BIRDS.

The Hinindinidae, or Swallows, are true cosmopolites. Al- 
though they do not range quite so far north (except as stragglers) 
as a few of the extreme polar birds, yet they pass beyond the 
Arctic Circle both in America and Europe, Cotyle rvparia having 
been observed in the Parry Islands, while Rirundo rustica has 
been seen both in Spitzbergen and Nova Zembla. Cotyle riparia 
and Chelidon urbica also breed in great numbers in northern 
Lapland, latitude 67° to 70° north. Many of the species also, 
have an enormous range, the common swallow (Rirundo rustica) 
inhabiting Europe, Asia and Africa, from Lapland to the Cape of 
Good Hope and to the Moluccas. The genera of swallows are 
not well determined, a number having been established of which 
the value is uncertain. I admit the following, referring by 
numbers to the Hand List : — 
(215 — 221 226 — 228 ) Rirundo (40 sp.), the range of the entire 
family ; ( 222 223 ) Psalidoprogne (10 sp.), Tropical and South Africa ; 
( 224 ) Phedina (1 sp.), Madagascar and Mascarene Islands ; ( 225 ) 
Petrochdidon (5 sp.), North and South America and Cape of Good 
Hope; (229 — 232 • 234 ) Attimra (8 sp.), the Neotropical region and 
? Australia ; ( 235 237 ) Cotyle (11 sp,), Europe, India, Africa, North 
America, Antilles and Ecuador ; ( 236 ) Btelgidopteryx (5 sp.), La 
Plata to United States ; ( 238 and 239 ) Chelidon (6 sp.), Pahearctic 
region, Nepal, Borneo ; ( 24 ° ~ 242 ) Progne (5 sp.), all North and 
South America.

The Icteridae, or American hang-nests, range over the whole 
continent, from Patagonia and the Falkland Islands to the 
Arctic Circle. Only about 20 species inhabit the Nearctic 
region, while, as usual with exclusively American families, the 
larger proportion of the genera and species are found in the
