202 ''ENDEAVOUR" SCIENTIFIC RESULTS. 



Head smooth above, with or without an obscure 

 rugose area on each side of the occiput. Preopercular 

 spine not curved upwards at the tip, its inner edge with 

 about ten small serrations, the outer with a strong 

 antrorse spine near its base. Upper lip covered by the 

 preorbital when the mouth is closed. Maxillary extend- 

 ing backward a little beyond the vertical of the nostril, 

 which is placed a little in advance of the eye. A baud of 

 villiform teeth in each jaw. Gill-opening exposed, mid- 

 way between the hinder margin of the eye and the 

 upper base of the pectoral. 



All the dorsal spines are filamentous, the third and 

 fourth reaching backward almost to the base of the tail. 

 The second dorsal is elevated, and all its rays are bifid ; 

 the last is divided to its base, and each branch is bifur- 

 cate. Most of the anal rays are simple, only the two 

 branches of the last being bifurcate. Upper pectoral 

 rays slightly longer than the second, the ninth and tenth 

 rays longest and almost reaching the vertical of the 

 fourth anal ray; all but the outer rays are bifurcate. 

 Ventrals large, reaching beyond the base of the second 

 anal ray; the inner ray is so deeply divided as almost to 

 appear as two. Caudal large and rounded, most of its 

 rays bifurcate. Lateral line originating in advance of 

 the gill-opening; it curves inwards towards the back 

 above the pectoral fin, and extends backward on the 

 dorsal rather than on the lateral surface. 



Colour-marking. Head and body rather obscurely 

 marbled above, the markings enclosing some lighter 

 spots ; an obscure darker band crosses the nape, and there 

 are indications of others on the back. Lower parts white. 

 First dorsal grey, the membrane profusely ornamented 

 with fine lines enclosing lighter coloured stripes and 

 spots, many of which are sinuous or somewhat angular 

 in form ; the membrane is blackish near the first spine. 

 Second dorsal with many fine parallel lines crossing 

 it obliquely, some of which coalesce to form broad dark 

 angular markings and enclose incomplete ocelli. Outer 

 half of anal blackish, with some indistinct lines and 

 spots; basal portion white. Caudal with tAvo broad dark 

 cross-bauds, and many narrow longitudinal stripes; the 

 membrane between the lower rays is dusky, with small 

 darker spots. Ventrals dusky, with irregular bars across 

 the rays, and numbers of small dark spots. Pectorals 

 with a few grey spots.
