knowledge of the nu- 
merous species superficially indicated by travellers. I 
shall only quote the following : — (1.) Coluber atro- 
Fuscus of Daudin, vi. p. 285, rests on the authority 
of the delineation of the head and posterior of the body 
of a snake, mentioned by Bussel. (2.) Coluber ob- 
scuRus of Daudin, vi. p. 363, established after Russel, 
i. pi. 18. (3.) Coluber Plinii of Merrem, Tent^ p. 
101 ; the Coluber pictus of Daudin, vi.| 347, — names 
which have for their type Russel’s pi. 29, vol. i. : this 
species is probably identical with the Coluber Triscalis 
of LiNNiEUS, from which the Coluber corallinus of the 
same author, figured in Seha^ ii. pi. 17, § 1, appears not to 
differ ; a good figure of Coluber Triscalis is found in 
Seha^ ii. 38, 3. — Schlegel, part ii.
