anterior to a little behind the pectoral fin while the back and belly are 
naked anterior to the spinous dorsal and the vent; on others a few scales 
extend to a little in front of the ventrals, and nearly to the base of 
pectoral, while on the back they are present a short distance in front 
of the spinous dorsal. Between these two extremes are all g-radations. 
Pectoral broad and short, with a bluntly curved posterior outline; 
its tip in some specimens reaches slig'hth^ more than halfway' between 
its upper base and spinous dorsal; in others scarcely halfway. Origin 
of ventrals about under the last fifth of pectoral fin; their length equal 
to snout and half e3^e. Front of spinous dorsal a little nearer snout 
than base of caudal fin (by from diameter of pupil to diameter of 
ej^e), and much nearer anterior end of anal base than base of ventrals. 
Base of second dorsal shorter than that of anal by a distance equal to 
a little more than diameter of eye; it ends a little posterior to anal. 
Second dorsal rays anteriorly a little higher than those of anal, which 
are higher than dorsal spines. Distance between front of first dorsal 
and front of second dorsal a little g-reater than the base of the latter, 
which in turn equals the length of caudal peduncle. Upper lobe of 
caudal equals the head's length. Belly with a thick sharp fleshy fold 
of skin. In two females with eggs this flap is absent. 
Color. — Body probably translucent in life, colorless in spirits, with a 
broad lateral blackish and silver}' band running from base of pectoral to 
base of caudal; its width near pectoral about equal to length of ventrals, 
growing somewhat broader posteriorly and reaching its greatest width 
behind its middle, thence growing narrow on caudal peduncle and broad- 
ening at base of rays, where a V -shaped area constricts it above and below, 
thence continuing on base of caudal rays as a double spot. The band 
black, with more or less silver difiused over it, except at its upper edge. 
Lower jaw dusky; top of head and snout with black markings. A double 
row of dots from first dorsal to occiput, with sometimes other scatter- 
ing dots. Behind first dorsal is a broken band of dots, parting to run 
each side of second dorsal and continuing on caudal peduncle as a 
double row of dots or a difiused band. At shoulder is a dusky spot 
which is sometimes replaced by scattered dots. Opercles and cheeks 
more or less dusky. A dark spot at anterior anal base. Caudal finely 
marked with transverse zigzag dark bands. 
This pretty little fish is common in the surf breaking into tide pools 
about Sagami and Izu, where numerous specimens were taken, the 
largest about 2^ inches in length. Our specimens are from Enoshima, 
Misaki, Hada, Yogashima, and Hashigo, the last presented by Dr. 
Ishikawa. It is known to fishermen as Iso-iwashi or surf sardine, and 
as Namino-huna or flower of the waves. 
The type, numbered 6527, in the Leland Stanford Junior University 
Museum catalogue.
