ANTARCTIC FISHES OF THE SCOTTISH NATIONAL ANTARCTIC EXPEDITION. 317 



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.E. 



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

 Synaphobranchus bathybius (part.), Giinth., "Challenger" Deep-Sta 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 Histiobranchns, Gill, which includes also S. bathybius, Giinth., and 

 S. mfernalis, Gill. All three are closely related, differing 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 . . . . . . . . . bathybius. 



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 ...... infemalis. 



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 2j 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- 

 incc to the sub-family Macrurinfe (cf. Ann. Mag. Nat. Hist. (7), xi., 1903, pp. 45S-466), 

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

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.
