Sciaena aquila (Lacep.). 



[? Sciaena hololepidota (Lacep.).] 

 St. 274. 4. viii. 27. Off St Paul de Loanda, Angola. Large otter trawl, 64-65 m. : 3 specimens, 



275-295 mm. 



Sciaena angolensis, sp.n. 



St. 274. 4. viii. 27. Off St Paul de Loanda, Angola. Large otter trawl, 64-65 m. : 4 specimens, 

 240-260 mm. (holotype, 240 mm.). 



Depth of body 3f to 3I in the length, length of head about 3. Snout shorter than eye, 

 diameter of which is 3! to 3 1 in length of head and about i\ times interorbital width. 

 Snout obtuse and rounded ; jaws equal anteriorly; maxillary extending to below middle 

 of eye or a little beyond ; 2 pairs of open pores beneath the lower jaw ; teeth in villiform 

 bands anteriorly, tapering laterally to a single series ; those of outer row in upper jaw

enlarged, becoming canine-like anteriorly; those of inner row of lower jaw moderately 

 enlarged. Margin of praeoperculum with some minute denticulations along posterior 

 edge; angle rounded, with some larger and more distinct teeth; operculum with two 

 weak, flat spines. 9 or 10 gill-rakers of moderate length on lower part of anterior arch. 

 Scales finely ciliated ; 47 to 49 in lateral line, 5 or 6 from origin of dorsal to lateral line ; 

 lateral line tubules with 3 to 5 short branches. Dorsal IX, I 29-30 ; spines slender, 

 fourth longest, about f length of head; soft dorsal scaled only at base. Anal II 7; first 

 spine very short ; second stronger than those of dorsal fin, length more than \ that of 

 head. Pectoral about | length of head. Pelvics shorter, f length of head. Caudal 

 pointed, middle rays f to | as long as head. Silvery; back darker; dusky patches on 

 opercular region ; a dark spot superiorly in axil of pectoral ; dorsal fins with blackish 

 margins ; pectorals, anal and caudal more or less dusky. 



Apparently most nearly related to S. aquila (Lacepede), differing mainly in the some- 

 what larger scales, larger eye, pointed caudal fin, etc.
