4, On a Nev\^ Species of Dendrochelidon, or Tree Swift. 

 By John Gould, Esq., F.R.S., etc. 



The highly interesting group of Tree Swifts forming the genus 

 Dendrochelidon has recently been augmented by the discovery of a 

 new species in Celebes by Mr. Wallace— the fifth of the form with 

 which we are now acquainted — the four previously known being the 

 splendid D. mystaceus of New Guinea and the Aru Islands, the B. 

 comatus of Manilla and Malasia, the old D. klecho of Java, and the 

 D. coronatus of India. The new species (which is the second in 

 size, being only exceeded in this respect by the B. mystaceus) is, as 

 already stated, from Macassar, Celebes ; it is most nearly allied to 

 the D. comatus and D. klecho, but differs from both those birds in 

 its much larger size, and in the deep-blue colouring of its shoulders 

 and wings. This bird, which I have named wallacii in honour of 

 its discoverer, may be thus described : — 



Dendrochelidon wallacii. 



Crown of the head deep green, with steel-blue reflexions ; lores 

 black ; over each eye an indistinct stripe of greyish-white ; sides and 

 back of the neck and the upper part of the back green, passing into 

 grey on the lower part of the back and rump, which colour again 

 passes into the bluish-green of the upper tail-coverts ; shoulders 

 blue, with reflexions of green ; primaries bluish-black, with green 

 reflexions ; tertiaries greyish -white ; tail bluish-black ; throat and 

 under surface grey, passing into greyish-white on the vent and under 

 tail-coverts ; bill and feet olive. 



Total length 1 inches ; bill, from gape to tip, i ; wing 7|, 

 tail 5i. 



Remark. — The usual chestnut-coloured mark immediately below 

 the ear, indicative of the male, occurs in this as in the other mem- 

 bers of the genus. 



Mr. Gould exhibited a specimen of Critliragra brasiliensis, a na- 

 tive of Brazil, forwarded to him by Mr. Stone of Brighthampton, 

 which was shot in October last at Bampton in Oxfordshire, whilst 

 in company with a flock of Sparrows. It had in all probability been 

 brought to this country caged, but had evidently moulted since ob- 

 taining its freedom.
