ANNOTATED LIST OP FISHES 



123 



Diagnosis. — Body moderately deep, compressed, depth 3.8 to 4.45 in standard length; head 

 broad, depressed; interorbital broad, 2.15 to 2.5 in head; origin of dorsal a little behind origin of 

 anal, the fin with 8 or 9 rays; anal with 10 or 11 rays; scales 32 to 36 in lateral series, 16 to 18 oblique 

 rows between upper angle of gill opening and origin of dorsal; females in alcohol plain grayish; 

 males with 6 or 7 dark crossbars. 



Description of type, male. — Body moderately deep, compressed; outline straight over head, 

 convex from nape to dorsal; head depressed, fiat above, head 3.8 in standard length; depth 4; snout 

 broad, its length 3.75 in head; eye 3; interorbital 2.15; caudal peduncle 1.55; mouth nearly terminal, 

 the lower lip only slightly in advance of the upper; teeth in the jaws in bands, the outer series 

 enlarged; scales firm, 33 in a lateral series, 18 oblique series between upper angle of gill opening 

 and origin of dorsal, enlarged scales extending forward on snout; dorsal fin with 8 rays, its origin 

 over anterior third of anal, equidistant from middle of eye and tip of caudal; caudal fin round; 

 anal fin somewhat larger than the dorsal, with 10 rays, its origin a little nearer end of caudal than 

 tip of snout ; ventral fins rather small, scarcely reaching vent, inserted equidistant from tip of snout 

 and base of caudal; pectoral fins reaching base of ventrals, 1.5 in head. 



Color. — Grayish-brown above, becoming pale underneath; a prominent dark median stripe on 

 back in advance of dorsal; sides with six dark crossbars and with a faint dark spot above base of 

 pectoral, suggesting a seventh bar; no dark blotch below eye; dorsal fin slightly dusky, with blackish 



7 in. 



i'ia. 4. — Fundulus kompi n. sp. From a paratype (male) 



spots on posterior interradial membranes; caudal fin pale, with small dark spots on basal two- 

 thirds; anal fin pale, with some dusky punctulations and indications of a few dark spots on posterior 

 interradial membranes; ventrals and pectorals colorless. 



Variability. — The smaller specimens (females) appear to be more elongate and less strongly 

 compressed than the adults and they look rather strikingly, in general appearance and color, like 

 female Gambusia. The dorsal and anal fins are lower in females than in males. The color in life 

 of a male (paratype) 40 millimeters in length was olivaceous above, pale blue-green on sides, and 

 cream underneath. The crossbars were green. The fins were colorless, except for reddish spots on 

 the posterior interradial membranes of the dorsal and anal and on nearly the entire caudal. In 

 alcohol the females are plain color, being brownish gray above and pale underneath. A distinct 

 median dark line extends from the nape to the dorsal fin. The fins are all plain unspotted. 



Holotype.—No. 88380, United States National Museum, standard length 39, total length 50 

 millimeters, borrow pit along the Greenwood-Itta Bena Road, June 12, 1925. 



Paratypes. — Seven specimens, from type locality, taken on May 22 and October 2, 1925, and 

 23 specimens from the same pond, collected during August, 1927. 



The relationship of these specimens appears to be with the coastwise swamp species, F. chrysotus, 

 from which they differ (as determined by a comparison of specimens from Greenwood and from 

 Florida (F. chrysotus)) in the more anterior position of the dorsal fin, as compared with the distance 

 from the eye. The fins generally are longer, and the color of both males and females is different.
