Closely allied to C. radialis, Q. & G. ; but whilst that species has a notch above the 

 spiniferous angle, the present has its prseopercular margin not interrupted, the long 

 spines of the angle gradually passing into the finer serrature. There are six series of 

 scales between the eye and the angle of the praeoperculum. The maxillary extends 

 nearly to the vertical from the posterior margin of the orbit. Dorsal tin with a notch, 

 the ninth spine being considerably shorter than the tenth. A series of rather small 

 brownish spots above and below the lateral line. 



Three specimens, 4^ inches long, were collected by Messrs. Dow and Salvin on the 

 Pacific coast of Panama. 



8. Sereanus creolus, C. & V. 



I have examined specimens from the Atlantic coasts only ; but Mr. Gill has found it 

 in a collection of fishes from Lower California, the specimens being undistinguishable 

 from those of the West Indies and South America (Proc. Ac. Nat. Sc. Philad. 1862, 

 p. 249).

Caudal fin with the posterior margin convex. The height of the body is rather more 

 than three-fourths of the length of the head, and one-fourth of the total (caudal 

 included). The diameter of the eye is one-fourth of the length of the head. Praoper- 

 culum finely serrated behind, with some coarser teeth at the angle, lower limb entire ; 

 sub- and interoperculum entire. Ventrals three-fourths of the length of pectorals, and 

 reaching two-thirds of the distance between theii- insertion and the commencement of 

 the anal. Brownish, with oUve-coloured spots of larger and smaller size on the body 

 and opercles. All the fins with a narrow white margin. A square black blotch across 

 the back of the tail. 



Descnption. — Body not very elevated ; its greatest height is below the third spine of 

 the dorsal fin, rather more than three-fourths of the length of the head, and one-fourth 

 of the total. The distance between the end of the dorsal and the commencement of 

 the caudal is nearly one-sixth of the length of the base of the dorsal, is contained once 

 and two-thirds in the base of the anal, is one-fourth of the distance between the dorsal 

 fin and the snout, and equals the least depth of the tail. The distance between the 

 eyes is one-half of the diameter of the eye, and covered with very minute scales, which 

 are found also on the prseorbital around the nostrils. The length of the snout is two- 

 thirds of the diameter of the eye. The maxillary bone reaches the vertical from 

 the posterior margin of the eye. The mandibulary is one-half of the length of the
