Genus NOTIIOXOTUS Ar/assiz. 



8. NOTHONOTUS CAMURUS (Cojie) Jor. 



Professor Cope's types were from the South Fork of tlic Cumberland. 

 We have seen others from White Kiver in Indiana, and from Mahoning 

 liiver and other streams in Ohio. This species is not identical with 

 I^^othonotus maculatus Ag. [Etheostoma maculata Kirt.), as has been sup- 

 posed. 



I^^othonotus maculatus has a pointed instead of rounded snout ; its 

 jaws are equal ; its mouth is larger, the body is more compressed, and 

 its dorsal iin more elevated, the soft rays when depressed reaching to 

 the caudal. 



Specimens in the National I\Iuseum, collected in Mahoning Hiver by 

 Professors Baird and Kirtland, show the following characters : — 



Body moderately elongated, very deep, stronglj- compressed, the 

 depth 4^ iu length. Head 4 in length, the jaws equal, the mouth large. 

 Eye 4} in head. Si)inous dorsal with a long base, larger than soft dor- 

 sal, the spines high, the two fins slightly- connected. Solt dorsal ele- 

 vated, the longest rays when depressed reaching base of caudal, the 

 caudal peduncle very short and deep. Caudal Iin short and rounded. 

 Anal somewhat smaller than second dorsal. Pectorals and ventrals 

 moderate. 



Scales not large, 58 to (50 in the lateral line, which is continuous: 

 cheeks naked : opercles scaly. 



Fin rays: Dorsal XII-13; A. II, 8. 



An elaborate colored drawing of a male fish in life colors, in the 

 Smithsonian Institution, shows the foHowing features of coloration. 

 As we hav^e never seen this species in life, we cannot vouch for tlieir 

 accuracy : — 



Back olive; belly becoming yellowish. Sides and back profusely 

 speckled with carmine-red, the blotches rather less than the size of the 

 eye, not round, nor arranged in rows. 



Dorsal (in with a dull rt'il stripe at base, a brown interval, then a 

 bright red stripe, tinally niargined with \\iiite. Second dorsid dull 

 brown at base, then a broad red stripe; a broad marginal band of 

 white. Caudal similarly tricolor, chielly crimson, witii a broad dusk}' 

 band at base and a wide white band at tlu' tip. Anal chictly crimson, 

 with a terminal band of white. Pectorals ami \-entrals nearly i)lain. 

 Head olivaceous.
