22 FISHES OF TEXAS. 



1. Lepidosteus osseus Linnteus. 



2. Amiiirus nebxilosus catulus Girard. 



Two large specimens of the black Texas variety of the commou Bn 

 head. The original type of Plmelodus catulus Girard has the pectoi 

 spines long, and belongs to A. neMilosus rather than to A. melas. 



3. Moxostonia cougestum Girard. 



4. Cliola vigilax Baird & Girard. 

 Abundant. 



5. Notropis lutrensis Baird & Girard. 



Very abundant in the Eio Blanco ; the males brightly colored. The 

 specimens are more elongate than most of those from Iowa, but they* 

 not seem to differ specifically. 



6. Notropis s-waini Jordan & Gilbert. 



(Alburnus megalops Girard; uot Cyprinus megalops Raf.) 



JSTot rare. 



7. Notropis deliciosus Girard. 



Scarce. Our specimens do not evidently differ from those taken 1 

 us in the Des Moines. 



8. Hybopsis aestivalis luarcouis, var. nov. 



Abundant in the San Marcos, and reaching a length of 3 inch( 

 The specimens of this species from the San Marcos differ from the othe 

 we have in a few respects. The eye is larger than in the types of 

 sterleUis, or than in specimens from the Arkansas Eiver, it being 3^ 

 head in mareonis and about 4 in specimens of (vstivalis of the san 

 size. The caudal peduncle is stouter in mareonis than usual in cestix 

 lisy its least depth being half the greatest depth of the body. 



H. hyostomus Gilbert is another very closely related species. In th 

 the eye is still larger, and the snout shorter and less projecting, 

 all the body is profusely sprinkled with black dots. 



9. Gambusia patruelis Baird & Girard (var. hnmilis. Gthr.). 



{Zij<jonecteH patruelis Girard.) 



Common ; some of the specimens nearly 2 inches long; therefore vei 

 large for this species. 



These evidently represent the Zygonectes brachypterns of Cope, ar 

 apparently the Gamhusia gracilis of Girard {=hnmili.s Gthr.). From tl 

 ordinary imirnelis they do not evidently .differ except in color, tl 

 black suborbital spot being very faint or occasionally even obsolete, ai 

 the fins nearly plain. It is not likely that this form will be found sr 

 ficiently different from the ordinary patruelis to be worthy of speci 

 notice. 



10. Anguilla anguilla rostrata Le Sneur. 



A large Eel taken in the San Marcos Spring 



11. Micropterus salmoides Lac6p6de.
