310 Tenth Supplement to the A. O. U. Check-List. huis 
S. G. Gmelin used the generic name Larus for the Gulls 
throughout his work (Reise Russl.) and evidently did not intro- 
duce Gavia (Zc. I, 1770, 152) in anomenclatural sense, but merely 
cited Gavia ridibunda phenicopos as the name under which Brisson 
described the bird then under comment. (Cf ALLEN, Auk, 
XVIII, July, t901,—.) Gaza will thus stand as used in the 
Ninth Supplement. 
40a, Rissa tridactyla pollicaris vs. Rissa tridactyla (of. 
SAUNDERS, Cat. Bds. Br. Mus. XXV, 1896, 305). 
The two forms are considered as fairly entitled to recognition. 
(Cf. CuapMan, Bull. Am. Mus. Nat. Hist. XII, 1899, 227.) 
159. Somateria mollissima borealis vs. Somateria mo//is- 
sima (cf. ELLIoT, Wild Fowl, 1898, 294). 
The status of the two forms is retained as in the Check-List. 
(Cf. CHAPMAN, Bull. Am. Mus. Nat. Hist. XII, 1899, 235.) 
258. Symphemia semipalmata inornata vs. Symphemia 
s. Speculifera (cf. ELLtiot, Auk, XVI, 1899, 230). 
The name sfecu/ifera Pucheran is considered as not satisfactorily 
identifiable. 
3d10a, Meleagris gallopavo fera vs. J/eleagris fera (ff. 
ELLIOT, Auk, XVI, July, 1899, 232). 
310%. Meleagris gallopavo osceola vs. Meleagris fera osce- 
ola (cf. ELLIOT, tid. 232). 
510c. Meleagris gallopavo intermedia vs. J/e/eagris inter- 
media (cf. ELLIOT, zbid. 232). 
The Committee fails to recognize the necessity of making any 
change in the names of the subspecies of A7/e/eagris. (Cf. Ninth 
Supplement, Auk, XVI, 1899, p. 108.) 
385. Geococcyx californianus vs. G. mexicanus (GMEL.). 
(Cf SHarPE, Hand List Bds. II, 1900, 174.) 
Phastanus mexicanus GMELIN relates to Geococcyx affinis, 
and not to G. californianus.
