from British Guiana. 
These 27 species include wide-ranging species such as 
Milvulus tyrannus, Ceryle americana, Chamcppelia passerina , 
and Striges (2), Accipitres (6), Herodiones (8), Ciconiidse (2), 
Plataliidse (2), Phoenicopteridse (1), Rallidse (2), none of 
them calling for special comment. 
12. Species endemic in Guiana. 
Total number.92 
or about 16 per cent, of the 589 Guiana species. 
These 92 species include birds not only of the mountain 
ranges hut also of the lowlands, and comprise chiefly Passeres 
(61); but the following orders are also represented :— Macro- 
chires [Trochilidse (7), Cypselidse (1), Caprimulgidse (2)] ; 
Pici (6) ; Coccyges [Galbulidse (1), Bucconidse (1), Cucu- 
lidse (1), Rhamphastidse (3), Capitonidse (1)] ; Psittaci (5); 
GERANOMORPHiE [Psophiidse (1)] ; Limicol^i [Scolopacidse 
(1)] ; Crypturi (1). 
The most strikingly peculiar of these endemic species are 
Diglossa major, Cyanicterus venustus, Eucometis oleaginea, 
Buarremonpersonatus,Agelaeus imthurni, Chloropipo uniformis, 
Pipra suavissima, Lathria streptophora, Pipreola whitelyi, 
Thamnophilus insignis, Campylopterus hyperythrus, AvoceU 
tula recurvirostris, Polymistria pavonina, Neomorphus puche- 
rani, Conurus egregius, Brotogerys panychlora, Chrysotis 
coeligena, &c. 
One point remains to be noticed, and that is the relation¬ 
ship of the birds of this portion of Guiana to those of 
Cayenne, the eastern extremity of the whole district. In 
the vast majority of cases the same species inhabit both 
portions of Guiana, showing no change whatever; but the 
facts of Pipra suavissima of British Guiana taking the place 
of P. serena of Cayenne, and of the form of Tachyphonus 
cristatus in Cayenne being rather that of the Amazons valley 
and Venezuela than that of British Guiana, suggest that when 
the two districts are closely compared other similar differences 
may be discovered. Unfortunately we have at present 
nothing like a complete list of Cayenne birds to enable us to 
make a full comparison.
