16 FISHES OF TEXAS. 



10. Gambusia patruelis Baird & Girard. 



11. Zygonectes iiotatu.s Eafinesque. 



12. Micropterus salmoides Lac6pMe. 



13. Leponiis liumilis Girard. 



14. Ammocrypta clara Jordan & Meek. (36488.) 

 AbimdaDt. 



15. Ammocrypta vivax Hay. (36487.) 

 Rather common. 



16. Hadi-opterus scierus Swaiu, var. serrula, var. nov. (36481.) 

 Abundant. The Texas specimens of this species differ somewha 



from those examined from Indiana and Arkansas, and may be taken a 

 a distinct variety (ftcrrnla). The scales .are somewhat smaller in vai 

 serrula (lat. 1. GS to 71 in fierriila; 64 to 6Q in most Indiana examples 

 The coloration in serrula is paler, Avith more sharply-defined markings 

 the black blotches on the side being less confluent, and the sides of th 

 III belly without dark clouds. 



In the Texas specimens the breast is naked, while in most Indian 

 exam])les it is more or less scaly. The preopercle is very weakly, bii 

 generally distinctly, sSrrnlate. 



In very old specimens from Indiana these serrations disappear. 



17. Ethsostoma jessi^ Jordan & Brayton. (36482.) 



{Pa;cUichthys jessue Jordan & Braytou=:^P«;ci7ic/(//(//s asjmgaiis Forbes=7'6 

 ciUchthijs sivaini Jordan.) 



Several specimens, all less than 2 inches long. In life these wer 

 dark olivaceous, with cross blotches or bars of dark greenish; bo<| 

 everywhere above and below covered with dark dots. Dorsals am 

 caudal with dark cross streaks, the sj)inous dorsal with an orange-re^ 

 bar across it near the edge. Three dark spots at base of caudal, th 

 median one most distinct. The usual dark markings about eye. N 

 dark humeral spot. Lower fins dusky. 



Scales 5-48-7, their outlines distinct from tbe dark edgings. Breas 

 naked ; na])e scantily scaled or partly naked. Opercles well scaled 

 Cheeks nearly naked ; a few small scales above. Lateral line extend 

 iug about to middle of caudal peduncle. 



These specimens differ a little from typical examples of E. asprigen 

 (=P. J€ssia3 Jordan & Brayton), but these differences seem to b 

 within the range of individual variation in this variable species. 



F. — TRINITY KIVEK, AT DALLAS, TEXAS. 



Tlie Trinity River at Dallas, Tex., is in midsummer a very small streaii 

 of muddy-gray water 7':T'ining with a sluggish current over dirty grave 

 and mud. The conditions are unfavorable to fish-life, and very fe^ 

 species were taken, although tlie locality was very thoroughly exam
