Nore.—A fourth Mexican species is 8. parva (Lawr.),—Spermophila parva Lawr., Ann. N, Y. Ac. Sci. ii, 
1883, 382),—from Tehuantepec. I have seen the type, which is a female or young bird, and believe it to be a 
very distinct species, the adult male of which is unknown. The type being now in Europe, I am unfortunately 
not able to include the species in the above synopsis.
