ART. XXVI -NOTES ON A COLLECTION OF FISHES FROM THE 

 RIO GRANDE, AT BROWNSVILLE, TEXAS-CONTINUED.* 



By D. S. Jordan, M. D. 



A portion of the collectiou of fishes from the Eio Graude noticed on 

 pp. 395-406 of this Bulletin were accidentally separated from the rest, 

 and escaped attention until the preceding pages had gone to press. In 

 this lot are the following additional species : — 



Genns XENOTIS Jordan. 



Xenotis bPcEVICeps (Baird & Girard) Jordan. 



1853 — Pomotis irericeps B. & G., Proc. Ac. Nat. Sc. Phila. p. 390. 



Pomotis hreviceps B. &. G., Marcy's Expl. Eed Eiver, Zool. p. 246, pi. 13, 1853. 



Pomotis Ireviceps Girard, U. S. Pac. E. E. Expl. Fishes, p. 28, 1858. 



Ichtlielis Ireviceps Jordan & Copeland, Check List Fishes N. A. p. 138, 1876. 



Xenotis hreviceps Jordan, Bull. U. S. Nat. Mus. x, p. 36, 1877. 

 1854 — Pomotis nefasius B. & G., Proc. Ac. Nat. Sc. Phila. p. 24 (not Pomotis aqiiilensis 



B. & G.). 

 1858 — Pomotis popei Girard, Pac. E. E. Expl. Fishes, p. 26. 



Xenotis popii Jordan, Bull. U. S. Nat. Mus. s, p. 36, 1877. 



A single lialf-grown specimen, agreeing well with the descriptions of 

 nefastus and^oj?ii, but not distinguishable by me from X. hreviceps, which 

 species seems to be generally distributed in Texas. The specimens in 

 the iJJational Museum labelled (by Dr. Girard?) Pomotis aquilensis in- 

 clude two species, the one a Xenotis, and probably identical with Xeno- 

 tis hreviceps, the other a Lepioponms,\)rohsbh\j identical with Lepiopomus 

 pallidus. The original aquilensis belonged to the latter type, so the 

 name may be provisionally treated as a probable synonym of pallidus. 

 The other specimens are probably those originally called nefastus, and 

 seem to be referable to Xenotis hreviceps. X. hreviceps is closely related 

 to X.fallax, but appears to be distinct. 



Genus POECILIOHTHYS Agassiz. 



{Astalichthys Le Vaillant ; Oligoceplialus Girard.) 



PcECiLicnTHYS LEPIDUS (Baird & Girard) Girard. 



l^bZ—Boleosoma Jepida B. & G., Proc. Ac. Nat. Sc. Phila. p. 388. 



Pocciliclithiis lepidus Girard, Mex. Bound. Surv. Ich. p. 11, pi. 8, f. 14-17, 1859.
