Peritoneum white. Here described from a specimen 9 inches in length 

 from Tokyo. 



This handsome species is known to us by several specimens from 

 Aomori, Miyako, and Tokyo. It is rather rare, livino- in water of 

 some depth, its nearest American ally being- S{^)aRt(>de^ , prong er . 



(Named for Mr. Joyner, who collected for the British Museum in

Head 2f in length; depth 2i. Dorsal XHI, 13; anal HI, 7. Pores of 

 lateral line 32. Eye 2f in head; maxillar}^ 2^. Interorbital width If. 



Lower jaw slightly projecting. Symphyseal knob prominent. 

 Teeth fine and sharp, in very narrow bands, developed in a knob at 

 tip of mandible which fits in a notch in premaxillaries. Maxillary 

 reaching to below middle of e3'e. Snout two-thirds eye, interor- 

 bital rather wide, three-fifths the diameter of eye, deeply concave, the 

 supraorbital edges not abruptly raised as ridges; along its middle are 

 a pair of weak ridges with a shallow rather wide channel between 

 them. Cranial ridges scarcely developed except parietal ridges, which 

 are very high and sharp. Cranial spines moderate in size and sharp. 

 Preocular, supraocular, postocular, tympanic, parietj>l, and nuchal 

 spines present. Preorbital with an anterior broad rounded lobe and 

 2 spines. Preopercle spines sharp and the 2 upper ones rather slender; 

 the lowest are directed downward, the next 2 downward and backward, 

 and the 2 uppermost backward. Two opercular spines, the upper one 

 long, sharp, and slender. Gill rakers long and slender, one-third eye, 

 22 on anterior limb of arch. 



Pectoral rather slender, reaching to above base of third anal spine; 

 number of rays 19, the lower 10 simple and not much thickened. Ven- 

 trals covering A^ent, not reaching anal. Fifth dorsal spine equal to 

 length of soft dorsal rays, which are equal or very slightly exceed 

 diameter of orbit. Next to the last dorsal spine li in head; last 3^. 

 Second anal spine stronger, slightly shorter and more curved than 

 third, its length 2| in head; first spine half as long. Caudal slightly 

 concave. 



Scales strongly ctenoid. Mandible, preorbital, and maxillary with 

 tine scales. Fine scales cover soft fin rays nearly to their tips. Peri- 

 toneum jet black, inside of gill covers dusky. 



« The specimens from the Aleutian Islands in Pallas' s collection (No. 8145, Mus. 

 Berlin) referred by Dr. Hilgendorf to S. matsnharn', belong to Scbastodes (tJciitimms 

 Jordan and Gilbert, an allied species with smaller scales and lower spines.
