Recent Lateral 287 



No less than 1661 form are given in the list, oiu thousand more than are 

 contained in the Sclater and Salvin lit and thai included Mexico, Central 

 America and the Galapagos all of which are omitted iri the work befor< 

 l.i'ii pecii i accompanied by an English name which will be of gi 



tance to the museum curator in preparing exhibition labels. Some of 

 these 1 1 - 1 1 1 1 < • however are unduly cumbei ome while others conflict with 

 the Dames of common North American birds ■■> the use of ' Pewee' for 

 the Empidonax, of ' Marsh WK-n ' for Thryophilus, etc., we fully 



appreciate, however, the difficulty of finding English names for over four 

 ind birds. 



One matter of detail, which will of course be corrected in the synon 

 the failure to quote the name as originally published, bo that one cannot 

 rtain under what, generic name a species was described until the refer- 

 ence i- consulted. 'I here are also occasional lapses in stating the distribu- 

 og recently been working overa Venezuelan collection, we note 

 a number of instances where this country is omitted in the ranges of species 

 which are well known to occur there These are however trifling mati 

 which should Dot be seriously charged againsl a lis! admittedly only pre- 

 liminary and which is so excellent and helpful in other resp< i 



We Dote a Dumber of changes in Dames Some of those which affect 

 North American species are Colunibina for Chatmepelia, Podicepe for Colym- 

 Catharacia for Megalestrie Pluvialu for Charadrius, Charadriw for 

 alitii ■ Oxyechut • Ochthodromus, Tringa for Helodromas, Can 

 for Tringa, Nyroca for Marila, Oxyura for Erismatura, Mergansei for 

 Mergus, and Caprimirtgiu for Antrostomut Falco is divided, Cerch 

 being used for the Sparrow Hawks; while Pisobia is split into Pi&obia and 

 Heteropygia. We note also the use of Sida dactylatra Lesson L837 in place 

 of 8. cyanops, and Egretta thvla Molina 1782 for the Snowy Heron, while 

 the Black Vultuje, at leasl so far as South America is concerned, stand 

 Catharisla fcelam Some of these changes are undoubtedly necessary but 

 in other cases we think the A. 0. D Check-List is correct.
