294 BIRDS FROM YEZO, JAPAN—STEJNEGER. 
Caprimulgus indicus, with which C. kelaartii seems to be synonymous, 
is sometimes quoted as belonging to the present species, but a compari- 
son of Indian specimens of the former with the table of dimensions 
below will show them to be a much smaller species.

Ceryle lugubris (TEMM.). (176) 
We retain the name given to this bird by Temminck for two reasons, 
first because we regard it as distinct from the Himalayan bird, and, in 
the second place, because Alcedo guttata of Vigors (1831) is preoceu- 
pied by Alcedo guttata of Boddaert (1783) (A. O. U. Code, p. 47, canon 
XXXxIII). Considering the continental bird as distinet, we propose to 
call it Ceryle guttulata, in order not to deviate too much from the name 
by which it has been universally known. 
The chief difference between the Japanese and the continental birds 
consists in the white coloration being much more extensive in the 
former than in the latter. The white bands crossing each feather of 
the upper parts are much broader in C. lugubris, being generally of the 
same width as the dark interspaces, while in the form which we have 
designated as C. guttulata the white cross bands are considerably nar- 
rower. This is not only very striking on the upper side of the folded 
wings, but on closer examination we find that the white cross-bands 
on the inner side of the primaries are more numerous in the Japanese 
form, there being at least one more, this one being about midway be- 
tween the tips and the next band, while in the mainland species, the 
entire tip is unspotted for twice the ordinary distance between the 
white bars. The gray ground color of the back, moreover, is consider- 
ably lighter in C. lugubris. 
C. lugubris is usually stated to be larger than the Himalayan birds, 
but the size of the two forms is practically identical, as will be seen 
from the appended tables. The alleged distinction in the shape of the
