fomia {H. redivivus). In Mexico, too, we find three species, two of which, H. curvirostris 

 and H. longirosfris, have a wide range, the third, H. ocellatus, being restricted to the 

 State of Oaxaca. The fourth species found in our region is peculiar to the island of 

 Socorro. 



The genus has been carefully studied by Dr. Coues, who has written several papers 

 on the subject. His latest views will be found in his recently published ' Birds of the 

 Colorado Valley.' 



Though placed in the Turdidae by many systematists, the position of Earporhynchus 

 there is by no means assured. The short rounded wings of all the species, their scu- 

 tellated tarsi, and peculiar curved bUls are not at all Thrush-like, and point rather to 

 the Troglodytidae, in which family they have been placed by Prof. Cabanis. A close 

 examination of the internal structure of some member of the genus alone can afford 

 good grounds for settling the point. 



Besides the four species mentioned below, two others, E. lecontu and E. crissalis, 

 occur on our frontier in the valley of the Gila, and may be found to pass to the Mexican 

 side. An account of both these birds will be found in Dr. Coues's work already 

 referred to.

The position of this Mocking-bird in its relationship to the well-known Earporhynchus 

 rufus of the Eastern Spates of America has long been a matter of doubt, most American 

 authors "^ ^ considering it to be a local form of that species, which no doubt it is, differing 

 in the duller tint of the upper plumage, and in the greater curvature of the biU, in its 

 darker cheeks, and the larger size and closer arrangement of the spots on the breast and
