Amizilis bangsi (Costa Rica) ; Eupherusa eximia nelsoni 

 (Vera Cruz) ; Anthracothorax prevosti gracilirostris (Costa 

 Rica) ; Florisuga mellivora tobagensis (Tobago) . 



These diagnoses, like those in the former paper, are, no 

 doubt, in anticipation of the descriptions in the fifth volume 

 of Mr. Ridgway's work, which we hope will soon be pub- 

 lished. 



103. Riley on the Sharp-shinned Hawk. 



[On the Name and Synonymy of the Sharp-shinned Hawk. By J. H- 

 Riley. Proc. Biol. Soc. Washington, xxiii. p. 77.] 



Mr. Riley points out that if, as he suspects, Accipiter 

 fringilloides Vigors of Cuba is identical with Sparvius striatus 

 Vieill. of San Domingo, the species ought to bear the latter 

 specific name, as being ten years older. He has not yet been 

 able to compare specimens from the two islands. 



104. Thienemann on the Bird-Observatory of Rossitten. 

 [Die Vogelwarte Rossitten der Deutschen Omithologischen Gesell- 



schaft und das Kennzeichnen der Vogel. Von Dr. J. Thienemann. 

 Berlin, 1910. 8vo.] 



This little pamphlet of 16 pages contains full information 

 on the bird-observatory of Rossitten in the south-east corner 

 of the Baltic, founded by the German Ornithological Society 

 in 1901. It is well illustrated by maps and text- figures. 

 The institution is specially devoted to the question of migra- 

 tion. Full particulars are given respecting the mode of 

 labelling birds with aluminium rings, so that they may be 

 recognisable when captured elsewhere, and information as to 

 their direction of flight thus be obtained. As is well known, 

 Storks labelled at Rossitten have been captured in many 

 places in South Africa.
