Longitudo corporis, 5> unc. ; caudee, 2. By the kindness and liberality of Dr. Scouler of the Addisonian Museum of Glasgow, we are enabled to add a fourth species to the genus Lmicurus. This species (of which the specimen figured in Tab. XXVIII. is the only individual brought to Europe, with the exception of one in the British Museum,) has received the name of E. Scouleri in token of acknowledgement to the gentleman to whom we are indebted for it. The Enicurus Scouleri, which is the smallest of the genus, deviates in one character from the typical example ; the tail being of moderate length and slightly forked, while in the more typical species it assumes a scissar-like form, each part consisting of elongated feathers graduated at regular though remote distances. In habits and manners this pretty little bird resembles the rest of its genus ;—it is, however, by far the rarest, and occurs only in the remote districts of the Himalaya. The forehead and crown are white ; the occiput, neck, beak and breast jet black; the wings black with a broad white band across the coverts, each of the lesser quill-feathers being slightly edged with white; the rump is white crossed with an obscure line of black; the two outer tail-feathers white, the rest black; the under surface is white ; the bill black ; the tarsi pale flesh colour. The Plate represents a bird of the natural size.
