5. arguta ; they are of a light purple or rich vinous brown ground

The nidification of this bird is similar to the preceding species, 
and the same may be said of all members of the genus. The eggs 
in a number of sets of live species of the genus now before me, 
show very little variation either in form or colour, and it would 
be difficult, if possible at all, to single out those of one species from 
another. Specimens that have been recently taken are of a 
much brighter and deeper colour. 
The Sooty Crow-shrike lays from three to four eggs for a 
sitting, varying in shape from a short to a long oval, of a pale 
chocolate or vinous-brown ground colour, and marked all over 
with blotches of light-brown ; in one specimen (a) the markings 
are very small and confined to the larger end. Length (A) 1-63 
x 1-2 inch ; (B) 1-75 x 1T8 inch ; (C) L73 x 1-22 inch. 
This species breeds during the months of August, September, 
and October.
