They contained aljout 12,000 skins^ representing 250 species. 

 Some of the new forms have been already described, while 

 four additional ones are here introduced for the first time, 

 viz. : — Ci/anerpes carulea chocoana from Colombia, Rham- 

 phocelus curho centralis from Brazil, Spizitornis parulus 

 patayoniciis from Argentina, and Lepidocolaptes lacryrniger 

 carabayce from S.E. Peru. Very valuable comments on 

 nomenclature and geographical distribution, together with 

 revisions of various groups of subspecific forms, make up the 

 rest of the paper, which is one of the most important con- 

 tributions to our knowledge of the avifauna of the eastern 

 slopes of the Peruvian Andes which has appeared tor some 

 time. 



The second paper, which also deals solely with neotropical 

 forms, contains revisions of nomenclature and synonymy, 

 A note on the first record of Hehuinthophlla leucubronchialis 

 in South America is of considerable interest, as this rare 

 little Warbler is believed by Mr. Faxon and other North 

 American naturalists to be a natural hybrid between 

 H. piniis and H. chrijsoptera. The South American example 

 was obtained near Merida in Venezuela, and is now in the 

 Tring Museum. 



Laubmami on Lesson's Types. 



[Kritische Uiitersucliuiigen iiber die Genotypfixierungen in Lesson's 

 ' Manuel d'Oinithologie,' 1828. Von Dr. A. Laubmann. Arch. Natur- 

 gesch. Jahrg. 8o, Abt. A, 1920, pp. 137-108.] 



In this laborious but useful work Dr. Laubmann has 

 carefully reviewed all the genera in Lesson's ' Manuel 

 d"Ornithologie,' and has shown that in many cases Lesson, 

 quite in accordance with the modern rules of Zoological 

 nomenclature, fixed the types of a good many genera where 

 the fixation has generally been attributed to Gray, whose 

 work was published later. This paper should be carefully 

 consulted by all who are interested in nomenclatural 

 Avurk.
