Part I was A. Hyatt on Spheniscidce, op. cit, xiv, p. 237. — A simple cat.ilogue, -with refer- 

 ence to the locality, when known, of each specimen, which, is mentioned by the Society's 

 number, the original number of the Lafresnaye Collection, when any, being also given ; num- 

 bers of species according to Gray's Hand List also affixed. Ehynchofalco, p. 46 ; Anterior, p. 

 63, nn. subgg. Cf. Coues, Am. Nat, 1874, pp. 541-546. 



1873. RiDGWAY, R. Revision of the Falconine Genera, Micrastur, Geranospiza and 

 Rupornis, and the Strigine Genus, Glaucidium. <^ P^-oe. Bost. Soc.Nat. Hist, 

 xvi, 1873, pp. 73-106. 



Published as an "Appendix" to the author's catalogue of the Falconidce of the Boston So- 

 ciety, torn, cit., pp. 43-72. An elaborate article, with characters and synonymy of the genera 

 and species, analytical tables, etc., based upon examination of an unusually large series of 

 specimens. Micrastur, 5 spp. ; Geranospiza, 2 spp. ; Rupornis, 2 spp. ; Glaucidium, 8 spp. ; 

 besides several "varieties" of each of these genera excepting the first. There is much recti- 

 fication of synonymy according to the views of the writer, which are not in entire accord with 

 those of other authors. Cf. Coues, Am. Nat, 1874. 



Glaucidium is treated on pp. 91-106. This is the first elaborate monograph of the genus, 

 and led to the subsequent revisions of the group by Mr. Sharpe (1875) and Mr. Eidgway (1876). 

 (See antea under Strigidce.) The species allowed in this monograph are G. passerinum var. 

 ealifornicurh ( — (?. gnoma). G. pumilum, G. lansbergii (=rufous phase of G. jardinii), G. 

 jardinii, G. ferrugineum, G.infuscatum (=^G. ferrugineum), G. infuscatum var. gnoma (=G. 

 ferrugineum), G. nanum-, and G. siju. G. lansbergii is described as new, (but has been deter- 

 mined to be the rufous phase of G. jardinii). — The rectifications here given in parenthesis are 

 derived from the author's later study. 

 1873. SCHLEGEL, H. Revue de la Collection des Oiseaux de Proie faisant partie du 

 Mu8€e des Pays-Bas. < Mus. Nat. HisL Pays-Bas, 10^ livr. , Juillet 1873, pp. 1- 

 156. 



The author here reviews the whole subject, which he had previously gone over in 1862-3, 

 but has not apparently much to add to science, though noting the increase of the Museum.
