gray, darker than in A. herodias, with a similar throat line of white, blaolr, 

 and rufous. Under wing-ooverts streaked with white ; rufous of edge of wing 

 less extensive than in A. herodias, that of tibiae paler. Tibia and soles of feet

 48-00-50-00; W., 20-00-21-00; B., 5-95-6-50; Tar., r-95-8-25" (Eidgw.). 



193. Ardea wardi Bidgw. Ward's Heron.— This is the Florida rep- 

 ^esentative of A. herodias. It is believed by some ornithologists to be a dis- 

 tinct species, but in my opinion is a peninsular race. The average differences 

 in color between it and A. herodias consist in its whiter lower parts, darker 

 neck, and olive instead of black legs. These diff'erenoes, however, can not 

 always be relied upon, and size is the character by which the two birds can 

 best be distinguished, wardi being the larger, as the following measurements 

 show: L., 52-00; W., 19-75-20-50 ; B., 6-40-6-80 ; Tar., 8-00-8-50.
