certainly a good representation of Montagu's Harrier. We 

 can therefore rest assumed that the correct name for this 

 species is Circus py gar gus (Linn.). 



"1 further wish to draw your attention to the great 

 differences which exist in the figures of other birds in these 

 three copies of Albin's work. These variations in the 

 coloration of the plates ought to make us very careful how 

 we apply names founded by the early writers on figures only; 

 for it is quite conceivable that the plates in other books, such 

 as Edwards's ' Gleanings ' and some of the early works, may 

 vary in a similar way in different copies." 



Dr. Ernst Hartert exhibited and described examples of 

 the following new subspecies of birds : — 



Icterus xanthornus trinitatis, subsp. n. 



This island race is nearest to /. x. heliueides Clark from 

 the island of Margarita, but the wings are shorter and the 

 distal ends of the primaries have no white edges to the outer 

 webs; and in the majority of specimens the bill is smaller. 

 Wing in ten adult males 96-99*5 mm., as compared with 

 101 in the male of I. x. helioeides. I. x. trinitatis differs 

 from /. x. xanthornus from Colombia, Venezuela, and the 

 Guianas in having a larger bill, longer wings, and in lacking 

 the white edges to the distal halves of the outer webs of the 

 primaries; also the white markings on the wing-coverts are 

 more restricted. In some specimens of /. x. trinitatis 

 a faint indication of white edges to the distal portions 

 of the primaries can be traced. Some specimens from 

 N.E. Venezuela have somewhat larger bills and longer 

 wings than usual, thus approaching the Trinidad form ; 

 but the majority, even from N.E. Venezuela, are readily 

 distinguishable.
