 whole lower parts, except anal region and lower tail-coverts, and 

 occasionally even tingeing the latter), and also invading, more or less, 

 the crown, hind-neck, back, etc. ; or else, if absolutely restricted 

 within very definite limits, the tint not an intense carmine or crim-

' After a very careful comparison of more than a hundred adult males (in red or partially red plumage), I 

 am now quite convinced that the supposed race named Carpodaeus rhodocofptia by Cabanis (519a. €. /rontatia 

 rhnd fnlpm, Crimson Hou.^o Finch, of the A. 0. U. Check List) is entirely untenable. The easily recogniza- 

 ble differences of color (maximum extension of the red) which have led to its recognition prove to be, in the 

 light of this abundant new material, not correlative with locality, ajs supposed, but are evidently an individual 

 peculiarity, perhaps dependent upon age. I am not at all certain, however, that the Lower-Califomian bird 

 should not be separated. A considerable percentage of the specimens which I have been able to examine are 

 80 peculiar that nothing approaching them can be found in the very large series from other localities. These 

 peculiarities consist, (1) in the smaller general size, (2) rather more swollen bill, and {^) greater extension 

 of the red. This last peculiarity is carried to such an extreme that in all of the " Cape St. Lucas" specimens 

 the under tail-coverts are deeply tinged with jiink, while in some even the wing-bands are pinkish j in several 

 the pure deep madder-pink of the breast is continued backward over the belly and flanks, where the usual 

 dusky streaks are entirely obliterated. From the insufficient material at my command I am unable to form a 

 decided opinion in the matter, but the indications appear very strong that a local race, peculiar to the southern 

 portion of Lower California, will eventually have to bo recognized, in anticipation of which I propose the namo 

 Carpodiicua mejcicantu ruhtrrimut.
