FISHES OF HAWAIIAN ISLANDS.

A second i^maller specimeu (78 nun. long) was taken at station 4074, off north coast of Maui, ilei)th 

 78 to 85 fathoms. It differs consjiicuously in length of the supraorbital tentacle, which extends 

 beyond the nuchal spines. The j^ectoral rays are in this young specimen all simple. The sjiecies is 

 closeh' related to I'ontiiuts spilinliKX, described from young specimens only. It may well be that ailults 

 of tlie latter have some of the pectoral rays forked, in which case the si)ecies would be referi'cd 

 to the genus Heikvlenus, wdiich is of doul-itful validity. 



Only 2 specimens obtained.

Fig. 247. — Pontinus spiUslius Gilbort, now spocies. Type. 



Eye shorter than snout, but more than twice width of tlH> narrow, deeply concave interorbital space; 

 occiput ri'udered concave by parietal ridges, but without pit or depression; nasal spines small; .-;trong 

 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 ui)i)er, and bearing a single strong spine on a level 

 with the 2 suprascapular spines; opercular spines slentler; 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 backwai'dly directed spines; in the type, but 2 sm dl 

 preocular spines can be detected below uppermost sjiine, l)ut in young specimens 2 more very minute 

 ones an> present, which evidently disappear with age; nmnbered 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 fine each at ba.'^e of the (ireocular, supraocular, occipital, and 

 the 2 posterior preorbital spines; a series also acconijianii's lateral line; maxillary falls short of vertical 

 from middle of orbit; teeth finely villiform, in moderate bands on jaws and vomer, in a long narrow
