FISHES OF HAWAIIAN ISLANDS. 
633 
A second smaller specimen (78 mm. long) was taken at station 4074, off north coast of Maui, depth 
78 to 85 fathoms. It differs conspicuously in length of the supraorbital tentacle, which extends 
beyond the nuchal spines. The pectoral rays are in this young specimen all simple. The species is 
closely related to Pontinus spilistius, described from young specimens only. It may well be that adults 
of the latter have some of the pectoral rays forked, in which case the species would be referred 
to the genus Helicolenus, which is of doubtful validity. 
Only 2 specimens obtained. 
Pontinus spilistius, new species. Fig. 247. 
Type, 90 mm. long, from station 4077, off the north coast of Maui, depth 99 to 106 fathoms; type, 
No. 51644, U. S. Nat. Mus. 
Head 47 hundredths of total length to base of caudal; diameter of orbit 12; width at middle of 
interorbital space 4; length of sno.ut 13; length of maxillary 21; depth of body 36; least depth of 
caudal peduncle 11; longest (third) dorsal spine 16; eleventh dorsal spine 8; twelfth dorsal spine 12; 
longest dorsal ray 17; first anal spine 6.5; second anal spine 19; third anal spine 15; longest pectoral 
ray 31; longest ventral ray 24.5. D. xii, 10, last ray divided to base; A. in, 5, last ray divided; P. 17. 
Pores in lateral line 24 or 25; vertical rows of scales above lateral line 55. 
Eye shorter than snout, but more than twice width of the narrow, deeply concave interorbital space; 
occiput rendered concave by parietal ridges, but without pit or depression; nasal spines small; strong 
but low preocular, supraocular, postocular, tympanic, parietal, and nuchal spines, the postocular and 
tympanic displaced laterally, not in line with the others; two ridges below tympanic spine, immediately 
behind eye, the lower longer and stronger than the upper, and bearing a single strong spine on a level 
with the 2 suprascapular spines; opercular spines slender; a sharp ridge from preorbital along suborbitals 
to preopercle, joining the latter at base of the upper longest preopercular spine, which bears a smaller 
spine near its base; subocular ridge with 3 short backwardly directed spines; in the type, but 2 small 
preocular spines can be detected below uppermost spine, but in young specimens 2 more very minute 
ones are present, which evidently disappear with age; numbered from above, the latter form the second 
and fifth spines of the series; on margin of preorbital are 2 minute spinous points anteriorly, and 
a rather strong spine posteriorly; all the cirri are compressed, narrowly lanceolate, with entire edges; 
a pair of cirri present on nostril rim and one each at base of the preocular, supraocular, occipital, and 
the 2 posterior preorbital spines; a series also accompanies lateral line; maxillary falls short of vertical 
from middle of orbit; teeth finely vfiliform, in moderate bands on jaws and vomer, in a long narrow
