Dr. Schlegel has pointed out (Musée des Pays-Bas, Aves, Momotus, 
p- 8) the slight distinctions which separate this race from the Mo- 
motus martit of the Amazon valley. The present bird occurs near 
Santa Martha (Verreauzx), on the Nercua River, on the eastern side of 
the Andes of New Granada (Cassin), and as far north as Panama.

Panama birds do not differ from the Guatemalan B. dysoni; and 
B. leucocrissus, Sclater, of Ecuador is hardly separable.

Agrees with Sclater’s types, except that the breast-band is rather 
wider in our Panama specimen.

It is very probable that these so-called species may be sexual forms 
of the same bird; but we are not yet ina position to explain the 
matter fully. 
In Mr. M‘Leannan’s series the cinnamon-coloured birds are 
labelled males, and those with pale plumage females. Wherever 
one so-called species is found, the corresponding one also occurs. 
In Vera Paz we find M. vere-pacis and M. inornata in the same 
localities.
