THE FISHES OF NEW JERSEY. 301 



base of soft dorsal, sixth at base of last rays of same, and seventh 

 on caudal peduncle. Alternately on side a series of W-like mark- 

 ings along lateral line, below each saddle more or less even, and 

 one opposite each interspace so that there are usually ten or 

 eleven on side. Top of head variegated. A blackish streak below 

 eye down over cheek, another from front of eye to tip of snout. 

 Upper lip black. Opercle variegated with olivaceous-brown 

 and deep metallic green anteriorly. Rest of head and trunk 

 immaculate. Fins all more or less dusky. Dorsals, caudal and 

 pectoral tinted olivaceous. Soft dorsal and caudal with beau- 

 tiful wavy lines or bars of olive-brown, mostly regular and 

 sharply defined, and edges of fins dusky-slaty. Spinous dorsal 

 mottled with olive-brown. Anal pale slaty, becoming deeper 

 below and marginally. Pectoral with each ray marked at regu- 

 lar inten-als with small bars of pale dusky. Ventral with oliva- 

 ceous-tinted rows, membranes slaty, and inner edge of fin whitish. 

 Male with tips of dorsal spines, pectoral, ventral and anal radii 

 adipose-like or expanded. Iris plumbeous slate-color. An adult 

 female was yellowish straws-color in life, slightly brighter below. 

 Variegations similar to those of male, sometimes pale, and again 

 exceptionally bright and distinct, and also with considerable 

 variation in the same waters. Fins more straw-color, tips 

 slightly adipose-like. Bars on soft dorsal and caudal paler, and 

 markings themselves mostly on radii. Pectoral more ochraceous. 

 Ventral and anal whitish washed with ochraceous. Lips ochra- 

 ceous, sometimes marked or spotted with dusky or brown. Green 

 on opercle very pale, usually absent. Young similar to female, 

 only usually paler and with fewer spots or small specks. Bars on 

 fins confined to radii and without adipose-like developments. 



Abundant in most all of our creeks. They are found most 

 frequently, however, in the smaller streams, usually with sandy 

 bottoms and composed of clear running water, though seldom 

 venturing into rapids. I notice that they also like still shallow 

 pools and may frequently be found in these places resting quietly 

 on their ventral fins, though suddenly darting away a short dis- 

 tance when disturbed, only to remain perfectly motionless until 

 again disturbed. Sometimes as many as a dozen will congregate
