Tlio following account of the genus Arctozenus, Gill, will occur iu Joidau autl Ever- 

 mauu's new manual. 



ARCTOZENUS, Gill. 



Arctuzcnits, Gill, Proc. Ac. Nat. Sci. Phila., 1864, 188. 



Head elongate, conical, the .snout attenuate, the jaws straight, the lower mostly cov- " 

 ered by the upper; teeth of lower jaw anteriorly slender, recurved, and distant; posteriorly 

 small, acute, and close together. This genus is closely related to Sudis, from which it ditt'ers 

 mainly iu the absence of fang-like teeth. From Paralepis it differs in the position of the 

 ventral fins, which are entirely behind the dorsal. The known species belong to the deep 

 waters of Arctic America ; long, slender flsUes suggesting the Barracuda in outline, (apxru^, 

 northern; f^vo?, strange.) 



a. Teeth comparatively strong; Atlantic species A. isorkalis. 



aa. Teeth comparatively weak; Pacific species A. coruscans. 



A. coruscans was described by Jordan and Gilbert, in 1880 (Proc. U. S. N. M., 411), from 

 off Port Townsend, Washington. 



Pago 120 : Paralepis intermedius, Poey, is referred to Sudis. 



Odontostomus atratus, Alcock (Journ. Asiatic Soc. of Bengal, LXii, Part ii. No. 4, 1883, 

 p. 14, PI. IX, fig. 4), was obtained from 128 fathoms in the Bay of Bengal. 



Page 128: Polyipnits splnosiis. The locality of tbe specimen assigned by Alcock to this 

 species was Investigator station 115, and the range of depth was 108 to 220 fathoms — not 

 240, as stated in the text. 



Idiacanthus antrostomus, Gilbert, was obtained by the Albatross in 603 fathoms at 

 station 2980, off the coast of southern California (Proc. V. S. N. M., xiii, 1890, 54), 



Page 129: Halosanrus parvipinnis, Alcock (Ralosauriis parviphmis, Alcock, Ann. and 

 Mag. Nat. Hist., November, 1892, 302). 



This species, represented by a single female, about 15 inches long, with gravid ovaries, 

 taken by the Investigator at station 122, Laccadive Sea, 805 to 880 fathoms, has the scales 

 of the lateral line but little larger than those of the rest of the body, and probably belongs 

 to the restricted genus Halosaurus. 



Page 134: Aldrovandia mediorostris (Giinther) [Challenger Eeiiort, xxii, 239, PI. lix, 

 flg. C]. A single specimen, 17i inches long, was obtained by the Challenger at station 207, 

 west of the Philippine Islands, at a depth of 700 fathoms.

 south of Japan, 50.") fathoms, and the Arabian Sea, 1,000 fathoms. 



A. Hoslcynii, Alcock, loc. cit., is closely allied to, if not identical with, the preceding, 

 and was obtained from 1,000 fathoms in the Arabian Sea. A good figure is given in "Illus- 

 trations of the Zoology of H. M. S. Investigator;^ Pait I, PI. VII, fig. 3, Calcutta, 1892. 



Aldrovandia anguiUiformis [Holosaurus angnilli/orniis, Alcock, Ann. and Mag. Nat. 

 Hist., December, 1889, 453) was obtained by the Investigator in tbe Gulf of Manaar at a 

 depth of 675 fathoms,
