tThis specimen is somewhat intermediate in coloration between rufivirgata and crassirostris, but 

 seems decidedly nearer the former. It differs from both, however, in the very sharp definition of the 

 stripes on the head, which, however, are clear, uniform chestnut, and in the bright buff yellow cast of 

 the crissum and tibia. It is quite possible that this specimen, which is not in good condition, may rep- 

 resent a fourth race, peculiar to Western Mexico.
