1. Sebastichthys timbrosus, sp. iiov. (:31140, 31141.) 



Head 2| to 2f in leugtb, without caudal ; depth 2f to 21. D. XIII, 

 12; A. Ill, 6. Scales 40 (tubes iu lateral line), the number of cross 

 series about 50 (counted below lateral line). 



Body moderately robust, little compressed, not specially elongate. 

 Mouth moderate, oblique, the nuxxillary extending backward about to 

 iwsterior margin of pupil, its length almost half head. Jaws about 

 equal, the lower with a strong symphyseal knob, fitting into a broad 

 notch in the upper. Premaxillary iu front on level of lower margin of 

 eye. Preorbital narrow, not more than half width of maxillaiy, armed 

 with two retrorse spines. Eye large, 4 iu head, somewhat longer than 

 snout. Nasal spines strong. 



Cranial ridges well developed, sharp, but not high, in form interme- 

 diate between those of pinniger and constcUatus ; as strong as in coti- 

 sfellatus, but lower. Preocular, supraocular, [)ostocular, tympanic, and 

 occipital spines present. Preocular spine very conspicuous ; supraocu- 

 lar ridge low, its spine smaller than postocular or tympanic. Occii)ital 

 ridge about as long as supraocular, about two-thirds eye. Interorbital 

 space much broader than in consteUatiis, its width two-thirds eye; it is 

 concave, with two rather strong ridges diverging backward ; between 

 these posteriorly are two smaller ridges. Suprascapula with two spines. 

 Space between occipital ridges slightly concave. Preopercular spines 

 strong, all of them acute, the second longest and rather slender. 

 Opercular spines well developed. Gill rakers rather long and slender, 

 the longest 24- in eye ; about 24 of them on lower limb of arch. 



Dorsal fin deeply notched ; neither the spines nor the soft rays very 

 high. Longest dorsal spine 2} to 2 J in head ; longest soft ray scarcely 

 shorter. Soft dorsal longer than high. Caudal very slightly emargi- 

 nate, the middle rays 21 in head. Pectoral 3f^ in body, not reaching 

 vent. Ventrals about half head. 



Scales rough, the accessory scales numerous; small scales along 

 bases of fins. Both jaws with some small smoothish scales, those on 

 mandible mostly towards its base. 



Ground color light orange, quite faint or obsolete on parts of the body. 

 Upper parts overlaid with a dusky hue, formed largely of dark points 

 so numerous as to give a dusty appearance. The dark color on the sides 

 forms irregular vermiculations, the center of each scale being pale 

 orange, the edge dusky. Some areas along the back, between the pale 

 blotches, are quite blackish. Jaws and inside of mouth light orange,
