These 27 species include wide-ranging species such as 

 Milviilus tyrannus, Ceryle americana, Chamtppelia passerina, 

 andStrigcs (2), Accipitres (6)^ Herodioues (8), Ciconiidse (2), 

 Plataliidse (2), Phcenicopteridaj (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 but also of the lowlands, and comprise chiefly Passeres 

 (61) ; but the following orders are also represented : — Macro- 

 CHiRES [Trochilidse (7), Cypsclidse (1), Caprimulgidse (2)] ; 

 Pici (6); Coccyges [Galbulidte (1), Bucconidse (l),Cucu- 

 lidffi {!), Rhamphastidse (3), Capitouidte (1)] ; Psittaci (5); 

 Geranomorph^ [Psophiidae (1)] ; Limicol^ [Scolopacidae 

 (1)] ; Crypturi (1). 



The most strikingly peculiar of these endemic species are 

 Diglossa major, Cyanicterus venustus, Eucometis oleaginea, 

 Buarremon personatus,Agel(EUS imthurni, Chloropipo wiiforrnis, 

 Pipra suavissima, Lathria streptophora, Pipreola whitelyi, 

 Thamnophilus insignis, Campy lopterus hyperythrus, Avocet- 

 tula recurvirostris , Polymistria pavonina, Neomorphus puche- 

 rani, Conurus egregius, Brotogerys panychlora, Chrysotis 

 cceligena, &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.
