13. DICROSSUS Agassiz. 



Dicrossus Agassiz MS., Steindachner, Beitr. Kenntniss Chrom. Amazonenstr., 

 42, 1875 {maculatus) . 

 Type : Dicrossus maculatus Steindachner.

Dicrossus maculatus Steindachner. 



Dicrossus maculatus Steind., 1. c, 42, 1875 (Lago Maximo; Jose Assu, Tonan- 

 tius ; Rio Hyauary ; Rio Tajapuru). E. & E., Proc. U. S. Nat. Mus.,

14. CREXICICHLA Heckel. 



Crenicichla Heckel, Fluss-Fische Brasiliens, 416, 1840 (rnacrophthalnms) . 

 Batrachops Heckel, 1. c. 432 (reticulatus) . 



We have selected for the types of Heckel's names the species 

 evidently considered typical by him. He refers to the figures of 

 macrophthalmus and reticulatus in his generic diagnoses. 



On account of the few species at hand no synopsis of the genus 

 is attempted. The species fall into two groups. Those with 100 

 or more scales in the lateral line (Crenicichla) and those with fewer 

 than 100 scales (Batrachops).
