FRESH-WATER FISHES OF SIAM, OR THAILAND 123 



to be some error, however, as J. R. Norman, of the British Museum ( in 

 a letter to the writer dated October 2, 1933), stated that there is no 

 specimen of Z. imlanotaenia from Thailand in the British Museum, 

 which has only the types, although there is an example of L. hoevenii 

 from Bangkok. 



These two forms are very similar, differing almost entirely in the 

 number of scales in transverse series. The black lateral band, which 

 seems to characterize L. tnelanotaema at all ages, is present in L. 

 hoevenii up to a length of 15 to IT cm, or sometimes longer. 



Genus ASPIDOPARIA Heckel 



Aspidoparia Heckel, in Fenzl, Abblld. Thiere Pfl. Syr., Fische, p. 186, 1&43. 

 (Type, Aspidoparia sardina Heckel.) 



The fishes of this genus may be readily recognized by the peculiar 

 mouth (absence of lower lip, lower jaw with a sharp, crescentic bony 

 edge), absence of barbels, broad ring of suborbital bones, greatly de- 

 curved lateral line running in the low^er half of the caudal peduncle, 

 dorsal fin arising well behind the ventrals and having no osseous rays 

 and 7 or 8 branched rays, anal fin with 9 to 12 rays of which 7 to 10 are 

 branched, and pharyngeal teeth plow-shaped and in 2 or 3 rows. 



The first references to these fishes in scientific literature appear to 

 have been by Hamilton (1822), who placed one of the two Indian 

 species in the composite genus Chela and called it mora?% and the 

 other in the composite genus Cdbdio and called it jay a. Bleeker ( 1863 

 [314]) made morar the type of his genus Morara (1859) and at the 

 same time recognized Aspidoparia of Heckel (1843) and indicated A. 

 sardiTia as the type, unaware that Morara was a synonym of Aspido- 

 paria and sardina a synonym of morar. To add to the confusion, Jor- 

 dan (1917, pt. 1, 115) apparently intended to validate Gabdio and desig- 

 nated i(2y«, "the first species named," as the type, although it had long 

 been known that jaya is an Aspidoparia. Jordan's action may, how- 

 ever, have served the useful purpose of making Gabdio unavailable for 

 any of the other mixed lot that Hamilton included under this name. 



In addition to the single species known from Thailand, another has 

 been ascribed to that country and is here considered, although it is 

 quite obviously not entitled to a place in this genus, and its exact 

 status remains to be determined. 



ASPIDOPARLA. MORAR (Hamilton) 

 Cyprinus morar Hamilton, 1822, p. 264, pi. 31, fig. 75 (Yamuna and Tista Rivers). 

 This common species of Burma and India, not previously reported 

 from Thailand, was to be expected in parts of Thailand contiguous 

 to Burma. A specimen 7.8 cm. long was taken by Deignan in the 

 Salwin at Ta Ta Fang, October 14, 1936. It agrees with Day's descrip-
