GILL] NOTEWORTHY EXTRA-EUROPEAN CYPRINIDS 333 
Twenty-five Indian species have been referred by Day to this 
genus, including species with and without barbels, but have been 
separated by others (especially Bleeker) in several genera. A num- 
ber of the species attain a large size and some are quite highly 
esteemed for the table, at least by natives of India. 
The largest species, Labeo gonius, the goni of Bengal, sometimes 
reaches a length of five feet and about seventy pounds. Several 
attain a length of at least three feet, such as the Labeo calbasu 
(Kalbasu of Bengal or kalbans), the Labeo nandina (Nandin of 
Fic. 94.—Labeo calbasu. After Day. 
Bengal), the Labeo rohita or Rohu, and the Labeo dyochilus (Boallo 
of Hindustan). Others range down from two feet to a few inches 
in length. 
The best known of these, at least from an angler’s point of view, 
is the Rohu. A chapter has been devoted to that species (and inci- 
dentally others) by Thomas in “ The Rod in India.” He asserts (p. 
193) that he “ never knew any fisherman, however good at mahseer, 
who had once tried this labeo fishing” with him, who “was not 
fully converted to it as taxing all his skill in a higher degree than 
any other fishing, and as showing sport of a superior order.” 
| According to Day, the Rohu “is esteemed excellent as food, 
propagated with care in ponds in Bengal.” 
One of the largest of the Indian fishes is known as the catla in 
Bengal, and scientifically as the Catla catla or buchanani. It has 
a carp-like form, but the large head is much more arched between 
the eyes and backward there are no barbels. The rami of the lower 
jaw are loosely connected and the dorsal fin is shorter. But the most 
distinctive characters have to be sought for deeper. The pharyngeal 
teeth are in three rows, but none are molariform, and the gill-rakers
