the opercular membrane. First dorsal spiue very short, the third the 

 highest, half length of head, the fourth but little shorter ; in the type speci- 

 men the fifth and sixth rapidly shortened, while the seventh, eighth, and 

 ninth are again lengthened, thus forming a decided notch in the course of 

 the spinous dorsal; spines all with pungent tips; dorsal membranes from 

 third to sixth spines very deeply incised, that between third and fourth 

 joining latter on the basal f of its length ; soft dorsal and anal pointed, 

 not falcate, the outline behind angle straight; anal higher than the dor- 

 sal, but shorter than the spinous dorsal; caudal rounded, 1| in the head; 

 pectorals long, reaching beyond the ventraLs, and nearly to front of anal; 

 first anal spine concealed in our single specimen, probably mutilated, the 

 second stronger but much shorter than the third, which is contained 4J in 

 the length of the head. Color of head and body uniform, probably red 

 in life ; a black streak on cheeks, following hinder edge of maxillary: 

 fins all blackish on distal half; basal part of fins scaly. A single speci- 

 men, 16 inches long, from Alhatross Station 3017, in 58 fathoms, near Cape 

 Lobos, on the eastern shore of the Gulf of California. This peculiar spe- 

 cies is characterized by its convex caudal, plain coloration (varied only 

 by a black streak behind maxillary), its comparatively large, smooth 

 scales, the naked maxillary, and the very high spinous dorsal with its 

 deeply incised membranes. Gulf of California; one specimen known.
