THE COMMON GREY HORNBILL.

Length, 22 to 25 ; expanse, 25 to 32; wing, 7.5 to 8.7; tail, 10 to 12; tarsus, 1.7 ; bill from gape, 3.5 to 4.25.

Bill and casque dusky; the tips and ridges of both mandibles whitish ; casque low and compressed, the ridge prolonged anteriorly to a very acute angle, and the hind part concealed by the feathers of the forehead (which bend down over it) and not extending backward over the crown.

In the female the casque is lower, more depressed and the sharp pointed horn is wanting; irides red-brown ; feet dark plumbeous.

Plumage grey, paler below, and from the breast gradually albescent ; ear-coverts darker cinereous, and a light streak over the eye and ear-coverts ; primaries and secondaries dusky black, the latter margined with grey, all except the two first tipped white, with a brownish-white streak on the outer web ; tail black near the end, 'tipped white.

In the female and in immature bird the first six or seven primaries want the white tips entirely, while on all but the first two, the whitish streaks are much more developed and conspicuous than in the adult male.

The Common Grey Hornbill does not occur in Sind, and has only been doubtfully recorded from the Deccan ; it is not uncommon at Mount Aboo and forests at foot, and is very common at and near Mhow and Neemuch ; :- indeed, generally speaking, it is not uncommon in all the well-wooded portions of Rajpootana, Guzerat, and Central India.
