392 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



Tbo form identified Tiy GiiTitlier with the Caiiarian species of Webb and Berthelot was 

 obtained 90 miles southeast of Cape St. Vinceut, at a depth of 1,090 fathoms, lie 

 believes it to be the same as the Mediterranean species placed under the name by Vincigu- 

 erra. The French explorers obtained 141 specimens off Morocco, Soudan, and the Canaries, 

 at 500 to 2,G00 fathoms. 



Maerurus smiliophorus, Vaillant (242, PI. xxii, Fig. 1), is very close to M. sclerorhytichus, 

 as may be seen by comparison of his figure with that of Viiiciguerra. The differences in 

 the squamation and in the form of tlie sagitta do not appear to be sufficiently demonstrated 

 to warrant the acceptance of his species. AH his specimens were obtained from the region 

 region inhabited by 31. sclerorhynchun, IST. Atlantic, 4G0-1319 meters.

Snout conical, projecting beyond the mouth, witli rather obtuse and rough upper 

 edge; the left of the mouth extends nearly to below the center of the eye. The teeth of 

 the outer series are visibly stronger than the remainder. Barbel slender, but not so long as 

 the eye. The upper profile rises rather .suddenly towards the anterior dorsal spine. The 

 interorbital space is flat, its width being considerably less than the diameter of tlie eye, 

 which conspicuously exceeds the length of the snout, and is one-third or rather more 

 than one-third the length of the head. The scales are equally rough over the whole 

 of their surface, the spiuelets being .subequal in size, densely packed, but arranged in 

 from 8 to 12 series, the middle series not being more prominent than the others (as is 

 the case in Maerurus .iclerorhynchus). The entire margin of the scale is spinous. There 

 are 8 .scales in a transverse series between the first dorsal and the lateral line. Second 

 dorsal spine somewhat produced, armed along its anterior edge with barbs pointing 

 upwards and rather closely set. The second dorsal fin commences at a distance from the 

 first which is less than the length of tlie head. Tlie outer ventral ray not, or but slightly, 

 produced. Lower part of the head and aiitero-superior portion of the first dorsal black.

The Challenger obtained 2 specimens, 8 to 9 inches long, Giinther's types, from 600 

 fathoms south of the coast of Portugal. The .species is very close to M. rudis, Giinther, 

 from the Kermadec Islands in the Pacific. 



MACRURUS SERR.A.TUS, Lowe. (DonUtful species.) 



Macrnrua serratus, Lowe, Proc. Zool. Soc, London, 1843, '91 ("a single specimen, which was not seen until 

 it bad been partly dried.")

 The description quoted above is very indefinite: Giintlier places the name of Lowe doubt- 

 fully in the synonymy of M. a'qnalis. It is closer, however, to M. sclerorln/nchus, having a 

 filament at the tip of the ventral ray. Giinther states that the form of which Wyville 

 Thomson gave a figure under the name of C'oryplKvnohles serratus was M. (cquaUs.^
