64 THE VOYAGE OF H.M.S. CHALLENGER. 



Pagrus major, Schleg., off Inosima, from Japanese fislier-boats, Harbour of Oosima. 



Pagrus cardinalis, Lac., Market of Yokohama. 



Clirysophrys swinhonis, Gthr., Inland Sea of Japan, Market of Yokohama. 



Hoplegnathus fasciatus, Schleg., Inland Sea of Japan. ■> 



Sehastes ventricosus, Schleg., Market of Yokohama. 



Sehastes oblongus, n. sp. (PI. XVIII. ). , 



Allied to Sehastes inermis and 2Xichycephalus. 



D. 12/jij, A. f, L. lat. ca. 65. The height of the body is contained thrice and one- 

 half in the total length (without caudal) ; the length of the head twice and three-fifths. 

 The scales are rather irregularly arranged, and much smaller above than below the lateral 

 line. On the upper side of the head they advance to the nostrils, very minute ones 

 covering even the prseorbital. The snout is pointed and longer than the eye, the 

 diameter of which is one-sixth of the length of the head, and equal to the width of the 

 flat interorbital space. None of the spines on the upper side of the head project, and 

 those of the prseoperculum are obtuse ; the teeth form broad villiform bands in the jaws 

 as well as on the vomer and palatine bones ; the maxillary reaches to the vertical from 

 the hind margin of the eye. Dorsal spines strong ; the fourth to the seventh are the 

 longest, two-fifths of the length of the head. Anal spines stronger, but much shorter than 

 the longest of the dorsal. Brownish, marbled with darker ; lower parts and all the fins 

 with brown spots ; an oblique brown streak from the praeorbital towards the angle of the 

 praeoperculum. Inland Sea, Japan. Market of Yokohama. 



Sehastes joyneri, Gthr. (Ann. and Mag. Nat. Hist., 1878, vol. i. p. 485). (PL XXIX. 

 fig. A.) 



D. -^1, A. f , L. lat. ca. 60. The heiglit of the body is equal to the length of the head, 

 and one-third of the total length (without caudal) ; scales very thin, scarcely serrated, a 

 little smaller above the lateral line than below it ; on the upper side of the head they 

 advance to the nostrils and cover the prseorbital and maxillary. Snout short, three- 

 fourths of the diameter of the eye, which is three-tenths of the length of the head, and 

 exceeds by one-third the width of the interorbital space which is flat. Upper surface of 

 head smooth, scarcely armed, the two occipital ridges very low and terminating in short 

 spines ; prseorbital with two flat spines ; prseoperculum with five spines, the second 

 from above being the longest, and one-third of the diameter of the eye ; operculum with 

 two spines, the upper of which is the longest. Teeth in narrow viUiform bands, in the 

 jaws, on the vomerine and palatine bones ; the vomerine teeth form a triangular patch. 

 The maxillary does not reach to the vertical from the middle of the eye. The fourth 

 dorsal spine is the longest, contained twice and a quarter in the length of the head. Anal 

 spines stronger than those of the dorsal, the second anal spine being shorter than the
