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

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

 dorsal. Seale.sininutolyspinigerous, almost smooth in young. Head scaleles.s, diaphanous. 



Radial (orniula: D. 10-12; A. 12; P. 14; V. 11; L. lat. 52. 



This form is abunditnt in shallow water in the Mediterranean and Adriatie, where it is 

 often taken by the fishermen. It is kiiowu also off Portugal and in the northeastern Atlan- 

 tic from Scotland to 01° and beyond. In Norwegian waters it occurs in the depths, Collett 

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

 another place. 



A. i^phynvna spawns in April in the Mediterranean. 



(xiinther considers A. decagon from llokitika, New Zealaml, to be the same form. 

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

 A. liuglossa, 0. & V., is also identical with A. .sphyrcpna.

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

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



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

 measurements given by Goode and l>ean, loc. cit.) 



This form occurs in Norway at depths of 100 fathoms and less. The first taken in North 

 America — the type of A. .si/rten.sium, Goode and Bean (U. S. N. M , No. 21624) — was found 

 iu the .stomach of a Phi/cis from Sable Island Bank, in 200 fathoms. In July, ISOl, a 

 specimen IS inches long (U. S. N. M., No. 43708) was caught by a boy with a hook and line 

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

 Pool, Maine. This distribution is even more puzzling than that of ^1. splnitmia. 



ARGENTINA STRIATA, Goode and Bean, u. 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 2.J times in the length of the head, and is 

 longer than the conical snout. Veutrals 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 hand undtn- the lateral line. 



Radial fornmla: D. 10; A. 11; P. 17; V. 14. 



The s])ecimens studied were denuded of scales, but the impressions indicate that there 

 were 51 iu the lateral line, 4 above and 4 below. The specimens (No. 4.>S5S, U. S. N. M.) 

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

 a depth of 111 fathoms. 



Arf/entina elonf/nta, Hutton (Annals and Magazine of Natural History, iii, 1879, 53. — 

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