I find, however, on comparing specimens from British 
Guiana in the McConnell collection as well as those in the 
British Museum, that they differ from the typical birds from 
Paraguay and southern Brazil, and I propose therefore to 
separate the Guiana bird as a subspecific form as follows :— 
Legatus albicollis successor, subsp. nov. 
Adult male. Differs from L. albicollis albicollis in being 
darker on the upper parts, the yellow on the under surface 
less bright, and smaller in size. Total length 146 mm., 
exposed culmen 10, wing 78, tail 60, tarsus 16. 
Adult female. Similar to adult male, but smaller. Wing 
71mm. 
Habitat. British Guiana, Surinam and Cayenne. 
The male and female types are in the McConnell collection. 
The late Dr. P. L. Sclater in 1856 considered that the 
Mexican bird was separable from the typical bird from 
Paraguay, and described it under the name of Llenia 
vartegata, P.Z.8. 1857, p. 297 (Cordova, Mexico; collected 
by Sallé: there is a second bird marked “type” by Sclater, 
which was collected at Jalapa, Mexico, by de Oca). But 
when compiling vol. xiv. of the ‘ Catalogue of the Birds in 
the British Museum’ he placed it as synonym of L. albicollis 
(Vieill.). Having examined the type, however, I am of 
opinion that it is quite a good form. It is distinguished 
from the Paraguay bird by its brighter coloration and larger 
measurements: wing 93-95mm. I propose therefore that 
Leyatus variegatus (Sclater) be used. 
Habitat. Mexico, Guatemala, Honduras, and Nicaragua. 
Further south there is another closely allied form, which I 
propose to separate under the following name :— 
Legatus variegatus nevagans, subsp. nov. 
Adult male. Differs from L. variegatus variegatus in being 
darker in general coloration and smaller in size. 
Total length 138 mm. 1 Can ce culmen 11, wing 85, tail 59, 
tarsus 15. 
Adult female. Similar to the adult male. Wing 76 mm.
