more clumsy than in the two preceding species. Above 
varied with brown of two shades ; below deep yellow, 
marked with black square spots ; scales bordered with 
black, or with white. E. of scales, 17. S. 160 + 50. 
6. CoRONELLA Baliodeira, the only species of the genus 
Coronella known in Malayan Asia, was discovered in Java 
and Sumatra. Of a size less robust than most of the 
other species, it approaches in its form the Calamars ; but 
its eyes are very large, and its head high. Above of a 
vivid brown, relieved by white ocellated spots ; below 
yellowish. S. 128-f-08. E. of scales, 13. 
Europe only produces a single species, 
7. Coronella L^vis, which prefers dry situations to 
low and swampy places ; it is of a very shining brown 
bay, ornamented with chequered, irregular patches of 
black, which form a very characteristic pattern on the 
head : below it is yellowish, marked with square black 
spots. S. 175 + 55 ; E. of scales, 21. The young of this 
species are hatched in the belly of their mother. The 
southern countries of Europe produce a climatal variety, 
distinguished by its more vivid tints. 
8. Coronella Chilensis (the Tachymenes of Wieg- 
mann) resembles that of Europe, but its head is more co- 
nical, and is covered by smaller plates ; its tail is shorter, 
and the upper parts present four deep-coloured rays, ex- 
tending from the occiput, whilst we find below several rows 
of blackish marks, often well defined. S. 158 -f 46. E. S.

The four following species are found at the Cape, and 
differ from the preceding species in several respects. 
9. Coronella rhombeata recalls, by its general organi- 
zation, the European species, although it approaches by 
its elongated form, the Psammophis. Its head is small, 
conical, and terminated by a straight rostral, which is pro- 
longed on the top of the muzzle ; the other plates of this 
part are narrow, and the occipitals short. A grooved pos- 
terior tooth is observed in the jaws. The yellowish-brown 
of the upper parts is ornamented with three or four rows 
of ocellated spots of a lozenge form. S. 155 + 72. E. S. 
17.
