Cope.] ^<J-± [June 7, 



This is probably Agassiz species as above, but the orange on the opercu- 

 lar flap scarcely extends posterior to the black spot, and is easily lost 

 sight of in spirits. 



26. Lepomis purpukescens, Cope. 



Species nova. 



This is an elevated compressed fish, with very small or rudimental 

 opecnlar flap, like the L. notatus, L. ardesiacust and L. nephelus. It is 

 similar to the first, and diidferent from the L. ardesiacus in its large eye, 

 which enters the head scarcely three times, and the interorbital width .75 

 times, but agrees with the latter in its small numerous scales. Thus 

 there are six rows of equal scales above the lateral line, and one small one, 

 and 47 on the lateral line and 13 below it ; (in the L. ardesiacus there are 

 17 below it.) Depth 2.25 to 2.33 in length (exclus. caudal fin.) The 

 spinous rays of this fish are nearly as long as in the L. speciosus. The 

 caudal fin is longer than usual, eqiialling at least, the head. Length of 

 latter, three times in length of body -f head. Six rows scales on the cheek. 

 Length three inches. Mucous cavities small. 



Color in life a pale silvery lilac, darkest in four or five vertical shades 

 across the sides, which disappear in alcohol. Fins unicolor except dark 

 shades on middle of anal, and second dorsal and edge of caudal, with a 

 black spot at lower posterior portion of second dorsal. 



Abundant in a tributary of the Yadkin Eiver in Roane County, North 

 Carolina. 



Lepomis peltastes, Cope. 



A deep stout specicsof small size, distinguished for its large scales, short 

 spines and bright color; mucous caverns small. Eye large, equal muzzle, 

 four times in length of head with long opercidar flap, just equal interorbital 

 width. Head with flap 2.5 times in length; depth 2.1 times in same. Cau- 

 dal fin and peduncle considerably more than one-third the length. Longest 

 dorsal spine equal from end muzzle to middle of pupil ; longest anal 

 reaching base last anal ray. 



Five rows scales on cheek, three large and two small rows above lateral 

 line ; those of middle of sides larger than those on lower part. The pro- 

 file is regularly descending to end of muzzle ; front but little concave. 

 Radii D. X. 11. A. III. 10. Length three inches. 



Color above golden brown, sides and belly golden, top of head blackish. 

 Large black opercular spot, red margined below and beliind. I dorsal fin 

 blackish, II D. blackish at base orange above, anal similar, caudal blackish, 

 yentrals more or less black. The pectoral fins do not quite reach the 

 base of the anal fin. 



This sp3cies is from the Huron River, Michigan, whence it was procured 

 through the kindness of my friend Prof. Alexander Winchell, Ann Arbor, 

 Michigan. Its relationships are to the L. oculatus, Cope, but in that 

 species the eye is smaller, and the tail and peduncle are .33 of the length. 

 In L. anarjalliiius the mucous caverns are much larger.
