then goes backward again below it as a narrow band below base of pectoral and along side of body, 
parallel with the upper band, to a little, below middle of caudal fin; a black spot on outer side of 
base of pectoral; bases of upper and lower caudal rays black. 
One specimen, 52 mm. long, secured by Dr. Wood at Honolulu. Type No. 49702, U. S. N. M. 
Family SCOBTbffiNTDJE. 
Scorpsenopsis cacopsis Jenkins, new species. Figs. 13 and 14. 
Head 2.6 in length of body. Depth 3 in length. D. xn, 10; A. in, 5; P. 18. Scales in 50 trans- 
verse series. Specimen described, large and robust, 347 mm. in length. Greatest depth at front of 
dorsal fin; depth here equal to distance from tip of upper jaw to vertical through base of first dorsal 
spine, so that upper profile of head is inclined at angle of about 45°. Lower outline of head descending 
at lesser angle from tip of lower jaw to below pectorals. Mouth on level with median pectoral rays; 
lower jaw projecting beyond upper a distance equal to one-half diameter of eye, most of the teeth in 
front of lower jaw being exposed. Dorsal and ventral outlines of body back of front of dorsal and base 
of pectorals symmetrically converging to base of caudal peduncle, where depth is 3.5 in bead. Eye 
small, 2.5 in snout, on level with middle of caudal peduncle. Snout 2.33 in head, equal to third dorsal 
spine, its upper profile in front of posterior nostril very convex, forming an abrupt hump. A promi- 
nent spine on each side of upper end of this hump between inner rims of nostrils of same side. Inter- 
orbital very concave, least width equal to distance 
from eye to first nostril. Maxilla reaches posterior 
margin of pupil. Below eye a deep cavity on side 
of head, deepest anteriorly. A rectangular depressed 
area on top of head back of eyes. Teeth all villi- 
form, in wide bands in front and on sides of jaws 
and in a V-shaped patch on vomer. 
The spines of the head are distributed as fol- 
lows: Above, three on upper rim of the orbit, a 
fourth back of and within the most posterior of 
these on top of head at anterior angle of the occip- 
ital depression, two approximated spines on occiput 
at posterior angle of occipital depression; laterally, 
a row of three spines back of eve, the last at pos- 
terior end of opercle, one between the second of 
these and the two occipital spines of same side, a 
row of about seven spines from side of snout below 
suborbital cavity to middle of opercle, angle of 
opercle with two dorsally curved spines, the upper 
the larger. Numerous dermal flaps are distributed 
over the head in the following manner: One on pos- 
terior margin of posterior nostril, folding over nos- 
tril like a lid, a large one attached to suborbital and 
overlapping maxilla, several small ones on posterior end of maxilla, three large ones along lower limb 
of preopereular margin, one on each side of preopercle below lower row of spines on side of head; on 
lower jaw two flaps just back of symphysis, three on each side back of these just within ramus of jaw. 
Third dorsal spine longest, about 3 in head; the following three of about same length as third; 
seventh to eleventh gradually shorter; twelfth about one-third longer than the eleventh. Anterior 
soft rays a little longer than the posterior soft rays, equal to fourth spine. Anal short, two-thirds of 
length of soft dorsal; first spine two-thirds of second; second and third spines equal to the fourth 
dorsal spine. Pectoral very large, upper and median rays longest and of equal length, about 2 in head, 
lower rays successively shorter; the lower ten much thickened, angulated near bases, especially the 
short lowermost ones, so as to be bent somewhat inward. Ventrals narrow, 1.66 in head. 
Scales in 50 transverse series, each row almost vertical below the lateral line, oblique above. 
Lateral line straight, extending from above gill cleft to middle of base of caudal fin. Ten scales in 
oblique series from first dorsal spine to lateral line, twenty from lateral line to anus. A few dermal 
flaps irregularly distributed over sides of body, about twelve along lateral line on each side.
