cember.

Hirundo nigra, Gm. 8. N. i. p. 1025.

4. CypsELOIDES BOREALIS. 
Cypselus borealis, Kennerly, Pr. Acad. Phil. 1857, p. 202. 
Nephecetes niger, Baird, B. N. Am. p. 142. 
Niger unicolor, fronte canescente ; cauda quadrata: long. tota 
5'8, ale 6°5, caude 2:1, tarsi 0°5. ; 
Hab. Puget Sound, British Columbia. 
On the whole I am disposed to think this species will probably 
turn out different from the West-Indian C. niger, though my mate- 
rials are not at present sufficient to give accurate diagnoses of the 
two. 
Genus 3. CoLiocatia. 
Collocalia, G. R. Gray, List of Gen. 1840, p. 8. 
Salangana, Streubel, Isis, 1848, p. 368. 
I have paid no special attention to this group. Mr. Wallace, who 
has lately contributed an interesting article to these ‘ Proceedings’ * 
on the subject, recognizes six species, namely :— 
1. C. esculenéa, from Celebes, Timor, Moluccas, and Aru Islands, 
* See P. Z. 8. 1863, p. 382.
