FRESH- WATER FISHES OF SIAM, OR THAILAND 153 



In general appearance, coloration, structure, and habits this fish is 

 a Barilius. Its scales are finer than in any known species of Barilius; 

 its mouth is larger and extends farther backward than in any bariliid 

 species except possibly guttatus; there are no barbels; and the large, 

 broad third suborbital bone is placed entirely behind the eye. These 

 differences, however, are of specific rather than generic significance. 

 The most distinctive feature, and the one justifying separation from 

 Barilius^ is the presence of only two rows of pharyngeal teeth, with 

 5 teeth in the outer row and 2 in the inner row, as against three rows 

 of teeth in all the species of Barilius for which information on this 

 point is available. 



Giintlier (1868, vol. 7) established the genus Bola for the accommoda- 

 tion of this species, overlooking or ignoring the fact that Hamilton in 

 1822 had used the name Bola in another connotation. Jordan (pt. 2, 

 1919, p. 344) proposed the name Raiamas. 



Genus ROHTEE Sykes 



RoMee Sykes, Proc. Zool. Soc. London, 1838, pt. 6, p. 161, 1839. (Type, RoUee 

 ogilbyi Sykes.) 



The citation of this genus in Jordan's Genera of Fishes (1919a, pt. 2, 

 p. 210) is inaccurate in every respect. As the matter is of more than 

 academic interest, this opportunity will be taken to give correct ref- 

 erences. The paper by Sykes is listed by Jordan among papers pub- 

 lished in 1841, and the reference is as f ollow^s : 



Sykes (1840). The Fishes of Dukliun. Ann. Mag. Nat. Hist., IV, William 

 Henry Sykes ; 



RoJitee Sykes, II, 364; orthotype R. vigoesi Sykes. Replaces Osteobrama 

 Heckel. 



The first publication of a paper in which the name RoMee appears 

 was by Sykes in the Proceedings of the Zoological Society of London, 

 1838, pt. 6, p. 161, 1839, meeting of November 27, 1838, issued in 

 May 1839 {fide Sherborn, Index Animalium). The title of the paper 

 was not as cited but was "On the Fishes of the Deccan" (in table of 

 contents). Jordan's reference to "Ann. Mag. Nat. Hist., IV" is 

 incorrect, as the Annals and Magazine of Natural History had not 

 been established at the date shown. The Annals of Natural History, 

 vol. 4, for 1840, contain (pp. 5^62) the identical paper that had 

 appeared in Proc. Zool. Soc. London, 1838, pt. 6, but the internal 

 evidence indicates that it was published in September 1839. Jordan's 

 reference to "II, 364" is to Transactions of the Zoological Society of 

 London, 1841, vol. 2, pp. 349-378, where the article appeared under 

 the title "On the Fishes of the Dukliun." In none of the three papers 

 is there an indication or suggestion that Rohtee vigorsi is the ortho- 

 type. The first reviser, Bleeker (1863 [314]), made "i?. ogilhyp the 

 genotype. Rohtee cannot "replace" Osteobrama because it appeared 

 four years earlier.
