104 TYRANNIDA. 
Supra griseo-brunneus ; capite nigricante, crista celata fulvo-aurantiaca ornato ; alis nigricantibus, tectricibus 
et secundariis internis sordide albo limbatis; cauda nigricante, rectricibus omnibus albido sstricte 
terminatis: subtus albus; subalaribus pallide flavo vix lavatis: rostro et pedibus nigris. Long. tota 9-5, 
ale 5:2, caudee 3°75, tarsi 0-9, rostri a rictu 1-65. (Descr. exempl. ex insula Mugeres. Mus. nostr.) 
Hab. Mexico, Mujeres I. (G. F. Gaumer?).—Cupa 13456; Bananas *. 
Mr. Gaumer’s collection from the island of Mujeres off the extreme north-eastern 
point of the promontory of Yucutan contained a single specimen of this species. The 
species had previously only been known from the island of Cuba, and with some doubt? 
from the island of Inagua. 
In Cuba, according to Gundlach *, 7. magnirostris is not an uncommon bird, being 
sedentary, and living in the woods, and on the plains where large trees grow. Its food 
consists of insects, young birds, and lizards, and it also preys to some extent on honey- 
bees. 
Its nest is composed of twigs, fibrous roots, and grasses, and is placed on a horizontal 
branch of some large tree, such as the Ceiba (Eriodendron); its eggs are like those of 
LT. griseus. 
MILVULUS. 
Milvulus, Swainson, Zool. Journ. iii. p. 165 (1827) (type Muscicapa tyrannus, Linn.) ; Sclater, Cat. 
Birds Brit. Mus. xiv. p. 277. 
The two species constituting the genus Milvulus have, as a common character, very 
elongated deeply forked tails, the bills also and the development of the supranasal 
feathers are similar, but in other respects they differ rather widely, not only in coloration 
but also in the way in which the outer quill-feathers in the males are reduced at their 
extremities. Thus in M. forficatus the outermost feather only is narrowed in this way, 
whereas in JW. tyrannus three are involved. 
The range of the two species is widely different, MW. forficatus being a bird of the 
prairies of South-western North America, Eastern Mexico, Guatemala, and thence south- 
wards as a rare visitor to Costa Rica. I. tyrannus, on the other hand, occurs in 
suitable open localities over the greater part of South America, and in Central America 
as far north as Southern Mexico.
