hundred fathoms. A species of this genus was described, under the 

 name Gadus lejjidion, by Eisso,* from Mediterranean specimens. Giin- 

 tber, who referred tbe species to the new genus Ilaloporplnjrus in 18G2,t 

 had a specimen from Madeira. Giinther publisbed preliminary notices 

 of two species, if. rostratiis and H. australis, in " The Annals and Maga- 

 zine of NaturalHistory ", July, 1878, pp. 18 and 19, which were collected 

 by the Challenger. The affinities of the four known species are indi- 

 cated below.

JDescription. — Extreme length of type-specimen (No. 21,837, TJ. S. N. 

 M.) without caudal 0.435'» (17^ inches), with caudal 0.48ij'" : length of 

 collateral type (So. 21,838) without caudal, 0.545'"; with caudal, 0.G03'". 

 Tbe shape of the body resembles that of the species of tbe genus Fhycls, 

 though somewhat shorter, higher, and more compressed, its greatest 

 height contained about five times in its length (without caudal), its 

 height at the ventrals slightly exceeding one-eighth of its total length,
