142. Tyrannus vociferans, Sw. Quart. Journ. Sc. 1826, 

 p. 273; Baird's Rep. p.l74. Tyrannus cassmn, Lawrence. (N.A.) 



Transmitted by Mr. Skinner from Salama, Vera Paz. 



143. Tyrannus melancholicus (Vieill.). 



This is a very abundant resident species about Dueiias. It 

 builds in the month of May an open nest, slight in texture 

 and flat 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 ol 

 red on a creamy-white ground. Some examples measure — axis 

 \\\ lines, diara. 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 (Gm.); 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.
