ray of anal ; pectorals reaching veutrals ; ventrals to vent. Male unknown ; 

 female uniform brownish olive ; fins in some specimens with 2 or 3 series 

 of blackish dots. (Goode & Bean.) Arlington River, a tributary of St. 

 John's River ; known from young females only ; most likely a Zyyonectes 

 rather than a Gambusia, though it may possibly prove to be the female of 

 Gtinibunitt affmis. 



Gamliuxiu iirliitt/tunia, GOODE & BEAN, Proc. U. S. Nat. Mus., 1879, 118, Arlington River,

956. FUNDULUS HENSHALLI (Jordan). 



Head 3|; depth 4. B. 5; D. 7 or 8; A. 10 or 11; scales 33-10. Body 

 rather stout, deep, and compressed, the profile nearly straight, the back 

 little elevated, and the caudal peduncle deep; head moderate; mouth 

 rather large ; jaws each with a series of long and rather slender canine-like 

 teeth, behind which is a band of small teeth; the canines larger in the 

 lower jaw; eye large; scales rather large; dorsal fin short and high, 

 inserted slightly behind the anal in the males, exactly opposite it in the 

 females ; caudal large ; anal fin larger and rather lower than dorsal ; 

 veutrals quite small; pectorals moderate. General color olivaceous; 

 sides covered, especially posteriorly, with rather large, irregularly placed 

 orange spots, which also extend on the vertical fins ; dorsal dusky, with 

 a dark bar; head without red; caudal and anal more or less yellow; 

 females obscurely marked ; young with diffuse greenish vertical bars. 

 Length 3 to 4 inches. Rivers and swamps of southern Florida. The 

 largest species of the group called Zygonectes. We cannot always 

 separate young specimens from F. rubrifrons, and perhaps, as Dr. Bean has 

 suggested, the two are not really different. It is barely possible that 

 F. arlingtonius is the young of F. henshalli, but the insertion of the dorsal 

 is apparently different. (Named for Dr. James A. Henshall, its discoverer, 

 well known as a writer on angling.)

957. FUNDULUS RUBR1FRONS (Jordan). 



Head 3i; depth 31; eye large, 3i in head. D. 7 or 8; A. 8 or 9; scales 

 32-11 or 12; B. 5. Body moderately stout, little compressed, not ele- 

 vated, the caudal peduncle deep ; head rather long, broad between the 

 eyes, flat above ; mouth rather large. Teeth small, nearly even, in a 

 narrow band. Scales moderate. Dorsal fin very short and small, placed 

 a little behind the anal or about even with it, its position in the males 

 rather more posterior ; anal short, high in the males ; ventrals very small ; 

 pectorals small. Color: males, dark olivaceous, with a dark, bronze- 

 orange spot on each scale posteriorly, much as in Fundulns catenatus; 

 below, these spots are bright orange; faint, narrow, vertical orange 

 bars along the lower and posterior part of the body ; vertical fins with 

 orange spots ; jaws and space in front of eyes bright orange red; paired 

 fins dusky. Females almost uniform brassy olivaceous, without evident 

 spots or red markings. Length 2| to 3 inches. Streams and swamps of
