EEGAN — MARINE FISHES. 239 



127. Flatycephaliis graiidisquamis, sp. n. 



Depth of body 5^ in the length, length of head 2|. Snout a little shorter than eye, 

 the diameter of which is 3 in the length of head and 1 times the interorbital width. 

 Maxillary extending to below anterior \ of eye ; vomerine teeth in 2 separate patches. 

 Head with several spines ; 2 on the snout, 1 or 2 in front of each orbit ; supraorbital 

 ridges serrated except anteriorly ; behind them on each side a more or less regular 

 transverse series of 3 or -1 spines, which ai-e followed by a larger spine on each parietal, 

 with a small one hehind it ; a serrated ridge behind the middle of each oi'bit ; a series of 

 3 post-temporal spines ; suborbital ridge serrated througbout, ending in a prajopercular 

 spine of moderate length, below which are two others. Two opercular spines and one 

 on the clavicle. 1 gill-rakers on the lower part of the anterior arch. 30 scales in a 

 longitudinal series ; only the anterior 3 or 4 scales of the lateral line spinate. Dorsal 

 IX, I 10. Anal 11. Ventrals extending to the fourth anal ray. Caudal suhtruncate. 

 BroAvnish, with dusky bars or marblings ; pectoral blackish posteriorly in its lower half; 

 ventral with 2 blackish ci'oss-hars, one near its tip. 



Seychelles Group, Amirante, 30 fathoms. 



A single specimen, 73 mm. in total length. 



The three preceding species, are allied to the Japanese P. spinosus, Sclileg., and 

 P. macrolejiis, Blkr., and differ from others of the genns in the large size of the scales. 



Hoplichthyidae. 



128. Hoplichthys acanthop)leurus, sp. n. (Plate 28. tig. 5.) 



Length of head 3^ to 3^ in that of tlie fish. Snout slightly longer than eye. the 

 diameter of which is 3f in the length of head. Interorbital region very narrow, bordered 

 by denticulated ridges, all the ridges on the head denticulated. Maxillary extending to 

 helow anterior margin of eye or a little beyond. 12 gill-rakers on the lower part of 

 the anterior arch. 27 scutes in a longitudinal series ; each scute with a well-developed 

 spine and a second very small spine below it. Dorsal VI, 15 ; spinous dorsal scarcely 

 higher in the male than in the female, the spines not produced ; second dorsal, in the 

 male, with all the rays produced into filaments, increasing in length from the first to the 

 third, which is nearly as long as the head, thence decreasing to the fifth and again 

 increasing to the seventh and eighth, whicli are as long as the third, thence decreasing 

 to the tenth, and again from the twelfth to the last. Anal 17. Caudal truncate. 



Saya de Malha Bank, over 123 fathoms. 



Two specimens, c? & ? , 180 mm. in total length. 



This species is very near to the recently described H. cUrimis, Gilbert, from the 

 Sandwich Islands, males of which have the first dorsal spine produced and filamentous, 

 and only the four anterior rays of the second dorsal produced into filaments. 



The name Hoplichthys gllberti may be given to the species described from Japan by 

 Gilbert as H. langsdorjii, C. & V., and which differs from S. citrinus in having none of 

 the rays produced in the males. I have examined several specimens of the true 

 S. langsdorjii, in which each lateral scute bears two strong subequal spines.
