 is about twice as long as the middle toe and claw. Toes extremely short (for this family). 

 Feathers of head and neck elongate, lance-linear and stiffish, distinct ; the longest forming 

 occipital and jugular tufts. A dorsal train of long decomposed fastigiate feathers, with stiff-

 yellowish ; in which state the bird is '^ Peale's Egret," long held for a distinct species, then 

 long decided to be the young. Length 28.00-31.00; extent about 46.00; wing 12.50-14.50; 

 tail 4.50; bill 4.00; tibiae bare 4.00; tarsus 5.50-6.00; middle toe and claw 3.00. Gulf
