Stone appears to have well performed his task, as will be 

 seen by the volume now before us, which is principally oc- 

 cupied by an annotated list of the birds of Eastern Pennsyl- 

 vania and New Jersey. The species recognized as occurring 

 within these limits are 352 in number. A complete biblio- 

 graphy and illustrative maps are added. 



124. Suchetet on the Bimaculated Duck. 



[Histoire du Bimaculated Duck de Pennant, confondu longtemx^s avec 

 VAnas glocitans de Pallas ; et Notes sur plusieurs autres oiseaux du meme 

 genre. Par Andre Suchetet. Pp. 48. 8vo. Lille, 1894.] 



The author, who is already well known for his writings on 

 hybrids, especially among the Anatidfe, devotes 14 pages to 

 exposing the errors committed by Pennant and his successors

 Ducks are discussed. Two coloured plates by Keulemans 

 are given : the first representing Degland's bird in the Douai 

 Museum, supposed to be a cross between Anas boscas 

 and Querquedula crecca ; the second, an apparent hybrid 

 between A. boscas and Chaulelasmus streperus, in the col- 

 lection of ISIr. E. Hart, of Christchurch, Hants.

 Bull. Madras Govern. Mus. no. 3, 1895.] 



Mr. Edgar Thurston, Superintendent of the Madras Govern- 

 ment Museum, has kindly sent us a copy of the second 

 edition of his excellent account of Ramesvaram Island, on 

 the line of Adam's Bridge, between India and Ceylon. 

 Marine animals are, of course, its principal product, and it 

 would seem to be a perfect spot for such a marine biological 

 station as has been talked of in India. But Mr. Thurston 

 procured there a certain number of birds, of which he gives
