 Sci., 1903, 535. 



The specimen mentioned by E. and K. is in bad condition. It 

 was collected in a laguna near the Paraguay. It should probably stand 

 as semifasciata instead of saxatilis-. D. XXII, 11 ; A. Ill, 8 ; scales 



55- 



97. Crenicichla lepidota Heckel. Juan Agenza. 



Ascuncion (416, 277); Tributary of the Paraguay in Chaco, Para- 

 guayo (289) ; Corumba (325) ; lat. 1. 40-42. 



98. Crenicichla brasiliensis adspersa Heckel. Juan Agenza. 

 Corumba (337). This specimen is most nearly like adspersa 



Heckel, from which it differs in having no spots on the body in front. 



99. Geophagus jurupari Heckel. 



Geophagus pappaterra Eigenmann & Kennedy (not Heckel), Proc. 

 Acad. Sci. Phila., 1903, 536. Laguna near Arroyo, Trementina, 

 Corumba (370). 



100. Heterogramma trifasciatnni Eigenmann & Kennedy (Plate XLV, 



Fig. 2). 



Five additional specimens of this species enable us to revise the 

 diagnosis. We take the opportunity to correct a typographical error. 

 The "D. X, 6" should read D. XVI, 6. "Type No. 10066" 

 should read "Type No. 10155." 



The specimens of this species at hand are : 1. The Type No. 10- 

 155, 34 mm. from the Arroyo Chagalalina. 2. Five specimens, 20, 

 24, 25 and 50 mm. long (parts of 315, 318, 324), from Corumba. 



All these specimens agree in color pattern underscored. There is 

 a well-defined black line from the lower margin of the pectoral to the 

 origin of the anal, and continued more or less distinctly to the tip of 

 the first ray ; anal behind this uniformly dusky or alternately light and 

 dusky j a dark streak front eye down and back to the angle of sub- and 

 interopercle ; a dark band from tip of snout to the distinct caudal spot, 

 the band narrowest on head and showing no indications of breaking 

 up on the sides or enlarging into a lateral spot ; base of dorsal more 

 or less duskv ; in one of the specimens there are indications of cross 

 shades on the tail ; first two membranes of the spinous dorsal black 

 in most of the specimens ; ventrals with a large black spot ; caudal 

 uniform, dusky.
