92. Stone on the Species of Psilorhiims. 



[On the Gemis Pdlorhinus, Riippell. By Witmer Stone. Proc. Acad. 

 Nat. Sci. Philad. 1891, p. 94,] 



After examiuing the specimens in the Museum o£ the 

 Academy of Natural Sciences of Philadelphia (which com- 

 prehend the type of Corvus vocifer'us, Cabot), and those 

 in the National Museum, Mr. Stone can recognize but two 

 species of Psihrhinus. These are P. morio, extending from 

 Teh uan tepee north to the Rio Grande valley, and P, mewi- 

 canus, ranging from Southern Mexico to Costa Rica, with 

 the possibility of a third distinct form (P. vociferus) in 

 Yucatan. The so-called P. cyanogenys of Sharpe is not 

 distinct from P. mexicanus. 



Messrs. Salvin and Godman have come to nearly the same 

 <x)nclusions (Biol. C.-A., Aves, i. p. 506). 



93. Von, den Steinen, on the Birds of South Georgia.

The second volume of the memoirs of the German Section 

 of the International Polar Commission of 188.2-83 contains 

 an excellent chapter on the Seals and Birds of South Georgia, 

 which is well worthy of attention. The German Expedition 

 passed a year in that remote island, from August 1882 to 

 September 1883, and had. full opportunities of studying its 

 animal life. A general account of the birds collected by the 

 Expedition was published by the late Dr. Pagenstecher in 

 1885 (see Ibis, 1885, p. 319). We have now a mass of 

 instructive details upon the ways and liabits of the 22 species 

 met with, illustrated by very characteristic sketches. We 

 may remark that the so-called Querquedula eatoni of South 

 Georgia has been determined by Dr. Cabanis to be different 

 from the true Q. eatoni of Kerguelen Island, and named 

 Querquedula antarctica (see J. f, O, 1888, p. 118).
