From Paraplesiops poweri, Ogilby, the only other 
species as yet recorded from the Bay, this fish differs, not 
only by its wholly diverse colour-scheme, but by the 
extremely narrow interorbital region (8.75 in head), the 
additional anal ray, and the more produced ventral. 
NEMIPTERUS THEODOREI, sp. nov. 
(Butterfly Bream). 
Body elliptical, its width about a half of its depth, 
which is subequal to the length of the head and 3.2 in that 
of the body. Snout convex, 2.4 in the length of the head ; 
diameter of eye 1.55 in length of snout and subequal to 
the preorbital width; interorbital width convex, three 
fourths of the eye-diameter. Maxillary not extending 
to level of eye. Lower jaw without canines. Scale 
formula 3/48/9. Dorsal originating above opercular spine ; 
spinous portion low, the spines feebly exserted, gradually 
increasing in length to the last, which is 2.4 in the head 
and 1.33 in the penultimate ray; soft dorsal and anal 
angulate. Caudal forked, upper lobe slightly the longer, 
3.67 in the body-length. Anal originating below 2nd 
dorsal ray; 3rd spine longest, one third of the head 
and 1.45 in the last ray. Pectoral with 17 ray-, 2.33 in 
the body-length. Ventral a little shorter than the pectoral, 
extending to the 2nd anal spine. Gill-rakers 7 on the 
lower branch of the anterior arch. Roseate above, shading 
imperceptibly through the iridescent pink of the sides to 
the pearly white of the lower surface; sides below the 
lateral line with five greenish-yellow horizontal bands, each 
of which occupies the middle of a series of scales, the upper 
and lower bands shorter and less conspicuous than the 
intervening bands; a shining red shoulder spot, covering 
the upper half of two consecutive scales, which vary from 
the 2nd and 3rd to the 4th and 5th below the lateral line. 
Upper surface of head with a tinge of lavender overlying 
the pink; a curved light blue bar from the front of the 
eye, passing along the upper edge of the preorbital and 
anteriorly changing gradually to a deep violet; a similar 
but less conspicuous band along the lower edge, continued 
as a violet band along its free border; upper lip yellow; 
cheeks and opercles pink with golden reflections; a 
distinct greenish blue spot, preceded by a purplish spot,
