and lower portions of the prseoperculura, the interoperculum, sub- 

 operculum, the branchiostegal region and the sides and lower or 

 under portion of the mandible papillose or rugose. On the upper 

 portion of the operculum are 3 shallow tube-like elevations par- 

 allel with its upper margin, and which become indistinct after 

 passing over the anterior half. The orbitals are strongly rugosely 

 striate. Teeth strong, canines strongly developed, two pairs in 

 the front of each jaw and the lower fitting in between the upper 

 pair when the jaws are closed. The other teeth in both jaws 

 are graduated from the canines backward, the largest of course 

 being anterior and about one-half the size of the canines. Ori- 

 gin of the P. inferior in the depth of the body and anterior to 

 the tip of the opercular flap which is very small. P. ii, 14, 

 perhaps slightly anterior to the V. which are contained in 

 the former 1^ and have the radii i, 5. Origin of the D. nearly 

 over the same of the V. radii viii, 13, the spines sharp, rather 

 strong, and not thickened, of about equal length, similar to the 

 soft rays which are of nearly uniform length. A. ii, 10 or 11, the 

 first spine shorter than the second and the first soft ray the longest. 

 Upper and lower rays of caudal produced into a projecting point, 

 the lower reaching beyond the upper and the emargination being 

 thus formed is oblique. Rays of the caudal, like those of soft D. 

 and A. , very strong and stout, of the former fin the bases of those 

 which are produced are covered with several rows of small scales, 

 much smaller than the other scales at the base of the same fin. Scales 

 along the bases of the D. and A. smaller than those on the rest of 

 the body and extending somewhat upon the bases of the fins. 

 Scales about 28, the lateral line straight to about the twentieth scale 

 when it falls and runs along the centre of the caudal peduncle. 

 The tubes of the lateral line with several branches on each scale, 

 some of Avhich are in turn themselves branched. Most of the 

 color in life has disappeared, yet the head appears to have been 

 green, with the loreal region and the fronlal region together with 

 the space behind and below the eye forming a band along the 

 margin of the prgeoperculum, across the operculum and over the 

 interoperculum, of a different color. A green spot, in one speci- 

 men, divides the lighter color on the interoperculum and extends 

 for a short distance upon the lower portion of the operculum, this 

 spot being much larger than the same of the largest specimen. A
