 Pcecilichthys lepidus Jordan, Bull. U. S. Nat. Mus. x, p. 16, 1877. 



Several small specimens agreeing closely with Girard's figure and de- 

 scription, excepting that the spinous dorsal is higher and the two dorsals 

 more closely approximated than is represented by him. This species 

 appears to be a typical Pcecilicthys, related to P. variatus. The dusky 

 transverse bars were doubtless blue in life. Girard's original types from 

 Eio Leona, Texas, are still preserved in the museum. 



Genus FU:NDULUS Lacepede. 



Fundulus zebra (Girard) GUnther. 



1859 — Hydrargyra zebra Girard, Proc. Ac. Nat. So. Phila. p. 60. 



Fundulus zebra Gunther, Cat. Fish. Brit. Mus. vi, p. 324, 1867. 



Fundulus zebra Jordan & Copeland, Check List Fishes N. A. p. 141, 1876. 



Numerous specimens, agreeing very well with Girard's account. This 

 species has a much larger anal fin than Hydrargyra similis, with which 

 it is associated in this collection. The specimens are also much shorter 

 and more chubby than H. similis, and different in coloration. The gen- 

 eral hue is dark olive, crossed by numerous irregular, whitish zones, 

 about as wide as the darker interspaces. These bands are quite varia- 

 ble in number and position, some specimens having fully twice as many 

 as others. 



The coloration is very similar to that of Fundulus menona Jordan and 

 Copeland, from Wisconsin and Northern Illinois. The specimens are 

 not in good enough condition for me to be certain as to the number of 

 branchiostegals. I, however, count five, and therefore refer the species 

 to Fundulus rather than to Hydrargyra. 



Genus OAMPOSTOMA Agassiz. 



Campostoma fokmosulum Girard. 



Further specimens of this species indicate that it differs from C. ano- 

 malum in the smaller and more pointed head, and in the much greater 

 compression and elevation of the body in the adult. The scales are also 

 rather smaller than in C. anomalum.
