Sebastes scaber. sp, nov. 



D. 12. 1/9. A. 3/5. V. 1/5. P. 18. C. 14. L. lat., circ. 37. 



Length of bead 2^, of pectoral fin 3J, height of body 3f in the 

 total length. Diameter of eye 3' in length of head, rather more 

 than the length of the snout ; interorbital space | a diameter of the 

 eye. Maxilla reaches to below the last third of the orbit. Four 

 strong spines at the pre-opercular angle. A single spine at the 

 antero-superior angle of the eye ; a row of strong spines from the 

 supraorbital ridge to nearly opposite the origin of the dorsal fin ; 

 two opercular spines ; a strong spine on the humez'al bone. 

 A moderate nasal tentacle. Teeth on the jaws and vomer ; none 

 on the palate. The sixth dorsal spine is the longest, about equal 

 to the diameter of the eye ; the thirteenth spine twice as long as 

 that which precedes it ; soft dorsal rather higher than the spinous. 

 Anal much higher than the dorsal, the second spine being very 

 strong, and one-half longer than the longest dorsal spine ; it com- 

 mences beneath the twelfth dorsal spine ; the pectorals reach to 

 opposite the first anal ray. Upper part of the head and interor- 

 bital space scaly. Lateral line armed with sharp curved spines 

 pointing backwards. 



Colors. Roseate with irregular dusky blotches. 



The specimens from which the description has been drawn up 

 were taken by the trawl on Shark Reef during August last ; both 

 are very small, the larger being but 2\ inches in total length.

D. 7/13-14. A. 13-14. Y. 1/5. P. 13/7. C. 18. 



Length of head 3^, of caudal fin 6?, height of body 9^ in the 

 total length. Diameter of eye 6^ in the length of head and 

 Ifo in that of snout. Interorbital space slightly concave, ? of the 

 diameter of the eye. Median ridge faint, interrupted between 

 and for some distance behind the eyes, appearing again on the 

 occiput as a short sharp ridge. Width of head inside preopercular 

 spines f of its length. Maxillary extends to below first third of
