Following is a list of the specimeus examined 



a. rufivirgata. 



* The fii'&t number indioatos the length of the bill from the nostril; the second, it.s depth through the 

 base. 



ji. crassiroslris. 



tThi.s specimen is somewhat intermediate in coloration between rufivirgata and cra.5«iro«tri«, but 

 seems decidedly nearer the tormoi'. It (iiffei-s from both, however, in tne very sharp detinition of the 

 stripes on the he:id, which, however, are clear, unifo m chestnut, and in the bright h\iSyellow cast of 

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

 resent a fourth race, peculiar to Western Mexico.
