142. Tyrannus vociferans, Sw. Quart. Journ. Sc. 1826, 
p.273; Baird’s Rep. p.174. Tyrannus cassinii, Lawrence. (N.A.) 
Transmitted by Mr. Skinner from Salama, Vera Paz. 
143. Tyrannus melancholicus (Vieill.). 
This is a very abundant resident species about Duenas. It 
builds in the month of May an open nest, slight in texture 
and Hat in form. This structure is composed of sticks, with a 
few tine roots and horse-hair inside, and is usually placed at 
the end of a branch, at various heights from the ground. The 
eggs, generally four in number, are spotted with three shades ot 
red on a creamy-white ground. Some examples measure—axis 
1H lines, diam. 8 lines, but others are more rounded in form. 
144. Milvulus monachus, Hartl. R. Z. 1844, p. 214 : Mil- 
vulus tyrannus, Sclater, P. Z. S. 1856, p. 297. 
Scarcely different from the S. American M. tyrannus. It 
occurs at Estansuelas, a village on the road between Izabal and 
Guatemala. Mr. Skinner has transmitted examples of it, as 
also of 
145. Milvulus forficatus (6m.); PI. Enl. 677 ; Baird’s 
Rep. p. 169. 
146. Myiarchus crinitus (Linn.); Baird’s Rep. p. 178. 
(N.A.). 
Mr. Gould’s collection contains a Guatemalan skin of this 
species. 
147. Myiarchus lawrencii (Giraud); Baird’s Rep. p. 181. 
A common and resident species at Duenas, where its pecu¬ 
liarly melancholy note may frequently be heard. 
148. Myiarchus cinerascens (Lawr.) : M. mexicanus , 
Baird’s Rep. p. 179. 
Also found at Duenas; but it is by no means of such frequent 
occurrence. Examples were procured at Livingston, at the 
mouth of the Rio Dulce, in December. We are not quite con¬ 
vinced of the identity of this bird with Dr. Kaup’s Tyrannula 
mexicana (P. Z. S. 1851, p. 51), to which Professor Baird has 
united it.
