CLUPEA VARIEGATA, Sp. nov. 
Desise Pots. VS: A, B26. C2t7. Le 1. 90. 
Length of head 2, of pectoral 4, of caudal } of the total length. 
Height of body 4 of the total length. 
Eyes with broad adipose margins. Diameter } of length of head, 
? of a diameter from end of snout, above 1 diameter apart. 
Abdominal profile more convex than the dorsal. 
Jaws of about equal length ; the posterior extremity of the maxilla 
extends to beneath the centre of the orbit. Opercles smooth. 
Teeth on tongue; none on jaws, vomer, or palatines. 
Fins. Dorsal commences rather nearer to the snout than to the 
base of the caudal. Ventrals situated opposite the commencement of 
the dorsal fin. Anal in the posterior third of the distance between 
the posterior margin of the orbit and the base of the caudal fin. 
Scales regularly arranged behind a line from the opercles to the 
base of the anal fin, anterior to which they are very irregular. 
Along the back to the base of the dorsal fin the scales of the two sides 
meet, so as to form a sort of line somewhat resembling a lateral 
line in appearance. Serrated scales commence under the middle of 
the pectoral; ten are posterior to the ventral fin, and ten anterior 
to it. 
Colours. Silvery glossed with gold. A dark humeral spot. A 
row of about eighteen bars passes across the back and descends a 
short way over the sides. Dorsal fin with a black band in the lower 
portion of its posterior half. End of tail tipped with black. 
Hab. Irrawaddi and its branches. Many specimens procured, up 
to 7 inches in length. 
PELLONA SLADENI, sp. nov. 
ee. BM. VW Ane eaala. Te). 48. 7, ted, 
Length of head 7 of length of body, and equal to its height. 
Eyes with wide adipose lids. Diameter } of length of head, 
1 diameter from end of snout. 
Ridges on the head slightly diverge posteriorly. Lower jaw very 
prominent. 
Fins. First two dorsal rays in advance of anal, the remainder of 
the fin over it; it arises midway between the base of the caudal and 
the posterior extremity of the opercle. Pectoral reaches to nearly 
the end of the veutral, which is small. Caudal forked. Twenty 
spinate scales exist on the abdominal profile anterior to the ventral 
fins, and eleven posterior to them. 
Colours. Silvery ; opercles golden. Caudal edged with black. 
Specimens up to 7 inches from the Irrawaddi, at Mandalay. 
I have named the species after Major Sladen, Political Resident 
at the court of the King of Burma, who greatly assisted me in col- 
lecting specimens, as well as in acquiring information on the fishes of 
that mismanaged but magnificent country.
