HARPORHYNCHUS. 31 
fornia (H. redivivus). In Mexico, too, we find three species, two of which, H. curvirostris 
and HH. longirostris, 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 Turdide by many systematists, the position of Harporhynchus 
there is by no means assured. The short rounded wings of all the species, their scu- 
tellated tarsi, and peculiar curved bills are not at all Thrush-like, and point rather to 
the Troglodytide, 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, H. lecontit and H. 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 Harporhynchus 
rufus of the Eastern States 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 bill, in its 
darker cheeks, and the larger size and closer arrangement of the spots on the breast and
