28 CONTRIBUTIONS TO NORTH AMERICAN ICHTHYOLOGY — II. 



longest rays of the dorsal and anal not reaching to caudal 5 the scales 

 of the body more exposed, and the coloration duller. 



Fin-rays :— D. IX, 10 ; A. Ill, 10. Scales 4-33--10. 



The color of the male specimens in spirits is as follows : — Body olive, 

 with, in some cases, a very faint suggestion of lateral vertical bars ; a 

 large black spot at the angle of the opercles, with pearly-blue mark- 

 ings about its base 5 an obscure bar below eye. 



A number of round, luminous, or pearly-blue spots on the sides of the 

 head, irregular in position but very distinct ; other similar spots — white 

 in spirits, doubtless sky-blue in life — on the membranes of the vertical 

 fins, and in scattered irregular rows along the sides of the body, in 

 some specimens on nearly the whole surface, forming imperfect lines 

 along the sides. Each row of spots is accompanied by two faint blackish 

 streaks. These spots are largest and most regular in position along 

 the middle of the sides, but most definite in outline on the belly and 

 fins. 



The female is duller in color, the flap plain black, with some pale 

 edging, and the body with larger spots, more regular in position but not 

 so well defined. The spots on the fins are also larger and paler. 



Length of largest specimens examined 3^ inches. 



Habitat. — The types were collected at Khiston, N. C, by Mr. J. W. 

 Milner. Upward of thirty specimens were preserved. 



This species seems to be the largest and handsomest of the species of 

 Enneacanthus. Its relationships are most close with the next species; 

 but it is probably the most strongly marked of the genus. The sexual 

 distinctions, evident in all the species, are here carried to the extreme-

fEnneacantlius guttatus, Cope (1869), Journ. Acad. Nat. Sci. Phila. — (not Pomotis gutta- 

 tus Morris (1859), Proc. Acad. Nat. Sci. Phila. 9, which is E. ohesus). 



Enneacanthus ohesus, Jordan (187(3), Man. Vert. 232 (excl. expression " barred", copied 

 from Prof. Baird ; specinaens from Trenton, N. J., supposed to be the male of 

 ohesus) (not Pomotis ohesus Grd.). 



fEnneacantlius gloriosus, Uhler & Lugger (1876), Fishes of Maryland — (not descrip- 

 tion, which seems to be copied from Holbrook) (not Bryttus gloriosus Holbr.). 



No description of this common little species seems ever to have been 

 published. Dr. Morris's notice of his Pomotis guttatus is very superfi- 

 cial, and apparently refers to E. ohesus; the only tangible feature men- 

 tioned being the presence of black bars along the sides, which this 

 species does not have.
