Leuciscus neglectus, Selys’ Faune Beige, is distinguished from L. idus, 
L., by its longer head, lower body, deeper cleft caudal fin ; the lateral 
lines consisting of fifty-five scales, while in the idus sixty are present ; 
found at Brussels. L. rutiloides, id. ib. ; D. 12 ; A. 13 ; length 5" 9'" ; 
fins yellow : perhaps only a variety of L. rutilus. 
Aspius alhurnoides, id. ib. ; D. 11 ; A. 19-21 ; fifty scales on the 
side line, eight rows above, four beneath : nearly allied to A . alburnus. 
Ahramis Hechelii, id. ib. ; D. 13 ; A. 19-20 ; lateral line has forty-eight 
to fifty-three scales, ten rows above it, five below: A. Btiggenhagii (?), 
Yarrell ; 8" 10'^'. 
Cobitis bontonensis, M‘CleUand, 1. c. p. 586 ; snout somewhat com- 
pressed ; lips fringed ; six barbules ; D. 8 ; P. 11 ; V. 8 ; A. 6 ; C. 18 : 
Boutan at the Mishmee Mountains. 
Platycara anisura, id. ib. ; caudal fin entire, sickle-shaped posteriorly, 
as the under rays are shorter than the upper ; five rudimentary barbules 
in front of the mouth, two at the corners ; D. 10 ; P. 21 ; V. 11 ; A. 7 ; 
C. 19. P. lissorhynchus has a disc behind the mouth ; snout smooth 
and round ; caudal fin four-cornered ; D. 9 ; P. 18 ; Y. 9 ; A. 6 ; C. 19 : 
both species are from the Kasyah Mountains. 
J. Muller has arranged, in his family of the Characinm^ a 
new genus, Hemiodus. 
A row of teeth on the intermaxillary like round leaflets, serrated 
at the margin ; no teeth in the under jaw ; adipose fin. The species, 
H. crenidens, from Brazil, is Salmo tinimaculatus, Bloch. (Monats- 
berichte der Acad, zu Berlin, 1842, p. 106, and Miiller’s Archiv. 1842, 
p. 324.) 
J. Muller separates the genus Erythrinus, as it is defined 
by Agassiz, into two suh-genera. 
The one, Erythrinus, Cuv., MiilL, has simple hackle-formed palate 
teeth ; the larger dog teeth, under the jaw teeth, are proportionably 
short ; the swimming-bladder cellular. E. unitceniatus, Ag. {Synodus
