Mr. P. L. Sclater on new species of Birds. 435 



sects ; the stomach of one which I shot contained nothing but the 

 heads, legs, and wing-cases of locusts ; that of a second was full of 

 large grasshoppers, and a lizard ; that of a third was filled with the 

 chrysalides 1 of butterflies. At the approach of evening the Warty 

 Ibis retires to thick trees to roost, uttering its loud and discordant 

 cry. It breeds during the months of February, March, April, May 

 and June, laying as many as three, and probably four eggs, of a pale 

 bluish-white, slightly streaked and spotted with pale brown, 2^^ in. 

 in length, by nearly ly'^^ in. in width. I found the nest of this Ibis 

 built on the top of apeepul tree (a species of Banian), and containing 

 three young birds, in the month of March.

On some new or little known Species of Birds in the 

 Derby Museum at Liverpool. 

 By Philip Lutley Sclater, M.A. 



The zoological collection of the late Earl of Derby, now at Liver- 

 pool, contains one of the largest and finest series of birds at present 

 in existence, many of the examples being valuable not only for their 

 rarity, but also as types of species described long ago by Latham in 

 his • General History' and other works, and which are hardly to be 

 recognized without examination of the original specimens. 



Mr. Thomas Moore, the present Curator, is busily engaged in 

 arranging this mass of materials, and affords every facility to those 

 who are anxious to inspect any of the objects committed to his care. 

 Among the birds I have had an opportunity of examining there 

 during a recent short visit are the following, which I venture to 

 characterize as new. 



1. CoNiROSTRUM ferrugineiventre, Sclatcr. 



C. ccBrulescenti-schistaceum, pileo et alis caudaque intus nigri- 

 cantibus : superciliis latis et elongatis albis: subtus intense 

 ferrugineum au t ferrugineo-rufum . 

 Long, tota 4*9, alae 2*75, caudae 2*0. 

 Hab. in Bolivia. 



This is a typical Conirostrum, and quite distinct, I think, from 

 any species hitherto described. The members of this genus with 

 which I am at present acquainted are — 



1. Conirostrum cinereum (Lafr. and d'Orb.) ; D'Orb. Voy. 

 Ois. pi. 59. fig. I. From Tacna in Peru and Sicasica in Bolivia. 



2. Conirostrum rufum, Lafr. Mag. de Zool. 1843. Dacnis 

 rufo-cinerea, Bp. Atti 6** Riun. Sc. It. 1845, p. 404, et Consp. 

 p. 401. From Bogota. 



3. Conirostrum sitticolor, Lafr. Rev. Zool, 1840, p. 102. 

 C. bicolor. Less.; Gray's Gen. pi. 34. From Bogota. 



4. Conirostrum albifrons, Lafr. R. Z. 1842, p. 301 ; Mag.
