Originally described from Tadi Stream, Nakon Sritamarat, from 

 two specimens taken in July 1928, this species has since been found 

 to be widely distributed, not only in the Peninsula but also Central, 

 Northern, Eastern, and Southeastern Thailand. 



A length of 15 cm. is attained, but full sexual maturity is reached 

 at less than half that size. 



The development of tubercles on the snout and of pearl organs on 

 head and body is marked in both sexes, but is more pronounced in 

 the males. Other secondary sexual characters are the length of the 

 anal fin and the length of the barbels. 



Among numerous specimens taken by Deignan in tributaries of 

 the Nan River in Northern Thailand in June 1936, the largest in one 

 lot are two females, 5.8 and 6 cm. long, with nearly ripe eggs, the 

 ovaries extending as far forward as the base of the pectoral jBns, and 

 two males, 6.1 and 6.9 cm. long; the prickliness of the rostral tubercles 

 is much greater in the males ; and the depressed anal fin reaches the 

 caudal rays in some of the males but in none of the females. In an- 

 other lot, two females, 6.8 and 7.7 cm. long, with well-developed ova, 

 have every scale on the body as well as the upper entire part of the 

 head thickly beset with minute pearl organs. 



It is believed that Garra spinosa Fowder, described from numerous 

 specimens, 3.4 to 9 cm. long, from several localities in Northern 

 Thailand, is the present species. The principal characters ascribed 

 to the species were : 29 to 31 scales in the lateral line, rostral barbel 

 as long as eye, large pearl organs on snout and smaller ones covering 

 upper surface of head and predorsal region, a broad dark band along 

 the side from head to caudal fin, and dorsal fin variously banded ac-
