TURIUR ORIENTALIS. 9) 
§ 2856. Ouve—Tangier, from M. Favier, through Mr. Williams, 
1847. 
§ 2857. One——Chemora, Algeria, 18 May, 1857. From 
Mr. W. H. Simpson. 
L§ 2858. Onxe.—Elveden, 1847.] 
L§ 2859. Howr.—Elveden, 1852. (Different nests.) | 
[§ 2860. Zwo.—Norfolk. From Mr. Norgate, 1875. | 
[§ 2861. Oxe.—Cambridge, May, 1886. 
A dwarf egg, measuring ‘86 by 65 inch, from a nest at the back of the 
Colleges, brought to me by a trustworthy man. The largest ege of this 
species in the Collection measures 1:29 by ‘93 inch. |] 
TURTUR ORIENTALIS (Latham). 
[§ 2862. Onve—*“Darasun, Daourie, Juin, 1868.” From 
M. Verreaux, 1871. 
[§ 2863. One.—Siberia. From Dr. Dybowski, through M. 
Verreaux, 1873. 
Both these eggs, the first presumably and the second admittedly received from 
Dr. Dybowski, came to me under the name of Turtur gelastes, now considered 
asynonym of 7’. ortentalis, and they differ so much in size (1:28 by ‘95 inch, and 
1°52 by 1:04 inch) that I was inclined to suppose that one of them might 
belong to another species—perhaps 7. ferrago. But I observe that the Doctor 
has given (Journ. fiir Orn. 1873, p. 98) measurements of six eggs of T. rupicola, 
another synonym of 7. orientalis, which shew great diversity —57°7 to 52 mm. 
by 26 to 24 mm., and the same appears from Dr. Taczanowski’s posthumous 
work (Faun. Orn. Sib. Orient. ii. pp. 754, 755), where eight eges are said to vary 
from 37°6 to 31:2 mm. by from 26 to 25-4 mm. Hence I infer that both may 
be regarded as belonging to the same species, as was originally stated. |
