 Skiffia bilineata, Meek, Publ. Columbian Mus., Zool. v. 190i, p. 144, fig. 45 -. 



Hah. Mexico, Rio Lerma System : 



Leon ill Guanajuato ^ ; Huingo 2. 



This species agrees with G. mulUpunctata in the number of scales and fin-rays, but 

 has the dorsal fin placed further back, whilst the markings are quite different. 



5. Groodea wliitii. 



Goodea ivhitei, Meek, Publ. Columbian Mus., Zool. v. 1904, p. 137, fig. 40'. 



Depth of body .3 to 4 in the length, length of head 4. >Snout as long as or shorter than eye, the diameter of 

 which is 3 to 3^ in the length of head ; interorbital width equal to the distance from posterior margin 

 of pupil to free edge of operculum. 48 to 55 scales in a longitudinal series. Dorsal 14-17; origin 

 equidistant from tip of snout and posterior end of caudal fin. Anal 12-14 ; origin posterior to that of 

 the dorsal. Pectoral about |- the length of head. Caudal truncate, the upper angle sometimes a little 

 produced. Brownish above, yellowish below ; each scale of the upper part of the body with a dark spot : 

 usually a blackish lateral stripe ; vertical fins dusky, more or less distinctly spotted, sometimes with a 

 pale edge and dark intramarginal stripe. 



Hah. Mexico, upper tributaries of the Rio Balsas : 

 Yautepec^; Cuautla ^. 



Here described from several specimens, measuring up to 90 mm. in total length, 

 from Yaiitepec and Cuautla {Meek).

 Skiffia varieffuta, Meek, t. e. p. 143, fig. 44". 



Depth of body 2= to 3j in the length, length of head 4. Snout shorter than eye, the diameter of whicli is ',i 

 in the length of head ; interorbital width equal to or a little more than the postorbital part of head. 

 Ij4 to oS scales in a longitudinal series. Dorsal 12-15 ; origin equidistant from snout and base of caudal 

 ( o ) 'Ji' nearer the latter ( $ ). Anal 13-15 ; origin posterior to that of the dorsal. Pectoral q-i the 

 length of head. Caudal truncate. Males dark brownish ; females olivaceous, with irregular darker 

 spots ; sometimes an indistinct dark lateral stripe and a spot or bar at the base of caudal ; fins plain. 



Hah. Mexico, Rio Lerma Sj^stem and Valley of Mexico : 



Celaya ^ ; Lake Pat/cuaro ^ ; Lake Zirahuen " ; Lake Chalco ^. 



Here described from a number of specimens, measuring up to 65 ram. in total leno-th, 

 from Lakes Patzcuaro and Zirahuen {Meek). I am unable to detect any differences 

 between the examples from these two lakes, sent as S. lermce and S. variegata respectively.

Skiffia ritultipunctata, Meek, Publ. Columbian Mus., Zool. v. 1904, p. 141 ". 



Depth of body 2lj to 21 in the length, length of head 4. Snout shorter than eye, the diameter of which is 3
