posal of the writer. The nomenclature adopted in the present 
paper is in accordance with that of Mr. Ridgway, published in 
the Proceedings of the U. S. National Museum, III, pp. 163-246. 
In several instances the names are given in the Mandan and An- 
kara languages and marked respectively M and A. 
Hylocichla fuscescens (Steph.) Baird. — Wilson’s Thrush. 
Only a few specimens observed in the thickets between the 
1st and 5th. One was shot by an Indian boy, which gave me the 
opportunity for identification. 
Anthus ludovicianus (Gm.) Licht. — Titlark. 
Apparently not common. Only a few specimens noticed after 
the 10th. 
Neocorys spraguei (And.) Scl. — Sprague’s Titlark. 
Rather abundant during the earlier portion of the month in 
the vicinity of the grassy areas and the stubble fields ; that they 
appeared less numerous after the 15th or 20th may be attributed 
to the sudden cold weather, which compelled their departure from 
this region for a more southern one, or they may have tempora- 
rily sought refuge in the lower grassy terrace. 
Petrochelidon lunifrons (Say) Lawr. — Cliff Swallow. 
Not common. Several nests were found in the cliffs seven 
miles below the village, though from the number of birds observed 
there were undoubtedly more nests scattered in various places. 
Cotile riparia (Linn.) Boie. — Bank Swallow. 
A few individuals noticed north of the village at the sand- 
banks where the river formerly ran. 
Centrophanes ornatus (Towns.) Caban. — Chestnut-collared 
Longspur. 
Apparently not rare ; noticed in the stubble fields during the 
middle of the month. 
Rhyncophanes maccowni (Lawr.) Baird. — Macown’s Long- 
spur. 
Less common than the preceding. 
P ooecetes gramineus (Gm.) Baird. — Grass Finch. 
Rather common. Many of these birds were killed by the 
Indian boys who went out in small parties armed with bows and 
blunt arrows. They usually form a circle around the growth of
