350 PROCEEDINGS OF. UNITED STATES NATIONAL MUSEUM. 
37. Tinnunculus sparverius (Linn.). 
Common. 
38. Buteo borealis calurus (Cass.). 
The Red Tailed Hawk, common in the low country, was quite as 
common in the mountains. 
39. Cathartes aura (Linn.). 
Very common and sociable. 
40. Columba fasciata (Say.) 
Abundant and breeding in February. Several nests were seen in 
oak trees, but not closely examined, however, they were so frail, twigs 
alone having been used in their construction. The eggs could be seen 
by looking through them from below. Their flesh was here excellent, 
notwithstanding they were subsisting principally upon the acorns of 
the deciduous oak (Quercus grisea). 
41. Melopelia leucoptera (Linn.). 
Very common. 
b. BIRDS OF THE LOWLANDS (VICINITY OF LA PAZ AND SOUTHWARD). 
Additional specimens from La Paz and south of it. 
1. Anthus cervinus (Pall.). (See page 156 of these proceedings. ) 
The single specimen was shot at San José del Cabo, on the bank of 
an irrigating ditch, February 7, 1885. Finding it in such a locality, at 
first sight I supposed it was a water thrush, as it was alone. 
I was unable afterward to find the species, although I persecuted a 
large flock of A. ludovicianus for several days after shooting it. 
2. Myiodioctes pusillus pileolatus (Pall.). 
Rare, but observed at several localities. 
3. Setophaga ruticilla (Linn.). 
Shot in a dense thicket at Miraflores February 24, 1883. An indi- 
vidual probably seen at La Paz in March following. 
4. Passerculus sandwichensis alaudinus (Bp.) 
Rare. 
(A specimen from San José del Cabo is peculiar in several respects, 
and may be a different species. For the present, however, I place it 
here, pending the examination of more specimens, should any be pro- 
cured.—h. h.] 
5. Pocecetes gramineus confinis Baird. 
Rare. 
6. Melospiza lincolni (Aud.). 
Rare. 
7. Ageleeus phceniceus (Linn.). 
Rare.
