ANTARCTIC FISHES OF THE SCOTTISH NATIONAL ANTARCTIC EXPEDITION. 235 



but the form of the skull, the produced jaws, and the different mandibulary and palatine 

 dentition distinguish it from that genus ; the antrorse palatine teeth are especially 

 peculiar. 



The dentaries of a second specimen were taken at the same locality. 



APODES. 



Synaphobranchid^. 



13. Synaphohranchus australis, sp. n. (PI. VIII. fig. 5.) 

 Synaphobranchus hathybius (part.), Giinth., " Ghallenger" Deep-Sea Fish, p. 254 (1887). 



The Challenger specimen, 350 mm. in total length, was taken midway between the 

 Cape of Good Hope and Kerguelen, at a depth of 1375 fathoms, The Scotia example 

 was obtained on 13th April 1904, at Station 451, in 48° 06' S., 10° 5' W., at a depth 

 of 1742 fathoms, and measures a total length of 470 mm. The species belongs to 

 the sub-genus Histiohranchus, Gill, which includes also S. hathyhiiis, Giinth., and 

 S. infernalis, Gill. All three are closely related, diifering as follows : — 



Eye nearer to end of snout than to angle of mouth ; origin of dorsal above base of 

 pectoral, its distance from end of snout rather less than ^ that from end of 

 snout to vent .......... hathybius. 



Eye about equidistant from snout and angle of mouth ; origin of dorsal above 

 posterior part of pectoral, its distance from end of snout somewhat more than 

 \ that from end of snout to vent ...... infernalis. 



Eye about equidistant from snout and angle of mouth ; origin of dorsal a little 

 behind end of pectoral, its distance from end of snout about 2^ in that from 

 end of snout to vent ......... australis. 



ANACANTHINI. 



Macrurid^e. 



Four species of this family were obtained by the Scotia in Antarctic seas, all belong- 

 ing to the sub-family Macrurinse (cf. Ann. Mag. Nat. Hist. (7), xi., 1903, pp. 459-466), 

 and to genera with the teeth in the lower jaw uniserial.

Res. Voy. " Belgica," Poiss., p. 44, pi. vii. (1904) ; Proc. Roy. Soc. Edin., xxix , 1909, p. 488. 



The type was taken in 70° 40' S., 102° 15' W., depth 1526 fathoms. The Scotia 

 examples are from : (1) Station 313, 62° 10' S., 41° 20' W., 1775 fathoms; temperature 

 31-0° F.; trawl; 18th March 1903. (2) Station 451, 48° 06' S., 10° 05' W., 1742 

 fathoms; 13th April 1904..
