together, the latter followed by a low striate ridge which bears the low 

 occipital ami nuchal spines. No coronal spines. 



Temporal ridge prominent, ending in a spine, and with two blunt 

 spines in front; below these, and about half way to suborbital stay, is 

 another small and blunt spine. Preorbital with two large forward pro- 

 jecting spines in front; suborbital stay with a prominent ridge which 

 bears a small spine below anterior margin of pupil, and two more behind 

 posterior margin (in the young the first of these two is absent). Pre- 

 opercle with four distinct spines, besides some four smaller projections, 

 the largest spine with a small one immediately below. Opercular spines 

 two, large and sharp, the lower the longer. 



Scales small, scarcely ctenoid, those on belly much reduced; breast 

 and region in front of pectorals and ventrals scaled; autedorsal region 

 with 3 or 4 rows of imbedded scales; temporal region with a few im- 

 bedded scales; cheeks with about 4 rows of large scales below the sub- 

 orbital stay; membrane of opercles with a few scales, the opercle itself 

 naked. Scales of body without fleshy flaps. Supraorbital tentacle de- 

 veloped in the young, disappearing in the adult. Dorsal spines not as 

 high as soft rays, the fin deeply notched; first spine 2 in eye, second 

 If, third almost equal to eye, fourth and fifth almost equal, 3 in head, 

 twelfth 3J in head. Longest soft ray of dorsals 2i in head. First anal 

 spine 2^ in second or 2 in eye, second anal spine longer than third and 

 equal to eye; longest soft ray equal to that of dorsal. Pectorals long. 

 1£ in head. Ventral reaching vent, very slightly more than 2 in head, 

 Caudal equal to pectoral. 



Color, dark brown above, probably crimson in life, pale below level 

 of upper half of pectorals. Upper half of head dark but without any 

 distinct spots, the back more or less mottled with dusky. Spinous dor- 

 sal with a dusky band at base and another across its middle; soft dorsal 

 dark at base and with three or four irregular rows of small, obscure 

 brownish spots. Caudal tipped with black, traces of a narrow dark 

 bar across its middle. Pectorals slightly tipped with black, the middle 

 slightly mottled. Ventrals and anals pale or with traces of black on 

 tips of rays. 



Numerous specimens wei*e dredged at a depth of 33 fathoms in Sta- 

 tions 2795 and 2797. 



20. Prionotus quiescens sp. nov. 



Diagnosis. — Related to Prionotus stephanophrys Lockington, but the 

 interorbital area concave; the bones of head much striate and granu- 

 lated, and the caudal differently colored. It also bears some resemblance 

 to the Atlantic species Prionotus stearnsi.
