among the floating plants with half their bodies 
out of the water, and Mr. Richard Dorn has 
observed specimens in his aquarium adhering to 
the sides of the jar or to the glass cover, out of 
water, for a long time. The species is supposed 
to be air bladder, but Jordan and 
Evermann did not find this true in the case of 
some Fivulus from Cuba.

They are egg layers, and the parents or eggs 
should be removed after spawning occurs. The 
young may be expected to hatch in two weeks’ 
time or slightly sooner. 
Rivulus have lived for three years at the 
Aquarium, and showed a preference for live 
food, meat, fish and shellfish. though on oc- 
casion they would accept dried shrimp and 
other prepared foods. 
JANUARIUS 
A little, grayish-yellow fish with black spots, 
Januarius has been introduced into the United 
States and also into Europe, from the West In- 
dies and Central and South America, where it in- 
habits streams. The sexes are similarly marked, 
and it thrives under conditions suitable for our

native fishes. Its breeding habits and food are 
about the same as those of the rainbow fish. 
Scientifically it was long known as Girardinus 
reticulatus, then as Phalloptychus januarius, 
and now labors under the title of Phalloceros 
caudomaculatus—all very heavy names for such 
a tiny and innocent creature. 
Tor Minnow (Heterandria formosa) 
Found in company with the top minnow 
Gambusia, in the swamps and ditches of our 
southern states, with a range approximately 
from South Carolina to Florida, Heterandria 
formosa long had the reputation of being the 
smallest known fish. Though it has been obliged 
to yield that title to a goby inhabiting a lake in 
the Philippine Islands, it still lays claim to be- 
ing the smallest viviparous fish, the Philippine 
species being oviparous.

JORDANELLA FLORIDAE 
Abundant in the streams and swamps of 
Florida, this little fish, as yet lacking a com- 
mon name, has frequently been shipped north. 
The body color of green is spotted with black 
in both sexes, and in the male with red. The 
food consists of both vegetable «nd animal mat- 
ter, like that of the rainbow fish. The eggs are 
adhesive, and the parents cannot long be trusted 
with them.
