548 SURGEON F. DAY ON INDIAN FISHES. [Nov. 25, 
differences are nevertheless very conspicuous. The yellow margin 
around the red skull-cap is very distinct in Pt. porphyraceus ; 
very faint and pale in Pt. fasciatus. The median abdominal spot, of 
a dark blackish violet in Pt. porphyraceus, is of a purplish wine-red 
in Pé. fasciatus. The chin and upper part of throat are of a pure 
white in Pt. fasciatus, of a pale yellow in Pt. porphyraceus; and, 
lastly, in Pt. porphyraceus we miss the greyish-lilac anteapical spot 
in the longest scapulars, so conspicuous in the allied species.

One specimen; without the rufous pectoral band. It is certainly 
disagreeable to kill one’s own children ; but as to Rallus forsteri we 
are fully convinced of our error. In a set of specimens from the 
Pelew Islands, some had the rufous pectoral band, in two others it 
was entirely wanting, and in one bird there was only to be seen faint 
traces of it.

3. Remarks on some of the Fishes in the Calcutta Museum. 
By Francis Day, F.Z.S. & F.L.S.—Part IT. 
I have already forwarded to the Society a communication relating 
to some of the fishes in the Calcutta Museum, which appeared to 
me to be entirely new or imperfectly known, and I now propose to 
offer some remarks upon the Cyprinide in the same collection. 
Genus Apva, Blyth. 
Body elongated and compressed. A small, erectile, bifid sub- 
orbital spine. Eight barbels—one rostral, one maxillary, and two
