this species is identical also Avitli C. hovimis (Baird & Girard, Proc. 

 Acad. Nat. Sci. Phil. 1853, 389), and with C. cximius (Grd. Proc. Acad. 

 Nat. Sci., Phil. 1859, 158). But as hovimis is described as having head 

 3 in length, eye 4 in head, ventrals under anterior margin of dorsal, tin 

 raj'S fewer in number, D. 9, A. 8, aad with somewhat different colora- 

 tion, and G. eximius with head about 3J in length, eye 4 in head, D. 12, 

 A. 12, and different coloration, it is not advisable to include them, for the 

 present, in the synonomy of variegatus. 



21. Fundulus similis (Gkard) Jor. P. G. (30812 Pens. ; 30920 Galv.) 



Body very long and slender, the outlines scarcely arched; adults 

 much deeper than young; head narrow, very long, and regularly nar- 

 rowed forwards; preorbital exceedingly wide, as wide as eye, 4J to 5 in 

 length of head; eye small, 5 to 5 J in head, IJ to li| in interorbital width; 

 posterior margin of orbit slightly behind middle of head ; eye If in 

 length of mandible ; mouth small, maxillary not nearly reaching vertical 

 from anterior nostril; teeth very small, in broad villiform bands, the 

 outer series not at all enlarged ; interorbital width 3.^ in head. 



Dorsal fin long and rather low, the height less than length of base in 

 adult males, 1^ in length of base in females ; in males the last rays are 

 but little higher than some of those preceding, in females the last are 

 the lowest; longest ray (in <?) 2^ in head; origin of dorsal nudway 

 between middle of eye and tip of caudal. Origin of anal under third 

 dorsal ray, the fin much higher than dorsal, the longest ray 1^ in head ; 

 the rays regularly increase in length to the sixth ; the seventh, eighth, and 

 ninth then rapidly shortened, the last again somewhat longer ; thus the 

 anterior outline of the fin is convex, and the posterior deeply emarginyte 

 or falcate, or in females nearly vertically truncate ; posterior margins of 

 oviduct adnate along either side of third anal ray, forming a pouch at 

 base of first and second rays, covering one-fourth length of first ray. 

 Pectorals reaching origin of ventrals. If to 1| length of head ; ventrals 

 not reaching vent, 2 J in head; their base midway between pectorals and 

 origin of anal; caudal subtruncate, 1| in head. 



Scales large, in regular series ; 33 oblique series from opercle to base 

 of tail ; 11 in an oblique series upwards from vent to mid«lle of back ; 

 humeral scales not enlarged. 



Head 3^ in length ; depth 3| to 4f ; D. 11 to 13. 



A. 10 ; scales 33—11. 



Color: ^, olivaceous, bronze below; lower parts of head strongly 

 orange ; sides with 10 to 15 narrow dark bars, one-third to two-thirds as 

 wide as the interspaces, and not very dark, although distinct; a large, 

 diffuse, dark humeral blotch, extending froai above opercle to about base 

 of pectoral; each scale with a distinct > -shaped intermarginal series of 

 dots, forming conspicuous reticulations. Dorsal dusky Avith black 

 specks, mostly black at base ; a small ocellated black spot behind, dis- 

 appearing in adults ; caudal faintly clouded with dusky, especially about 

 the middle ; ventrals pale, somewhat soiled.
