230 MEMOIRS OF THE CARNEGIE MUSEUM. 
Tip of snout level with center of eye; maxillary ending below nostril and before 
eye; mouth but slightly oblique; male with tubercular prominences close together 
on front of snout; a number of horny buds ranged along upper anterior rim of orbit, 
and numerous others over dorsal surface of head in full breeding male; no barbels 
present; gill-rakers (in cotypes of same size) 3+10; pharyngeal teeth smooth, some 
hooked, others simple, sickle-shaped, grinding surface narrow, in some an indication 
of transverse striation. 
Dorsal inserted midway between tip of snout and base of caudal, its first 
branched ray not reaching base of last, when supine; second ray flexible and pointed 
at tip, not spine-like, equal to length of succeeding ray; last ray more than three- 
fourths the length of the second; anal similar, its last ray two-thirds the length of 
third, its margin straight, not faleate nor emarginate; its insertion under third 
branched ray of dorsal, tips of last dorsal and anal rays opposite, when supine; 
pectorals not reaching bases of ventrals; latter barely reaching anal insertion; caudal 
longer than head. Lateral line lacking, scales in corresponding series in no way 
modified. Dorsal line of body very dark between occiput and insertion of dorsal; 
lateral blue-black band rather faint, pointed acutely at both ends, one-fourth as 
wide as pupil, beginning under fifth or sixth dorsal ray and continued to within four 
scales of base of caudal; shoulder-spot behind angle of gill-opening indefinite, though 
present, succeeded by a similar silvery area and another indefinite blotch, the whole 
larger than eye; dorsal dusky, with two rows of white spots on rays, the proximal 
row half-way up fin; no large spot present; anal similar, but much less distinctly 
colored, narrowly edged with black; ventrals dusky (breeding male); pectorals and 
caudal clear; ventral surface of belly pigmented. 
The females of this species seem to be slenderer, depth 2.5 in length; without 
dark ventrals; anal with black margin; belly pigmented and with a fainter lateral 
stripe and color-pattern on fins less plainly shown. 
A male specimen from Nagoya, resembling this species, has thirteen dorsal 
rays and fourteen rays in the anal, with a lesser depth of body. Having but the 
single specimen, we hesitate to regard it as a distinct species. The fins are plain 
dusky, the lateral stripe as in the other specimens; the lateral line entirely lacking. 
Two from Lake Biwa have a like number of fin-rays, and have a black spot ante- 
riorly on the dorsal. Asthe normal number of anal raysin Rhodeus kurumeus is 
but twelve, it is probable that these specimens represent at least one other species. 
59. Tanakia oryze (Jordan & Seale) gen. nov. 
An examination of the type of Rhodeus oryze@, at present in the collection 
of Stanford University, shows the lateral line to be apparently lacking posteriorly,
