six species at present known, only eighteen or twenty 
barely straggle within the boundaries of the North Ame- 
rican or Nearctic Region. 
Excluding the birds of Paradise, no other family con- 
tains so many curious and strangely adorned forms 
as the Humming-birds. Among the more remarkable 
species may be mentioned the unique Loddigesia mirabilis, 
Lophornis Helenz, the Short-tailed Wood Star, Aces- 
trura micrura, Sappho sparganura, and the singular 
Spathura underwood: with its snow white “ tibial tufts.” 
Notable British Guiana forms are the King Humming- 
bird ZYopaza pella, Discura longicauda and Campy- 
lopterus largipennis. The last is remarkable for the 
singular development of the first primary in the males, 
the shaft of which is abnormally enlarged. 
In the Islands, three lovely little humming-birds be- 
longing to the Genus Be//ona are met with ;—One &. 
extlis, an elegant little creature with a glittering blue 
crest, is very common in the Island of Anguilla, fre- 
quenting the Loblolly trees (Pisonia subcordata) and 
nesting amongst the branches. 
Next to the humming-birds in point of beauty, come 
the Cotingas (Cotingidz), the Tanagers (Tanagridz) and 
the Manakins (Pzprzdz) groups rich in remarkable and 
beautiful species. The first two families are stri€tly 
Neotropical in their range, but the last occurs in the 
Nearétic Region as well, though the species are most 
numerous within Neotropical limits, 
About one hundred and ten species of Cotingas have 
at present been recorded, some two dozen of which are 
natives of British Guiana, The family embraces such 
splendid forms as the Cock-of-the Rock, Rupicola crocea
