22 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 85 



United States National Museum. While closely similar to the humerus 

 of the living blue-winged teal. Qiicrqucdula discors, the fossil is 

 heavier and stronger throughout both in the shaft and in the proximal 

 and distal ends. It thus bears out the characters assigned to it in the 

 original description. 



In the Holmes collection from the Seminole Field there is one right 

 and one left humerus nearly complete, and the fragments of three or 

 more others that corresiX)nd very closely to the type specimen. With 

 them are three broken metacarpals. A portion of a humerus was 

 secured by J. E. Moore near Venice. The proximal half of a right 

 humerus was collected by C. P. Singleton at Melbourne for the Mu- 

 seum of Comparative Zoology. There are also a number of bones 

 from the Itchtucknee River deposits, Columbia County, in the collec- 

 tions of the Florida State Geological Survey. 



Following* are measurements of the four complete humeri at hand. 



Type, Vero, Florida, total length 65.8, transverse diameter through 

 trochleae 9.9, transverse diameter through head 16.1, transverse di- 

 ameter of shaft at center 5.4 mm. 



Two specimens, Seminole Field, total length 65.7-70.2, transverse 

 diameter through trochleae 10.3- 10. 5, transverse diameter through 

 head 15. 3-15.6, transverse diameter of shaft at center 5.1-5.3 mm. 



Three modern Querquedida discors, two males and one female, 

 measure as follows: total length 65.4, 65.9, 61.8, transverse breadth 

 through trochleae 9.7, lO.o, 9.2, transverse breadth through head 13.8, 

 14.0, 13. 1, transverse diameter of shaft at center 4.7, 4.8, 4.6 mm.
