and back black ; the upper and under tail-coverts bright rufous ; the 

 \vings and tail dark brown ; two streaks of black, one from the gape 

 and the other (rather short) from the base of the bill ; the throat, 

 breast and middle of the abdomen rufous white, varied with rufous 

 brown. 



Totai length, 5 inches ; bill, from gape, 1 inch ; -vving, 2 inches 2 

 lines ; tarsi, 1 inch. 



This proposed division differs from the typical form of Certhia by 

 the length and form of the bill and the position and form of the nos- 

 trils, while the extreme shortness of the tail at once points out a great 

 dissimilarity from those species that properly belong to the above- 

 mentioned genus. 



I have also before me another bird that appears to belong to the 

 šame subfamily, \vhich I shall form into a distinct genus, under the 

 name of . 



Salpornis. 



Rostrum longum latum basi subdepressum, per totam longitudinem 

 curvatum ; lateribus a naribus fortiter compressis. Gonys elonga- 

 tus, curvatus. Nares laterales, anticė in sulco lato brevi siti, 

 apertura magna nuda. AIcb longissimse, usque ad caudse apicem 

 ferė attingentes, acutse, remige prima brevissima, secunda ferė 

 longitudinis tertise quartBeque, quae 8equales et omnium longissimae. 

 Cauda breviuscula, quadrata, rectricum apicibus rotundatis. Tarsi 

 medio digito breviores, squamis latis muniti. Digiti longi, fortes, 

 intimo quam extimo breviore basi param coadunato, extimo lon- 

 gius coadunato ; postico lougo, forti, ungue curvato armato. 

 The type of this proposed genus is already described by Major 

 Franklin in the Proceedings of the Society under the name of Certhia 

 spilonota (Proc. 1831, p. 121). 



The difFerences exhibited between this and the former genus are 

 at once seen in the form of the wings, which are lengthened and 

 pointed, and of the tail, which has the ends of the feathers slightly 

 rounded. These characters are likę those of Tichodroma, -vvhile the 

 form of the bill and feet are similar to those of the genus proposed 



The specimen of Caulodromus was kindlylent me by J. K. (jrace, 

 Esq., who procured it in Darjeeling : that of Salpornis was presented 

 by B. H. Hodgson, Esq. to the British Museum, and forms part of a 

 coUection from Behar.

 This is one of the best-defined groups of the family, and is distin- 

 guished by several peculiarities, the principai of \vhich are the greatly 

 developed ear-coverts and their blue colour, and the similarity in the 

 colouring of the sexes, the femules possessing all the brilliancy of
