Symbranchus marmoratus Bloch. T. Pinar del Rio. 
ANGUILLID^E. 
Anguilla chrysypa Rafinesque. San Juan, near its first ford; Paso Real. 
ELOPIU/E. 
Tarpon atlanticus (Cuvier & Valenciennes). M. 
Pinar del Rio, 4 specimens, 20, 119, 182, and 192 mm., from a deep pool beneath the wagon 
bridge, many miles from the sea. They are locally known as “sadina,” and we had been told that 
we should find them in this spot. 
PtECILlIILE. 
The members of this family are everywhere abundant, especially in streams bordering the cave 
region. 
Key to the genera of Cuban Pceciliidx. 
a. Anal fin of male similar to that of female, oviparous; intestinal canal short, little convoluted; teeth little 
movable; dentary bones firmly connected; lower jaw strong and usually projecting beyond 
upper. 
b. Teeth all pointed, in villiform bands. 
c. Air-bladder well developed; no caudal ocellus; gill-openings not restricted above; opercles free from 
shoulder-girdle; dorsal and anal nearly equal; origin of dorsal in advance of anal Fundulus. 
c. Air-bladder wanting; a black ocellus at root of caudal in male; dorsal smaller than anal, its origin behind 
that of anal Rivulus. 
b. Teeth tricuspid in one row, no villiform band of teeth; body short and deep, compressed; dorsal short, of 
10 to 12 rays, first ray slender and rudimentary Cyprinodim- 
aa. Anal fin in male placed well forward and modified into a sword-shaped intromittent organ. 
d. Intestinal canal short, little convoluted; teeth all pointed, in bands; eye normal; jaws not produced; 
dorsal short, of 6 to 10 rays, behind origin of anal; mouth wide, chin low Gambusia. 
dd. Intestinal canal elongate, much convoluted. 
e. Teeth compressed, entire, without lateral cusps. 
/. Anal process in male very long, serrate behind near tip and with finger-like claspers (the prepuce 
being modified into a pair of clasps); dorsal in both sexes behind origin of anal. 
(j. Dentaries and intermaxillaries firmly united; teeth of outer row fixed, a band of minute teeth 
behind them. 
li. Teeth of outer row much expanded at tip, broadly spade-shaped in upper jaw, close-set, their 
margins overlapping; teeth near middle of lower jaw asymmetrically expanded, lateral lobes 
prolonged and ending in a point , Glandickthys. 
hh. Teeth of outer row wide-set, scarcely expanded, spear-shaped, those near middle of lower jaw 
in two irregular series Tuxes, I nov. 
gg. Dentaries and intermaxillaries loosely joined; teeth of outer row movable, inserted on lips, a 
few teeth behind them or none, those of outer row wide-set, scarcely expanded, spear-shaped; 
those of middle of lower jaw in two irregular series Girardinus. 
ff. Anal process comparatively short, a leaf-shaped prepuce attached to the anterior surface covers 
the tip; tip without claspers; dorsal in female in advance of origin of anal, 
i. Tip of anal process in male ending in a simple antrorse hook, no serrae on its posterior surface. . -Pxcilia. 
ee. Teeth all pointed; origin of dorsal behind that of anal Heterandria. 
Fundulus cubensis Eigenmann, new species. * 
l am somewhat in doubt as to the generic position of this species. Its short intestine, double row 
of teeth, unrestricted gill-openings, and position of its dorsal in relation to its anal, and similarity of 
sexes (at least one of the three specimens is a male) seem to indicate that it is a species of Fundulus. 
Type: No. 9667, Ind. Univ. Mus., 29 mm. long; Pinar del Rio. 
Cotvpes: Two specimens, 26J mm. long; Pinar del Rio, at the ford just above wagon bridge. 
Plead 3.6, about equal to depth; D. 11 or 12; A. 10 or i, 10; scales 24. Origin of dorsal very slightly 
nearer tip of snout than base of middle caudal rays and over the eighth scale of lateral line; origin
