manner possible, the better to show itself, and to prevent 
inse6t-eating birds from mistaking it for some other 
palatable form. 
Colony Deer, — Five species of deer appear to be dis- 
tributed in the colony. The common brown savannah 
deer (Cariacus savannarum = C. mexicanus) is so well 
known that it needs no description, the branching antlers, 
with the inner basal snag, sufficiently distinguishing it. 
The large red wood deer or brocket, with the simple 
horns (Coassus rufus), is also well-known, being com- 
monly obtained about the back of the estates, more 
especially on the Essequebo coasts. The " Welbisiri " 
or small wood deer or brocket (Coassus nemorivagus) , 
is common only in the forest trails of the inner parts of 
the country. In spite of its being a very common species 
in the interior, it was only quite recently that I 
was able to secure a suitable specimen for accurate 
identification, and it seems likely that the name "Welbi- 
siri " is given to two distinct species. C. nemorivagus is 
much smaller than the red deer, and is of a very pale 
brownish grey or white colour, with a frontal streak 
before the eyes, and the horns are much finer and 
shorter. The Welbisiri was referred in SCHOMBURGK'S 
" Reisen" to the species C. humilis — Benn, but it is 
widely separated from this form. 
A species of brocket, also known as " welbisiri," is 
frequently mentioned by bushmen in the colony, as 
being much smaller than the above, scarcely larger in 
fa6l than the fawn of the red deer while it possesses the 
lines of pale yellowish spots. This form is said never 
to lose the spots of the young stage, but to retain them 
throughout life. It would thus appear to be distinguish-
