Hrrunpo aLpicuta (Bp.). White-throated Swallow. 
Two specimens of this species were shot on 19th August. 
By the 4th September these Swallows were plentiful along the 
river, and by 18th September they were pairing ; a month 
later they were more dispersed and not seen so plentifully. 
They feed principally over the marshes, but often rest upon 
the ant-heaps in the open country.

Trides dark umber; bill black ; tarsi and feet light dusky 
brown. 
This I take to be a species that I have not hitherto sent 
from this or any other locality; it feeds and is generally 
found in company with Cotile paludicola, Hirundo rustica,
