Vor full description, sec the General Report, (Vol. IX, P. E. R. Rcp'ts.) 
The western specimens difler so much from eastern, that Prof. Baird was induced to give them 
a different name provisionally, and when better known they may prove a distinct species. The chief 
c^ifi'crenccs arc: colors lighter; first quill intermediate between 6th and tth; second considerably 
shorter than fourth. Dr. Cooper's specimens measured : 
No. 1243. Shoalwater Bay, July 4, 1854. Length, 5.50; extent, 8.50 inches; 
No. 5920. Fort Stcilacoora. Length, 5.60; extent, 8.50; wing, 2.83; tail, 2.45. Both had 
the iris brown; bill black above, pale flesh color below; feet black. — C.
