exclusive of the tail, 33 inches ; length of the tail, 5 inches ; 

 greatest circumference of the body, 29 inches. The superior 

 or common horns are placed on the forehead, and are four or 

 five inches in length, slightly diverging, subulate, conical, and a 

 little directed forwards ; the spurious horns are placed between 

 the eyes, are less than the superior, and slightly diverging. The 

 upper parts of the body are of a bright bay colour ; the under 

 parts dusky white, with a few yellow nairs. Such were the cha- 

 racters of the male specimen described: the female has no 

 horns, and is less bright in colour; this distinction in colour 

 appears to be permanent, for it continued, during four years, in 

 a pair possessed by the author : they bred during this period, 

 two at a birth, and the young were similarly distinguished in 

 colour. The male was very fierce in the rutting season, and 

 though partly domesticated, continued to be so ; at this time 

 the feeder could only approach the verge of the circle which 

 the rope securing the animal permitted him to describe. 



Description of Buceros. — Hornbill without the helmet or 

 rostral appendage, with a pendant gular sac, or pouch. By the 

 same. 



The length of this bird was 36^ inches, of which the tail 

 measured 12 inches, and the bill 7 inches; the distance between 

 the extremities of its wings, when spread, was 53 inches ; the re- 

 gular appendage, marked with yellow vertical lines, and with a 

 bright blue mark, was 3i inches long, and 3 inches wide r 

 weight of the bird, when living, five pounds and a quarter. The 

 eyes large, surrounded with a naked circle, and with some 

 bristly feathers, the pupil large and black ; the irides marked 

 with four concentric circles, of different widths, and of the follow- 

 ing colours respectively, reckoning from the innermost, white, 

 brown, orange, and black. The auditory apertures behind the 

 eyes, circular, concealed when the feathers are in their natural 

 position, but plainly visible when they are turned up. 



Plumage of the body black, with shades of olive-green when 

 viewed in a strong hght. This bird is a native of the woods 

 about Chittagong and bylhet ; and resembles the Calao Javan of 

 Le Vaillant, as described by Shaw : the specimen described in 

 this paper lived two years caged, and died while moulting. 



The reading of Dr. Hamilton's Commentary on the second part 

 of the Hortus Malabaricus, was continued. 



In this elaborate commentary, Dr. Hamilton traces the plants 

 described by Kheede, in the second part of the Hortus Malaba- 

 ricus, through the works ofsucceeding writers, down to Linnseus 

 and later botanists ; giving their various synonyma, and compar- 

 ing their characters as described by the different authors ; occa- 

 sionally suggesting new appropriations of the names in the H. M. 

 and showing, that in some instances several species described 

 in that work have been erroneously confounded together as 

 one; while ia others one real species has been divided into
