low chucking sound and the quality of the voice, as well as the color of the eyes, 

 the movement of the head, the physiognomy, the manner of huddling together, 

 especially at night, when they frequently sit two tiers deep, and often even three 

 deep all these things remind of the Florida ground-dove. 



They are quite like the chamsepelias also in their quickness of movement and 

 in their shyness. They work hard for the inside berth on the perch. They are

"Temminck and Knip (p. 115, Vol. I, pi. LII) show this species with bars over the whole under surface. Temminck gays 

 it has twelve tail feathers. 



REMARKS: I have not yet (Jan. 25, 1903) seen maugei, squamosa, or erythrothorax. The last of these is of much interest. 

 Squamosa is close to inca. Inca is apparently the simplest type, perhaps the parent form of all the others. All species, so 

 far as I have seen, have the long black spots or streaks in the Juvenal feathers. Scardafella stands lowest (young have the 

 black streaks), then the others follow in this order: maugei, striata, tranquilla, humeralis. Cuneata has made widest departure, 

 losing the crescentic bars. Humeralis stands highest of the barred species. 



In this table the arrangement of species is that of the author; the genera stand as arranged by Salvadori. The deci- 

 of the author would place the genera in the following order: Scardafella, Geopelia, Stictopelia (cuneata), Gj/mnojx/m. ED.
