Head 3| to 3f ; depth 4 to 4|. D. IX or X-ll to 13 ; A. I, 8 ; scales 6-48 

 to 50-10 ; pores 15 to 20. Body exceedingly heavy and robust, with ele- 

 vated back and broad, thick head. Anterior profile descending rapidly 

 from front of dorsal, the snout blunt and broadly rounded, but not over- 

 hanging the mouth. Gape large and wide, the mandible little included, 

 the maxillary reaching vertical from middle of orbit, 3 in head. Eye 

 rather small, 4i in head, the interorbital width f its diameter. Preoper- 

 cular margin entire. Cheeks, opercles, nape, and top of head generally 

 scaly ; only the snout, interorbital space, and preorbitals naked. Oper- 

 cular spine little developed. Gill membranes scarcely joined across 

 isthmus. Fins all very small; dorsal spines weak, the median spines 

 highest, half length of head ; soft dorsal scarcely higher than spinous ; 

 anal fin with a single, rather weak spine, the first soft ray articulated 

 and branched. Pectorals and ventrals very small, the latter not reach- 

 ing f distance to vent ; length of pectorals equaling distance from tip of 

 snout to preopercular margin ; caudal broadly rounded. Scales rough, 

 wholly enveloping head and body, except snout and interorbital space ; 

 lateral line incomplete, arched, following the curve of the back; pores 

 absent on 15 to 18 scales. Color in life : Varying shades of grayish and 

 greenish olive, much mottled and speckled with black ; six broad, dark 

 bars across back ; 8 or 10 linear black blotches along lateral line, sepa- 

 rated by silvery interspaces ; a dark streak before, one below, and one 

 behind orbit ; opercle and top of head dusky ; pectorals with several 

 dark bars, ventrals unmarked ; a black blotch at base of each caudal

478. COPELANDELLUS, Jordan & Evermann. 



Copelandellus, JORDAN & EVERMANN, new genus, (quiescens). 



This genus differs from Bolelchihys in having the top of the head closely 

 scaled. One species, found in the lowland swamps and everglades of the 

 south. (Named for Herbert Edson Copeland, 1849-1876, who studied the 

 Darters because he loved them, and who began a monograph of the group 

 in 1874, a work not yet finished, although many have worked upon it.)

Head 3; depth 4. D. IX to XII-9 to 12; A. II, 7; scales 3-48 to 56-10, 

 pores on 21 to 28 scales. Body not greatly elongate, compressed, the back 

 elevated, the back higher and the tail shorter than in Boleichthys eos. 

 Maxillary extending to front of pupil; jaws equal; preopercle a little 

 crenulate above. Eye much longer than snout, 3| in head. Cheeks,
