ZOOLOGICAL SOCIETY BULLETIN 95 
The appearance of this species can be judged 
from the fact that a lady once asked if some D. 
rerios at the Aquarium were baby striped bass! 
One and a half inches is their maximum length, 
and they are sometimes called zebra fish. 
D. rerio from Ceylon, and D. malabaricus 
from the Malabar coast region of India, both 
show blue coloring, D. rerio having broad 
stripes of brilliant blue across a ground color 
of yellowish in the male, and silver in the 
female, the dorsal and pectoral fins of the male 
being gold, of the female colorless. D. malabar- 
icus has a blue body with salmon stripes and is 
the largest Danio brought to this country. 
In D. analipunctatus the male has blue and 
yellow borders on his fins. D. albolineatus, as 
its name suggests, is striped with white. Some 
regard it as the handsomest of all, while others 
deem D. malabaricus the handsomest. 
The males of all species are smaller, more 
slender and more highly colored than the 
females, and all of the Danios are provided 
with two long, hair-like barbules on the lips. 
THe Barprers 
The fishes of the genus Barbus are chiefly re- 
markable for their large and handsome scales, 
seemingly so disproportionate to the size of the 
fish. This is so characteristic of the genus that 
one yery large species, B. mosal, common to the 
mountains of Asia and attaining a length of 
from four to six feet, develops scales as large 
as those of the tarpon—the size of the palm 
of one’s hand. All have breeding habits simi- 
lar to the goldfish excepting B. viviparous from 
Natal, which, as indicated by 
its name, brings forth its 
young alive. 
A half dozen or more toy 
species of Barbus from India 
are familiar to 
aquarists, B. conchonius be- 
American 
ing one of the largest and at- 
taining three inches in 
length. They are all hardy ir 
captivity. The adhesive eggs 
laid among aquatic plants. 
hateh in from thirty-six to 
forty-eight hours in a temp- 
erature of from 70 to 75 de- 
grees and it is not safe to 
leave them with the parents. 
The young mature in from 
four to six months, and 
should be fed the same as 
goldfishes.

The distinguishing marks of a few of the 
commonest species are as follows: 
Barbus semifasciolatus, gray-green with black 
bars and red fins. 
B. conchonius: one black spot near the tail 
In the male a black spot in front of the dorsal 
fin. The male turns red in the breeding season. 
B. vittatus: black spot on caudal peduncle, 
and a black vertical line through dorsal fin. 
B. phutunio: blue-black spots, fins orange. 
B. ticto: two black spots, one near tail and one 
at the back of the gill cover. Fine black mark- 
ings in dorsal fin of male. Otherwise this 
species is similar to B. conchonius. 
Japranese Loacn or Doso 
Few fishes from foreign parts are better 
known in this country than the long and slender 
Dojo (Misgurnus anguillicaudatus), which at- 
tains a length of about six inches and habitually
