Bathygadus Jongijilis. 



Baili>jgadus longifilis, Goode and Bean, Proc. U.S. Nat. Mus., vol. viii., 188G, \). 599. 

 D. 10-11. P. 13. V. 8. 



The eye is one-fourtli of the length of the head, equal to that of the snout, and rather 

 less than the width of the interorbital space. Maxillary extending somewhat behind the 

 eye. Barbel longer than the eye by one-half. The anterior dorsal spine, the upper 

 pectoral ray, and the outer ventral ray produced into long filaments. About twenty-five 

 scales in a row from the vent upwards and forwards to the dorsal fin. Gill-rakers very 

 long and slender, 7 + 28. Yellowish-grey; abdomen bluish. 



Evidently closely allied to Bathygadus multifiUs. 



Habitat. — Specimens were obtained by the U.S. Fish Commission in lat. 28° 47' N., 

 long. 87° 27' W., at a depth of 724 fathoms ; the}- were 8 inches long. 



Macruroniis. 



Macruronus, Giinth., Zool. Record, vol. viii., 1873, p. 103. 



Head and bod}' compressed, covered with cycloid .scales ; trunk not abbreviated. 

 Bones of the head rather firm, with narrow cavities. Eye large ; snout rather ])ointed ; 

 mouth wide, lateral. Teeth in the upper jaw biserial, those of the outer series and those 

 of the single mandibulary series strong. Gill-membrane slightly united in front ; seven 

 branchiostegals ; four gills with tlie gill-laminae well developed ; the first branchial arch 

 free, with long lanceolate gill-rakers. Rays of the second dorsal well developed throughout 

 its lencfth. Barbel none.'

Macruronus novas-zelandiiP. 



Coryphsenoides novx-zelandise. Hector, Trans. New Zeal. Inst., vol. iii. p. 136, pi. xviii. fig. 1 ; 



Huttoii, Fish. N. Z., p. 49. 



Of this fish I have examined specimens from New Zealand, Tasmania, and the Messier 

 Channel, the largest being nearly 2 feet long. All of them seem to have been caught 

 near the surface and at no great distance from the shore, and it is not probable that 

 it descends to the same great depth as the other Macruri. Like Lepidopus, it seems to 

 live for the greater part of the year at a small depth, and to periodically approach the 

 shore at certain seasons. Hutton says that it is thrown up in large quantities on the 

 shores of Cook Straits after heavy gales. 



' Botli Hector and Hutton describe or figure this fish with a barbel, whilst I cannot detect a trace of it in our 

 specimens. Some misunderstanding by the artist must have occurred, as, at any rate, the bifid barbel could not be at 

 the place where he has drawn it.
