In order to determine in each species the normal pattern of musculature
of the jaws, heads of 13 specimens of doves were dissected (all
material is in the Museum of Natural History of The University of
Kansas): White-winged Doves (_Zenaida asiatica_), 40323, 40324, 40328,
40392, 40393; Zenaida Doves (_Z. aurita_), 40399, 40400; Mourning Doves
(_Zenaidura macroura_), 40326, 40394, 40395, 40396, 40397, 40398.
Thirty-seven skulls from the collection of the Museum of Natural
History of The University of Kansas and two skulls from the United
States National Museum were measured. The measurements are on file in
the Library of The University of Kansas in a dissertation deposited
there by me in 1963 in partial fulfillment of requirements for the
degree of Master of Arts in Zoology. Specimens used were: White-winged
Doves, KU 19141, 19142, 19143, 19144, 19145, 19146, 19147, 23138,
23139, 24337, 24339, 24341, 23592, 23593, 24340, 31025, 31276; Mourning
Doves, KU 14018, 14781, 15347, 15533, 15547, 15550, 15662, 15778,
15872, 16466, 17782, 17786, 17788, 17795, 19153, 19242, 20321, 21669,
22394, 22715; Eared Doves (_Zenaidura auriculata_), USNM 227496,
318381. Additionally, the skulls of the Zenaida Doves mentioned above
were measured. All measurements were made with a dial caliper and read
to tenths of a millimeter.
