ON THE ZOOLOGICAL POSITION OF TEXAS. 33 



Aponiotis cyanellus Eaf. ; Calliurus formosus Girard; Bryttus minco- 

 pas Cope. From Dallas and Fort Worth, from the Trinity Elver. I 

 have also noted this species from Minnesota to Virginia, in the Mis- 

 sissippi Valley. 



Apomotis sp. This species agrees nearly with Girard's description 

 of Bryttus humilis Girard, bnt Professor Jordan informs me that it is not 

 that fish. The form is rather elongate and compressed, and the head is 

 elongat<3-conic, with a large eye, one-fourth its length. The palatine 

 teeth are present, and the maxillary bone extends to the line of the 

 anterior margin of the pupil. Kadii : D. X-10 ; A. IIl-S. The ventral 

 fins originate a little in advance of the line of the first dorsal. Every 

 scale has a yellow centre, and the larger specimens are dusted over with 

 black dots. From the Llano Eiver. 



Leponiis speciosus Gird. (?) ; Pomotis Gird. This is my Lepomis longis- 

 pinis, a species which ranges north as far as Nebraska and Indiana. 

 Girard's description apiJlies well to it, but his figure (TJ. S. Mex. Bound. 

 Surv., pi. iv, figs. 5-8) represents it very badly, so much so as to lead 

 me to question the applicability of Girard's name. Numerous speci- 

 mens from the Llano Eiver. Eadial formula: D. X-11; A. III-ll. 

 Scales 7-40-14. 



Lepomis anagalUnus Cope var. I took a sunfish in the Trinity Eiver 

 at Fort Worth which apparently forms a geographical race of this 

 species. The only peculiarities which I observe are the absence of a 

 soft ray from the dorsal fin, and addition of one to the anal, and the 

 shade of the color. The spots and shades which are red in the northern 

 form are yellow here; this color is especially to be noted in the anal and 

 ventral fins. There are no black spots on the dorsal fins. Eadii : D. IX- 

 10; A. III-9. Scales 5-3G-11. In three specimens out of seven there 

 are only nine dorsal spines. 



Xenotis megalotis Eaf.; Lepomis Coj)e (Journal Academy Nat. Sci. 

 Phila., 1866, 220) ; Pomotis nitidus Kirtland. The most abundant fresh- 

 water fish in Texas, including two varieties; the one jjossessing a black 

 spot on the second dorsal, the other lacking it. I have the former from 

 the Trinity at Fort Worth, the Helotes Creek, and the Upper Medina ; 

 and the unspotted form from the Trinity at Dallas and Fort Worth, and 

 Johnson's Fork of the Llano, in Kimble County. 



HAPLOMI. 



Fundulus diaphanus Les. Abundant with Gampostoma in a pool in. 



the otherwise dry bed of Comanche Creek, Mason County.
