200 ON CERTAIN MUSCLES OF BIRDS. 
The Ciconiide possess the ambiens, the semitendinosus, and the 
accessory semitendinosus ; the accessory femoro-caudal is absent. The 
femoro-caudal is very small in Oiconia and absent in Leptoptilus ; and 
the postacetabular portion of the tensor fascie is the same. 
Species examined. 
Ciconia alba. Ciconia maguari. 
nigra. Leptoptilus crumeniferus. 
The Plataleide possess the ambiens, the femoro-caudal, the 
accessory femoro-caudal, the semitendinosus, the accessory semiten- 
dinosus, and the postacetabular portion of the tensor fascise, which is 
small. 
Species examined. 
Platalea leucorodia. Ibis melanocephala. 
ajaja. nippon. 
Ibis rubra. —— spinicollis. 
strictipennis. 
The Phenicopteride possess the ambiens, the accessory femoro- 
caudal, the semitendinosus, the accessory semitendinosus, and the 
postacetabular portion of the tensor fascie; the femoro-caudal is 
absent. 
Species examined. 
Phenicopterus antiquorun. Pheenicopterus ruber. 
The Anseres possess the ambiens, the femoro-caudal, the acces- 
sory femoro-caudal (very large), the semitendinosus, and the post- 
acetabular portion of the tensor fascie; the accessory semitendinosus 
is absent. 
Species examined. 
Anser segetum. Tadorna rutila. 
Bernicla canadensis. Aix galericulata. 
Chloéphaga, sp. Mareca penelope. 
Cygnus nigricollis, Dafila spinicauda.

coscoroba. Metopiana peposaca. 
Dendrocygna autumnalis. Fuligula cristata.

The Columbe possess the femoro-caudal, the semitendinosus, the 
accessory semitendinosus, and the postacetabular portion of the tensor 
fasciee; the accessory femoro-caudal is present in all but Lopholemus 
antareticus. The ambiens may be present or absent; and this feature 
is probably a subfamily character.
