 Government, where, however, the Red-spotted form un-

S9. Emerson on the Birds of Southern California. 



[Ornithological Observations in San Diego County. By W. Otto 

 Emerson. Bull. California Acad. Sci. vol. ii. p. 419.] 



The present paper is intended to show the relative abun- 

 dance of the birds found on the Volcano Mountains, where the 

 author was storm-bound from January to March 1884, and 

 those of the Poway Valley in winter and spring. The Volcano 

 Mountains, rising about 5000 feet above sea-level, are about 

 seventy-five miles north-east of San Diego, in Southern 

 California, and 46 species were noticed there. From Poway 

 Valley, twenty-two miles north of San Diego, 63 species are 

 recorded. 



40. Ernst on the Birds of the Caracas Museum. 



[Catalogo de las Aves en el Museo Nacional de Caracas. For A. 

 Ernst, Director del Museo. Revista Cieutifica de la Uuiversidad Central 

 de Venezuela, vol. i. p. 25.] 



Dr. Ernst gives us a catalogue of the species of birds repre- 

 sented in the National Museum of Venezuela at Caracas. 

 These are 339 in number, mostly native, but some extra- 

 neous. The Spanish vernacular names are usually men- 

 tioned, but the series of Venezuelan species is by no means 

 complete. We observe that the Condor {Sarcorhamphus 

 gryphus) is stated to occur in the Andes of Merida. The 

 Chauna of Venezuela is not C. chavaria, as here stated, but 

 C. derbiana. A complete list of Venezuelan birds is still a 

 desideratum.
