NO. 2 AVIFAUNA OF PLEISTOCENE IN FLORIDA VVETMORE 1 5 



meats : Modern Avdca licrodias (seven specimens, including two from 

 Florida) ; metatarsus, transverse breadth of trochleae 16.2-17.3 mm., 

 smallest transverse breadth of shaft 5.9-7.0 muL ; coracoid. trans- 

 verse breadth of head 13.8-15.7 muL Fossils from Seminole Field: 

 metatarsus, transverse l)readth of trochleae 18.4 muL. smallest trans- 

 verse breadth of shaft 8.2 mm. ; coracoid, transverse breadth of head 

 17.3 mm. The material is considered too fragmentary for further 

 consideration at this time. 



CASMERODIUS ALBUS (Linnaeus) 



Egret 

 Ardca alba Linnaeus, .Syst. Nat., ed. 10, vol. i, 1758, p. 144. 



The lower end of the left tibio-tarsus of a young individual is found 

 in the collections made by W. W. Holmes in the Seminole Field. 

 Another was identified in material collected near Venice by J. E. 

 Moore. An ulna of an individual of large size was included in col- 

 lections made near Melbourne l)y C. P. Singleton, in 1928, for the 

 Museum of Comparative Zoology. 



This species has not been recorded previously as a fossil, the only 

 other reference to its i)ossible occurrence in the Pleistocene being that 

 of Shufeldt,' where a fragmentary metatarsus is listed as possibly 

 from this species. 



EGRETTA THULA (Molina) 



Snowy heron 



Ardca thula Molina, Sagg. Stor. Nat. Chili, 1782, p. 235. 



A partly complete metatarsus collected at Bradenton by J. E. Moore 

 is the first record of this species as a fossil. The specimen comes from 

 a small individual. The snowy heron is fairly common in Florida at 

 the present time, and formerly existed there in large numbers. It 

 has not been recorded previously as a fossil. 



HYDRANASSA TRICOLOR (Miiller) 



Loui-siana heron 



Ardca tricolor Miiller, Vollst. Natur.s. Suppl., 1776, p. 11 1. 



The lower end of a right metatarsus comes from the Seminole Field 

 near St. Petersburg. 



The present species is here first recorded as a fossil.
