THE CYPRINODONTS. 87 
A variety, punctulata, from Remedios, usually has eleven rays in the 
dorsal, instead of ten as in the Havana types, and the spots are more numer- 
ous and larger. 
Gambusia puncticulata.

Shaped like G@. punctata, but differing in the number of dorsal rays and in 
coloration. The eye seems to be a little larger, the snout a trifle shorter, 
the dorsal shorter and the caudal more regularly convex on the hind margin. 
Instead of regular series of small spots, or vitte, there are small spots of 
black on single scales scattered irregularly about. In cases these spots 
cover more than a single scale; rarely they appear as blotches of black 
large enough to cover the greater portion of the fish (pictura/a), as in 
G. Holbrookii on Plate XI. Fig. 4 and 5. Darker edges to the scales form 
reticulations, not always very distinct. A somewhat indefinite silvery band 
along the flank is present in many cases. The fins may be plain or may be 
thickly sprinkled with small spots, or again, dorsal and caudal may have 
several transverse series of black spots, sometimes fused into bands, varying 
in number from one to five. Belly and lower half of head silvery. A black 
spot, like that on G. Holbrookii, Plate XI. Fig. 9, 12, and 13, is present on 
many individuals, on the lower portion of the flank; and on many if not 
most an oblique spot is to be seen below the eye, a further evidence of close 
relationship to that species. 
Inability to secure @. puncticula/a in the fresh-water creeks where G. punc- 
fala was so abundant, suggests that there may be some difference in habits 
not yet determined. The description is taken from Poey’s types, which, he 
says, were met with “en el foso de las murallas de la Habana.”
