We learn from Hodgson and Jerdon that the Sangrok occupies the extensive forests of India to an altitude of three or four thousand feet above the sea, and that it leads a solitary life among the trees, from and around the branches of which it obtains the bees, wasps, beetles, and grasshoppers that constitute its principal food. The cry of this species is loud and harsh. According to the natives its eggs are deposited in holes of trees. * * * * * The ROLLERS (_Coracii_) are a race of tolerably large birds, for the most part remarkable on account of the variety of their colours, and the splendour of their plumage. All of them belong to the Eastern Hemisphere. As the leading features whereby this group is distinguished, we may enumerate their moderate-sized, or moderately long beak, which is strong and nearly straight, somewhat broad at its base, but compressed towards the tip, sharp-cutting at the edges, and bent down at the point; the legs are short and feeble, and the toes short. The wings are of moderate length, or long and tolerably broad. The tail is of medium length, sometimes truncate at its extremity, sometimes slightly rounded, and sometimes forked; occasionally, moreover, the two outer feathers are much longer than the rest. The plumage is somewhat harsh and rough, and the shafts of the feathers stiff. The predominant colours are green, blue, cinnamon-brown, and claret-red. The sexes differ but little, and the young very much resemble their parents. [Illustration: THE AUSTRALIAN BEE-EATER (_Cosmäerops ornatus_).] These birds generally inhabit dry, flat country, and are met with extensively throughout Europe, Asia, and Africa, but are scarce in Australia. Their usual residence is some solitary tree or high rock from which they can command an extensive field of vision, and in the holes and clefts of which they can build their nests. In such places they may generally be seen on the look-out for insects, which they catch and devour much in the same way as the Bee-eaters; at times they will dart down upon some poor mouse that happens to approach them too nearly, and occasionally they will snap up a lizard or other small game of that description, and will plunder a bird's nest in order to devour the young; but although they thus generally live on animal food, at certain seasons they have no objection to a vegetable diet, and will eat fruit. The flesh of some species is palatable, and they are consequently much sought after in some countries, either as food or on account of the beauty of their feathers. THE BLUE ROLLER.
