Bulletin American Museum of Natural History. [Vol. XXXIV, 
that the numerous remaining genera of the subfamily will be found to agree 
with them in this respect. 
Patagona gigas 
Chlorostilbon sp, 
Colibri iolotus 
Oreotrochilus pichincha 
Anthracothorax gramineus 
Chrysolampis elatus 
Ensifera ensifera 
Boissoneaua flavescens 
Heliothryx sp. 
Of the Lophornithine I have examined Lophornis helene, L. ornatus and 
L. magnifica and find them diastataxic. 
Here, then, is an additional character separating the Phcoethornithinse 
from the rest of the family. 
For convenience of reference a list is given below showing our present 
knowledge regarding the occurrence of the diastataxic and eutaxic types 
of wing among Carinate birds. 
There is little doubt that further exceptions 
will be discovered of eutaxic forms in the diastataxic groups. 
Pygopodes 
Tubinares 
Herodiones 
Steganopodes 
Phoenicopteres 
Anseres 
Accipitres 
Ralli 
Grues veri 
Otides 
Lari 
Alcs 
Pterocletes 
Megapodes 
Psittaci 
Striges 
Caprimulgi 
Universally Diastataxic.

(Flamingoes) 
(Swans, Ducks, Geese)

(Rails) 
(True Cranes, Limpkin)

Anhimse (Screamers) 
Turnices (Hemipodes) 
Coracize - (Rollers) 
Halcyones (Kingfishers) 
Cypseli (Swifts) 
Trochili (Hummingbirds) 
Numerous genera of each style. 
Philohela alone known to be eutaxic. 
Chauna diastataxic, Anhima eutaxic. 
Pedionomus diastataxic, Turnizx eutaxic. 
Coracias and Eurystomus diastataxic, Corapitia 
probably eutaxic. 
Several genera of each style. 
Mostly eutaxic, Streptoprocne and Collocalia said 
to be diastataxic. Dendrochelidonide (all?) 
diastataxic. 
Phethornithine eutaxic, all others diastataxic.
