37. Prochilodus migricans Agassiz. 



Several specimens were collected at Para, and a couple by Dr. Baker 

 and Mr. Mann in the Madeira River. The latter differ in having the stripes, 

 which follow the rows of scales on the back, and the dusky cross bars much 

 more conspicuous. In the Para specimens these markings are more or less 

 obscure, but usually evident.

A specimen taken by Dr. Baker and Mr. Mann in the Rio Madeira 

 about 400 miles from its mouth.

 mouth of the Madeira River.

45. Cheirodon insignis Steindachner. 



A few specimens taken in the little ponds about Ceara Mirim. In the 

 male the lower edge of the caudal peduncle is produced and armed with from 

 7 to 9 spines along its edge. The caudal spot is inconspicuous in the male 

 and the first ray of the anal is longer, making the posterior margin of 

 the fin more concave. There is considerable variation among the females 

 in the concavity of the anal and in the depth.
