MACROPROTODON CLTCULLATUS. 311 
The spots on the ventrals may be feeble and sparse in some, while in others they are 
even more strongly developed than in the Egyptian specimens. This type of coloration 
occurs also in specimens from the city of Morocco, whereas in a specimen (the type 
of Coronella Icevis, Gthr.) from an island off the coast of Mogador the coloration 
recalls the Egyptian snakes, but the ventrals are immaculate. In a specimen with no 
more detailed indication of its origin than " Morocco," the coloration of the dorsal 
surface is that of the Hammam Meskoutine individual, but the ventrals are covered 
with great black spots, and the entire head, upper and under surfaces to the nape, 
with the exception of a narrow yellowish line along the upper labials, is deep bluish 
black. The extent to which the black hood is developed is very varied, and in some 
it is very feebly developed, while in others, such as in Tangier specimens, it becomes 
broken up into bands, nuchal, transocular, and subocular. In this detail of coloration 
they are exactly resembled by the Andalucian snakes, which in the coloration of their 
bodies alone resemble that of the Tangier examples of the species, which differ but 
little from those of Algeria and Tunisia.
