the scale. Between the occipital ridges the scales, in five series, are 
mostly little modified, but become reduced in size near the median 
occipital scute; this scute bears a strong median and a weak lateral 
keel; there is no second scute between this one and the dorsal fin; a 
scute near the origin of the lateral line bears a strong spinous crest, 
with a weaker ventral carina. The scales in the median of the five 
series between the occipital and the postrostral ridge series are 
markedly enlarged, some bearing as many as 13 divergent carinae. 
As in notatus and triocellatus, as distinguished from sexradiatus, the 
fossa within the anterolateral margin of the snout is largely covered 
by prickles, leaving only a narrow groove along the outer side of 
those series of scales which bound on each side the median rostral 
ridge scales; the scales of these series are similar to those of preced- 
ing species, bearing an outer subparallel and an inner oblique group 
of carinae; posteriorly, small scales are inserted between the main 
series and the median rostral series. The underside of the head bears 
no scales. 
The first dorsal spine is short and strong; the second is long, 
and it terminates in a long filament; the third ray is as long as 
the snout plus the orbit. The base of the first dorsal is contained 
1.3 times in the interval between the dorsals, and 1.5 times in the 
postorbital length of the head; the second dorsal fin is rather low 
anteriorly. The origin of the anal fin hes below the anterior por- 
tion of the interdorsal space. The pectoral is contained twice in 
the head; the second ventral ray reaches the anal origin. 
As a wide sexual dimorphism was demonstrated in C. maculatus, 
velifer, and .sewradiatus as regards the length of the fin-rays, a 
comparison of these characters is added, based upon the type, a 
male, and the paratype, a smaller female. Although the difference 
is less striking, it is probable that in this species, too, the fin-rays 
are longer in the male than in the female. —

The ground color is light, about as in C. triocellatus. The dusky 
shade-of the belly extends forward to, or nearly to, the isthmus, and 
on the sides to above the ventrals, thus distinguishing this species 
from notatus and sexradiatus. The markings of the two specimens 
are not strong. The large spot above and behind the pectoral in-
