PBOF. B. COLLEM OH A NEW AGONOID FISH. 



673 



CoLOUB. — G-reyish brown, with dark spots and shortish bands : 

 belly whitish. 



On the upper part of head the spots form longitudinal bands — 

 one oE 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. 



Ova. — Several of the females were filled with ripe ova ; their 

 number in the two ovaries together about 3000. The roe had a 

 diameter of 1*2 miUim. ;
