Recently published Ornithological Works. 391 



described by Mr. Ridgway in 1881 (Proc. U.S. Nat. Mus. iv. 

 p. 336) as Acanthidops bairdi, and referred to the Dendro- 

 colaptidse,, but considered by the Editor (see Ibis, 188 J<, 

 p. 243) to belong to the Fringillidse. The adult male be- 

 trays its affinities more obviously, being closely similar in 

 coloration to Haplospiza unicolor. It is possibly the same as 

 Haplospiza uniformis o£ Mexico (Biol. C.-A., Aves, i. p. 366), 

 or at any rate a nearly allied species. But in Mr, Hidgway's 

 opinion Acanthidops should be kept generically distinct from 

 Haplospiza. 



84. Salvadori on Pallas's Sand Grouse in Italy.

 maso Salvadori. Boll. Mus. Zool. ed Anat. Comp. iii. no. 52.] 



This is a supplement to Count Salvadori^s previous paper on 

 the same subject [cf. supra, p. 130), and contains rectifica- 

 tions of and additions to the former list of the occurrences of 

 Syrrhaptes in Italy in the spring of 1888. Between the 

 24th April and 9th September of that year about 102 indi- 

 viduals were observed and 43 taken, of which 17 were 

 preserved. 



85. Sclater and Hudson's 'Argentine Ornithology.' 



[Argentine Ornitlaology. A descriptive Catalogue of the Birds of the 

 Argentine Republic. By P. L. Sclater, M.A., Ph.D., F.R.S., &c. With 

 Notes on their Habits by W. H. Hudson, C.M.Z.S., late of Buenos Ayres. 

 Vol. II. Ptoyal 8vo. London : 1889.] 



The issue of the second volume of ' Argentine Ornithology,' 

 which was published in April last, renders this work com- 

 plete. The second volume contains an account of all the 

 Orders of Birds met with within the Argentine Republic, 

 except the Passeres, which were treated of in the first volume, 

 together with the aj)pendix, index, and introduction. The 

 total number of species recognized as at present known to 

 belong to the Argentine avifauna is 434, to which, no doubt, 

 considerable additions will be made when the northern pro- 

 vinces of the Federation arc more completely explored.
