Show 1894.] PROE. R. COLLETT ON A NEW AGONOID E1SH. 673 COLOUR.-Greyish brown, with dark spots and shortish bauds ; belly whitish. On the upper part of head the spots form longitudinal bands-one of these (single) running down in the median line of front, between the eyes. A second (and more distinct) band extends on each side of the snout from the tip to the anterior margin of the eye, hence running under the orbital rim; in some specimens it is continued as a narrow ring round the eye, but commonly this is broken and indistinct. On the opercles and sides of the snout the spots are roundish and well marked. On the body also the spots are roundish, rarely oblong, their size equalling that of the pupil. They are darkest and most distinct on the back, being sometimes almost obliterated on the sides. The colour of the fins is rather indistinct in the badly-preserved specimens before me. The pectorals have a dark oblong spot at their bases (from about 6th to 11th ray) ; the dorsals have two dark bars, separated by whitish, and with the tip in 1st dorsal also blackish (in 2nd whitish). The caudal has a dark cross-bar a little behind the base, and a dark margin. The anal is apparently whitish to the margin in the female ; in the single male specimen at least the outer half is blackish. Measurements (in millimetres). Nos. 1 to 9 are females, No. 10 is a male.
