are certainly quite as heavy, aud as broad at the points, as 

 those of the Griffon, but when the bird is circling they show 

 rather more curve at the shoulder ; a light spot towards the 

 ends of the quills, the warm reddish breast, aud the white 

 head were very conspicuous from below. The form, how- 

 ever, was that of a Vulture ; though this bird is at once 

 distinguished from any other species by its tail, which is very 

 long and continues broadening out for fully half its length, 

 from which point it narrows away to the sharp cuneate tip. 



This completes my winter's notes, for a subsequent expe- 

 dition to the marisma produced nothing more of novelty or 

 interest than has already been described. The results, I am 

 painfully aware, are meagre, in view of the ornithological 

 wealth of Southern Spain, and the exceptional opportunities 

 which, through the kindness of my friends in Jerez, I have 

 enjoyed for its exploration. The adverse weather is an ex- 

 tenuating circumstance; and in Spain a wet season signifies 

 more than words can convey, creating obstacles and difficulties 

 which must be seen to be believed.

 Aires, Argentine Republic. By Frank Withington. 

 TVith Notes by P. L. Sclater *, 



Lomas de Zamora is one of the many subdivisions, or Par- 

 tidos, as they are here called, into which the Province of 

 Buenos Aires is divided. It is some eight square leagues in 

 area, consisting of more or less rich and fertile pasture lands, 

 and, with the exception of an almost imperceptible undulation 



* [Mr. Witliiugton has most kiiidh^ placed at my disposal the specimens 

 upon which these notes are based. They are 150 in number, and are 

 referable to 92 species. I have inserted the scientific name of each 

 species, according to the numbers attached to the specimens in Mr. 

 Withington's MS., and have appended a few notes where necessary. 



As might have been expected, most of the species are well known 

 inhabitants of this district, but there are several of much interest, e. g,, 

 Agriornis striata, Pachyrhamphus polychropterus, Coccyzus ame?'ica7ms, 

 JButeo sioainsoni, aud the typical form of Falco pereyrimts. — P. L. S.]
