10. Notropis venustus Girard. 



Very abundant. Males with the fins bright orange-yellow in life; the 

 tips milky. Back steel-blue. 



11. Notropis deliciosus Girard. 



Identical with specimens taken in the Eio Comal, but a little paler 

 than the latter. 



12. Notropis texanus Girard. 



A single specimen, identical with those from the Trinity already men- 

 tioned. 



13. Gambusia patruelis Baird &, Girard, var. 



Suborbital bar scarcely visible ; otherwise essentially as in the Eastern 

 form {patruelis). 



14. Zygouectes notatus Rafinesque. 



15. Micropterus salmoides La(<Spede. 



16. Lepomis cyanellus Rafiuesque. 



17. Lepomis megalotis Rafinesque. 



Coloration peculiar; young, in life, light green, with light bronze 

 streaks along the rows of scales, alternating with grayish-blue. Oper- 

 cular flap with broad pale edging. 



18. Chaenobryttus gulosus Cuv. & Val. 

 In Leon Eiver. (36546.) 



19. Hadropterus scierus Swaiu (serrula). 

 Common in the river. 



20. Etheostoma lepidum Baird & Girard. (36547.) 

 Abundant in the springs and their outlets. 



General form and appearance of U. cceruleum. Olivaceous above ; 

 male with broad cross-bars, broader and less oblique than in U. cceru- 

 leunij of ablui.sli-greencolor, and separated by bright orange interspaces. 

 First dorsal bluish on edge, then pale, then a stripe of bright orange, 

 then dusky and yellowish at base. Soft dorsal si^eckled, with a difi'use 

 median band of orange. Breastand throat orange; anal pale; ventrals 

 bhiish; caudal speckled, with some yellowish. 



This species is extremely close to U. coeruleum, with which, through 

 var. speciahilc, it may prove to be connected by intermediate forms. In 

 details of form there is no api)reciable difference between the two. In 

 E. lepidum., the head is, however, entirely scaleless, and the bars on the 

 sides are greener in color, broader and less oblique. The nape is usu- 

 ally thinly scaled, as is often the case in E. codruleum. We count P. 

 IX, 12 ; A. II, 6. Scales, 5-48-8.
