DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



there was sutticieiit evidence of its being a very distinct si)ecics from any of tlie flat tislies 

 known to inhabit the Eritisli Seas. Nevertheless, we lind it in the 'Fishes of Great liritaiii 

 by F. Day (who seems to have followed Giglioli) relegated to the synonymy of Rhombus' 

 mctiastoma, an error which, in 1SS3, was corrected by Vinciguerra, and in 18S7 by Kolamba- 

 tovic, both of whom clearly pointed out the distinctive characters of these two species.'' 



" Rhombus Boscii may be recognized at the first glance by its enormous eyes, which are 

 much larger than iu RhoiiiJtits megastoma, as maybe seen from the following measurements: 



Total length..

Length of osseous orbit

"Rhombus megastoma never has the large black spots on the dorsal and anal fins which 

 are so conspicuous a feature iu R. Boscii, although they may also disappear in specimens of 

 the latter species if they have been allowed to get stale before they are placed in spirits" 

 {(riinther). 



This species was added to the British fauna by the discovery iu 1889 by the Eev. Mr. 

 Green, of several specimens off the southwest coast of Ireland, at l.JO and 315 fathoms 

 (Giinther, Ann. and Mag. Nat. Hist., December, 1889, 418). 



Arnoylossus Grohmauni, Bonaiiarte (Plcurottectcs Grohmanni, Vaillant, Exp. Sci. Trav. 

 et Tal., 188). The French explorers obtained si>ecimeus of this well-known Mediterranean 

 form oft' the coast of Morocco iu 112 and 120 meters, off Spain in 106 meters, off Soudan 

 in 102 to 175 meters, and about the Cajie Verde Islands in 75 to 90 meters.

This species is very elongate, its greatest width being one-third of the total length 

 (without caudal); the length of the head is coutained five and a half times iu the total 

 length. The shape of the head resembles very much that of the common sole. The eyes 

 are of medium size, about as long as the snout and one-fifth of the length of the head; the 

 width of the iiiterorbital space equals the vertical diameter of tlie eye. None of the nos- 

 trils dilated, that in front of the lower eye being prolonged into a short tube; the vertical 

 fins are rather low and covered with scales. The right pectoral very small, about as long 

 as the eye; the left pectoral is reduced to a minute ray. The veiitrals, also, are small, but 

 the extremities of their middle rays e.Kteud backwards to the anal fin. The dorsal and 

 anal terminate immediately iu front of the caudal. S(;ales of both sides ctenoid, more so 

 on the colored than on the blind side. Coloration uniform gray {Giinther). 



Eadial formula: D. 81 ; A. Cm; P. dextr. 5; P. sin. 1; L. hit. 144. 



This species is distinguished by characters which bring it near to *S'o,'tY( rulgaris as well 

 as to Solea variegata. From the former it is separated by the rudimentary structure of its 

 pectoral fins, from the latter by the number of its fin rays, by its much smaller scales, and 

 by its coloration. Uufortuuately only one specimen was obtained, off the southwest coast 

 of Ireland, nearly 6 inches long, at a depth of 150 fathoms. It is in a perfect state of 

 l>reservation {Giinther.) 



Solea timbralites, Alcock (Journ. Asiatic Soc. of Bengal, LXiii, Part ii, No. 2, p. 17, 

 PL VII, fig. 3), was obtained by the Investigator in the Bay of Bengal, stations 169 and 170, 

 91 to 107 fathoms.
