Snowy heron, Latham. 
Sp. Ch.— Occiput much crested. Dorsal plumes reaching to the end of the tail. Colors pure white. Bill black ; the 
base yellow. Legs black. Length, 24 ; wing, 10.20 ; tarsus, 3.80 ; bill above, 3.15. 
Haft.— Coast of Middle and Gulf States, and across to California. 
Bill compressed ; culmen slightly concave in the hasal two-thirds ; terminally more convex 
than the gonys. Middle toe, three-fourths the tarsus. Tibia hare for nearly one-half. Occiput 
with a full crest of loosely fibred feathers as long as the bill ; the feathers on the lower part of 
the throat somewhat similar. The middle of the back with a series of plumes, with the fibrillae 
distant and lengthened ; the plumes recurved at tip, where the fibrillae of opposite sides are 
horizontal, but approximated together in a -vertical plane. They reach nearly to the tip of the 
tail, sometimes beyond it. 
Bill black, yellow at the base, including the loral region and around the eye, as also a larger 
basal portion of the lower mandible. Leg black ; the lower part of the tarsus behind and the 
toes yellow. Color of plumage throughout pure white. 
A specimen from California, 9469, has the occipital crest much elongated, considerably 
longer than the bill ; the other plumes also more developed. 
This species differs from the Garzetta egretta, Bon., of the Old World, in having the bill shorter 
than tbe tarsus, instead of equal. The crest in egretta is much smaller and less developed. 
Most authors quote Jacquin for the name candidissima of this species. A reference to this 
work shows, however, that he used the word nivea, already pre-occupied for the Ardea garzetta
