Streak running through the black. The black and white streak is continued 

 along the upi^er border of the caudal fin. A blended yellowish streak runs 

 along the middle of the dorsal and the base of the fin is bluish. The pec- 

 toral is straw-color and the ventral is tinged with red, which grows to a dark 

 red on the first ray and spine. The anal is bluish, with a black border con- 

 tinued along the lower edge of the caudal. 



182. Crenicichla cincta Regan. 



A specimen a foot in entire length was taken in the market at Para. 

 It is much larger than the type, which was 172 mm. in length, and conse- 

 quently differs considerably from the original description. 



The head without the projecting jaw is contained 3^/^ times in the body 

 length; the diameter of the eye 6 times in the head; the snout equals the 

 interorbital width, and is contained 3^/4 times in the head. The maxillary 

 extends to under the pupil, and the depth of the preorbital is equal to three- 

 fifths of the diameter of the eye. The teeth of the front of the mandible are 

 in five series, and the gill-rakers are represented by 8 or 9 low bony tubercles. 

 There are 147 longitudinal series of scales above the lateral line, 18 cross 

 series between the front of the spinous dorsal and the lateral line, and 45 

 between the lateral line and the median line of the belly. The pores of the 

 lateral line number 29 + 15. The length of the last dorsal spine is contained 

 3% times in the head ; the pectoral 2 times ; and the ventral 2^ times. 

 The depth of the caudal peduncle is contained 1^ times in its length from 

 the base of the anal. 



There are 12 well-marked cross bars, counting a short one at the nape 

 and a faint one on the base of the caudal rays. No spots are evident on the 

 soft dorsal ; the caudal shows about five light, broken cross bands, and the 

 basal caudal spot is ringed with light body color. The dark band from the 

 eye to above the pectoral base is faintly indicated along the entire length to 

 the caudal spot. The spine and outer ray of the ventral are dusky. 



183. Crenicichla Johanna Heckel. 



Half a dozen of this well-marked species were collected in the market 

 at Para. The following color description was made from one of them before 

 it was preserved. 



Light metallic green above, shading to darker slaty-blue on side. The 

 back has 11 or 12 dark green cross bars not extending down to middle of 

 side. Shades of light metallic green, similar to that on side, are on opercle 

 and base of pectoral. The dorsal is bluish, with a narrow black border and
