The following account of the genus Arrtozenus, Gill, will occur in Jordan and Ever- 

 maun's new manual. 



ARCTOZENUS, Gill. 



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



Head elongate, conical, the snout attenuate, the jaw.s 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 differs 

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

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

 ■waters of Arctic America ; long, slender fishes suggesting the Barracuda in outline. («,oxr«-, 

 northern; f^i-"?, strange.) 



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



aa. Teeth comparatively weak ; Pari fic species A. coruscans. 



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

 off Port Townsend, Wasbiugton. 



Page 120: Paralepis intcniicdius, Poey, is referred to Suclis, 



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

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



Page 128: Folyipnits spinosiis. The locality of the 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 G03 fathoms at 

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



Page 129: Halosaiiriis parmpinnis, Alcock {Halosaurus parvipinnis, Alcock^ Ann. and 

 Mag, Nat. Hist., November, 1892, 362). 



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 Halosaifrus. 



Page 134: Aldrovandia mcdiorostris (Giiuther) [Challenger Eeport, 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. 



Page 132: Aldrorandia «,^h is (Giiuther, Ann. and Mag. Nat. Hist., 1877, 444; Chal- 

 lenger Eeport, XXII, 241, PI. Lix, flg. b: Alcock, op. cit., October, 1890, 309) is recorded from 

 soutb of Japan, 505 fathoms, and the Arabian Sea, 1,000 fathoms. 



A. HosJiynii, Alcock, h>c. 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,-' Part i, PI. vii, flg. 3, Calcutta, 1892. 



Aldrovandia anguilliformis {Eolosaurm anguilliformis, Alcock, Ann. and Mag. Nat. 

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

 depth of 675 fathoms.
