TANAG-EIDJE. 



In our region seven species occur, three of which are peculiar to Mexico and 

 Guatemala ; three other peculiar species are found in Costa Eica and Panama, and the 

 only widely ranging one is C. alUtemporalis, which spreads from Costa Eica to Bolivia. 



The Central-American members of Chlorospingus are all very homogeneous ; but 

 some of the South-American species, such as the more slenderly built C. verticalis, are 

 decidedly aberrant. The stouter more robust species with which we here have to 

 do are very Fringilline in their general appearance ; the bill is conical and stout, but 

 less than in the next genus ; the maxillary notch is almost obsolete ; the wings are 

 moderately long, the third, fourth, and fifth quills being nearly equal ; the tail in the 

 more typical species is moderately long and slightly rounded ; olive is the prevailing 

 hue of the plumage, and the sexes are alike in colour.

We have been accustomed hitherto to include the Guatemalan Chlorospingus of this 

 form under the name of C. ophthalmicus, but we now find on closer examination that 

 the brown-headed Mexican bird is peculiar to that country, and that in Guatemala two 

 forms are found which are not only distinct from one another, but also from the bird 

 now under consideration. 



Chlorospingus ophthalmicus is a well-known bird in Mexico, chiefly in the upland 

 forests, but is also found in the hot country, according to Sumichrast ^. It only occurs 

 in the mountains of the southern parts of the Eepublic, where it has been met with by 

 many travellers.
