JORDAN AND THOMPSON: FISHES OBTAINED IN JAPAN IN 1911. 303 
304. Neobythites sivicola (Jordan & Snyder). (Plate XLII, fig. 2). 
(Watasea sivicola Jordan & Snyder, not of Jordan & Starks). 
Misaki (Coll. Owston). 
The genus Watasea, based on this species, differs from Neobythites only in the 
presence of two weak spines on the pre-opercle, instead of three as in Neobythites 
gilli. Most of the species referred to Neobythites belong to the subgenus Watasea, 
as Radcliffe has lately shown. 
This specimen, No. 6170a, C. M. Cat. Fishes, smaller than the type, is plainly 
identical with it. Body nearly uniformly gray, not banded asin N. fasciatus. 
Dorsal and anal broadly edged with black. This color has faded in the original 
types, both long exposed to sunlight. 
In our young specimen the body is indistinctly covered with irregular faint 
whitish blotches, a row of these being along the dorsal base. The dorsal aside 
from these has no pattern anteriorly, being simply somewhat dusky, gradually 
becoming very black in the last quarter, save for a narrow white margin. This 
is continued on the caudal and anal, the latter being black with a white margin on 
the posterior three-fifths of its length, without other pattern. Specimens identified 
by Jordan & Starks as the young of Watasea sivicola are not the young of this 
species, as may be seen in the accompanying table of measurements. We refer 
these to Radcliffe’s species, N. fasciatus.

Besides the differences in color, the present specimen of Neobythites sivicola 
shows a longer maxillary, lesser number of rays in both dorsal and anal, longer 
pectoral, longer distance from snout to vent, from ventrals to vent, and snout to 
ventrals. In these differences it is in full agreement with the type.
