1873. j SCLATER AND SALVIN ON VENEZUELAN BIRDS. 511 



3. On • some Venezuelan Birds collected by Mr. James M. 

 Spence. By P. L. Sclater, M.A., Ph.D., F.R.S., and 

 Osbert Salvin, M.A., F.Z.S. 



[Keceived April 30, 1873.] 



Mr. James M. Spence, F.R.G.S., of Manchester, has been kind 

 enough to submit to our examination a large collection of birds, 

 partly made by himself during a recent visit to Venezuela, and partly 

 obtained from a collector resident at Caraccas. 



The collection contains 23 mounted and over 300 unmounted 

 skins, referable to about 250 species. Only two of these prove to be 

 absolutely new to us ; but there are several others of sufficient 

 interest to induce us to offer to the Society the following notes on 

 them. 



1. Turdus olivater (Lafr.) ; Sclater, P. Z. S. 1859, p. 333. 



Mr. Spence's collection contains a single skin of this species, 

 which, so far as we at present know, is confined to the neighbour- 

 hood of Caraccas. 



2. Lochmias sororia, sp. nov. 



Similis L. nematurae, ex Brasilia, sed paulo major, superciliis 

 allis nullis, et maculis corporis in/erioribus minoribus et 

 magis elongatis: long, tola 6 - 2, alee 3, caudce 1*7, tarsi 1. 

 Hab. Venezuela (Spence). 



This is a northern representative of L. nematura of the wood- 

 region of Brazil, and is closely allied to that species, although easily 

 recognizable by the characters above given. 



3. Coccyzls landsbergi, Bp. Consp. i. p. 112; Sclater, P. Z. S. 

 1870, p. 169. 



A single skin of this rare Cuckoo in the collection is the only 

 example we have met with besides one in the British Museum (men- 

 tioned P. Z. S. 1870, p. 169). The species appears to be restricted 

 to Venezuela and the northern coast of Columbia. 



4. MlCRASTUR ZONOTHORAX (Cab.). 



Mr. Spence brings us a fine adult specimen of this northern form 

 of M. ruficollis, which agrees in every way with the points of di- 

 stinction pointed out by Dr. Cabanis*. We had previously only seen 

 immature examplesf. 



5. Ardea herodias, Linn. 



The occurrence of this northern species so far south as Venezuela 

 is a novelty to us. The most prevalent species in South America is 

 Ardea cocoi, which extends into Guiana (Schomb. Guian. iii. p. 752). 

 But A. herodias occurs in the Antilles and in the Galapagos (Scl. 

 & Salv. P. Z. S. 1870, p. 323).
