Type, No. 16,728, A. X. S. I'. Panama. Lieutenant Fields. 



Only the above example known. It is apparently not closely 

 related to any of the known species of the subgenus. 



(Named for Balboa, Panama.) 

 Fundulus nottii Agassis. 



Indiana; North Carolina (Wilmington); Georgia (Thomasvil 

 Florida (Leon County and Walaka). 



Fundulus notatus (Rafinesque). 



F. minus Cope, Proc. Acad. Nat. Sri. l'liila., L865, p. 7*. Detroil River,

No. 7,142, A. N. S. P., type of F. aureus Cope. 

 Illinois (Illinois River basin at Marley); Missouri; Arkansas; 

 Indian Territory; Texas (Fort Worth). 



CHRIOPEOPS subgen. nov. 

 Type Lucania goodei .Ionian. 



Form fusiform, elongate. Teeth in jaws in two series, simple, 

 conic, outer row enlarged. Jaws short, obtuse. Dorsal fin inserted 

 slightly before anal origin. Female with an anal sheath. 



Differs from the other subgenera of Fundulus in the dentition, as 

 all have the inner teeth in a fine villiform band, at least in more than 

 one row. It resembles certain species of Zygonectes in the black lateral 

 band, but the anterior position of the dorsal at once distinguishes 

 it. Small fishes, little over an inch in length. 



(Chriope, an old name for Notropis bifrenatus, and "<«</', appearance, 

 to which the type species bears a close superficial resemblance.) 



Fundulus goodei (Jordan). 



Miami and everglades at Miami River (S. N. Rhoads), and Tick 

 Island in Spring Garden Creek of St. John's River basin (Dr. H. A. 

 Pilsbry), Florida. 



( iXVZYGOXECTES subgen. nov. 



Type Haplochilus dovii Gunther. 



Jaws long and spatulate. Gill-rakers rather numerous, 22 to 24, 

 much more so than in many of the subgenera. Dorsal fin inserted 

 entirely behind anal. 



This subgenus differs from Zygonectes in the long anal with 13 to 

 16 rays (compared with 8 to 12 in Zygonectes). The peculiar physi- 

 ognomy, with the extremely depressed head, is also a point of 

 difference.
