NO. 20 PLIOCENE BIRD REMAINS— WETMOKK II 



condylar fossa broadly open, leading anteriorly into a broad rotular 

 groove. Bone brownish white, varying to slate or dull white at the 

 extremities and along shaft ; strongly fossilized. 



Measurements. — Total length 66.9 mm, transverse breadth through 

 head 15.4 mm, transverse breadth of shaft at center 6.7 mm. trans- 

 verse breadth through condyles 16.5 mm. 



Remarks. — The type femur is about the size of the corresjjonding 

 bone of the emperor goose, Philacte canagico, which may be taken as 

 some criterion of the relative size of the new species. In the arrange- 

 ment of the various tubercles on the shaft and in other particulars 

 it agrees with CIicii and differs from Branfa, being closely similar. 

 except as indicated above, to the modern snow geese. Tt represents 

 an interesting addition to our steadily increasing list of fossil birds. 



QUERQUEDULA sp. 



In material collected Ijy Elmer Cook there is the distal end of a 

 humerus (U.S.N.M. no. 12829) obtained February 11. 1931. in Can- 

 yon 3. i^ miles south of the main quarry and 350 feet above the river, 

 that represents a teal of this genus, being equal in size to males of 

 Querquedula discors and Q. cyonoptcra. 



The upper section of a coracoid (U.S.N.M. no. 12833) secured 

 in 1932, about 3 miles south of the Plcsippus quarry and al)0ut 200 

 feet lower, agrees also in form and size with this genus, having the 

 head slightly heavier than in Nettion, which is about equal in size. 



Anatidae 



• 



In material associated with the cormorant bones from a locality 

 3 miles south of the Plesippus quarry there is the distal end of a 

 metatarsus and the head of a humerus (U.S.N.M. no. 12241) belong- 

 ing to this family that cannot be certainly identified. They represent 

 birds about the size of the blue-winged teal ; the two may possil^ly 

 come from one species, though this is not certain. They cannot be 

 allocated to any genus on the basis of present information. 



The distal end of a tibio-tarsus (U.S.N.M. no. 12831) obtained by 

 Cook about 3 miles south of the main quarry comes from another 

 species of duck about the size of a shoveller but having the inter- 

 condylar sulcus broader than in that species. It is so worn that it 

 cannot be certainly identified.
