the description of Gamhusia arlingtonia. The largest are about 2J 

 inches in length. 



9. MoUienesia latipinna, Le Sueur. 25312; 25337, I. R. 



10. Heterandria ommata, species nova. 25331 (2). I. R. 



Two female specimens in poor condition, each about an inch in 

 length. 



Head, 3^ in length ; depth, 4. D. 6 ; A. 10. Scales, about 28. Mouth 

 very small, the teeth imperceptible. Eye large. Anal larger than 

 dorsal (not modified in either specimen), inserted immediately below 

 the last rays of the latter. 



Color olivaceous ; fins a little dusky. A large jet black ocellus at 

 upper part of base of caudal and a smaller one above front of anal. A 

 faint dusky shade along sides and one along median line of back. 



This species differs strikingly in coloration from its congener, Heter- 

 andria { = Girardinus) formosa, which is also found in the waters of 

 Florida. 



11. Querimana gyrans, Jordan & Gilbert. 25315. I. R. 



Numerous specimens, somewhat larger than the original types. 



12. Menidia menidia, (L.). 25322. L. J. 



13. Menidia peninsulae, (Goode & Bean). 25318. L. J. 



14. Elassoma evergladei, species nova, 25326 (8), L, J, ; 25334, I. R. 



Head, 3^ ; depth, 3^. D. IV, 9 or 10 ; A. Ill, 5. Scales, 28-13 or 14. 

 Length of largest 1^ inches. 



Body more elongate and less compressed than in Elassoma zonatum ; 

 the head thick, moderately pointed anteriorly, flattish, and moderately 

 wide above. 



Mouth oblique, very small, its outline curved, upper jaw very pro- 

 tractile; lower jaw projecting. Snout very short, not longer than 

 pupil ; preorbital very narrow. Eye, 3 in head. Maxillary of moderate 

 width, barely reaching the vertical from front of eye, its length 4 in 

 head. Teeth in narrow bands, those of the outer series enlarged, close- 

 set, slender, and curved. Apparently a few teeth on the vomer. 

 Cheeks and opercles scaly, the former with 3 or 4 rows of scales. Pre- 

 opercle entire; opercle unarmed, emarginate behind. Gill-membranes 

 broadly connected across the isthmus. Breast with small scales. 

 Scales of body very large, cycloid. No trace of lateral line. Gill- 

 rakers very small, tubercular. Pseudobranchise very small, apparently 

 covered by skin, as in the CenfrarcMdcB. 



Vent normal in position. Dorsal fin low, the first spine short, the 

 others graduated; ventral fins very slender and narrow, their filament- 

 ous tips nearly reaching front of anal; their rays i, 5; inner ray short, 

 so that the number appears on a hasty examination to be i, 4. Pectoral, 

 1| in length of head ; caudal slightly emarginate, 1^ in head.
