52 DEEP-SEA FISHES OF THE ATLANTIC BASLN. 



Argentina hebridica, Nilsson, up. tit., 474. — Capello, Peix. Portugal, 35. 

 Argentina Cuvieri, Cuvier and Valenciennes, Hist. Nat. Poiss., xxi, 41S. 

 Argentina Tarrellii, Cuvier and Valenciennes, Ic. c, xxi, 41S. 

 Argentina lioglossa, CUVIER and VALENCIENNES, 7c. c. 

 Argentina decagon, Clarke, Trans. New Zealand Inst., xi. 1879, 295. 



Height of body one-eighth of its entire length, with head 4 to 4J in same; eye 3 in head, 

 and less than or equal to the length of the snout. Ventrals nearly median and under 

 dorsal. Scales minutely spinigerous, almost smooth in young. Head scaleless, diaphanous. 



Radial formula : 1). 10-12; A. 12; P. 14; V. 11; L. lat. 52. 



This form is abundant in shallow water in the Mediterranean and Adriatic, where it is 

 often taken by the fishermen. It is kuowu also oft Portugal and in the northeastern Atlan- 

 tic from Scotland to 61° and beyond. In Norwegian waters it occurs in the depths, Collett 

 haviug obtained it in 200 fathoms. This distribution is paradoxical, and is referred to in 

 another place. 



A. sphyrcena spawns in April in the Mediterranean. 



Giinther considers A. decagon from Eokitika, New Zealand, to be the same form. 

 Giglioli, after studying an extensive series obtained by him at Messina, has decided that 

 A. lioglossa, C. & V., is also identical with A. sphyrcena.

Argentina syrtensium, Goode and Bean, Proc. U. S. Nat. Mus., i, 1875, 261. 



Height of body 5J in its total length, with head 4 to 4 ^ in same. Eye, 3 in head and 

 longer than snout. Ventrals median, and under dorsal. Scales strongly spinigerous. 



Radial formula: D. 11; A. 14; P. 17; V. 12. Scales, 3i, 66, 4. (A full description with 

 measurements given by Goode and Bean, loc. cit.) 



This form occurs in Norway at depths of It'll fathoms ami less. The first taken in North 

 America — the type, of A. syrtensium, Goode and Bean (U. S. X. M , No. 21624) — was found 

 in the stomach of a Phycis from Sable Island Bank, in 200 fathoms. In July, 1891, a 

 specimen 18 inches long (TJ. S. N. M.. No. 4370S) was caught by a boy with a hook and line 

 in the harbor of Belfast. Mr. Another. No. 37801, 15 inches long, was taken at Biddefbrd 

 Pool, Maine. This distribution is even more puzzling than that of A. sphyrcena. 



ARGENTINA STRIATA, Goode and Bean, n. s. (Figure 62.) 



The height of the body is contained 7 times in its total length; the length of the head 

 3 times in total length. The eye is contained 2A times in the length of the head, and is 

 longer than the conical snout. Ventrals nearly median; their insertion under the penulti- 

 mate dorsal rays. Scales in the lateral line obliquely striate. Tongue with teeth. Origin 

 of the dorsal equidistant between snout and root of caudal. There appears to have been a 

 silvery, longitudinal band under the lateral line. 



Radial formula: I). 10; A. 11; P. 17; V. 14. 



The specimens studied were denuded of scales, but the impressions indicate that there 

 were 51 in the lateral line, 4 above and 4 below. The specimens (No. 43858, IT. S. N. M.) 

 were obtained by the Albatross from station 2402 in 28° 36' X. lat., 85° 33' 30" W. Ion., at 

 a depth of 111 fathoms. 



Argentina elongata, Hutton (Annals and Magazine of Natural History, in, 1870, 53. — 

 Voy. Challenger, xxn, 218), was obtained at Port Campbell, New Zealand.
