DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



there was sufficient evidence of its being a very distinct species from any of tin- flat tislics 

 known to inhabit the British Seas. Nevertheless, we find it in tlie ' Fishes of Great liritaiti 

 by P. Day (who seems to have followed Giglioli) relegated to the synonymy of RIkdiiIiks" 

 viegastoma, an error which, in 1883, was corrected by Vinciguerra, and in 1887 by Kolamba- 

 tovic, both of whom clearly pointed out the distinctive characters of theses two speciies." 



" Rhombus Bnscii may be recognized at the first glance by its enormous ej-es, which are 

 much larger than in Rhombus megastoma, as maybe seen from the following raeasuremeuts:

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

 are so conspicuons a feature in R. Bo.scii, although they may also disappear in specimens of 

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

 {GUnther). 



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

 Green, of several specimens off" the southwest coast of Ireland, at 150 and 313 fathoms 

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



Arnoglossus Grohmanni, Bonaparte (Pleuronectes Grohmanni, Vaillant, Exp. Sci. Trav. 

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

 form off the coast of Morocco in 112 and 120 metei'S, off" Spain in 10(5 meters, off Soudan 

 in 102 to 175 meters, and about the Cape 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 contained five and a half times in 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 interorbital space equals the vertical diameter of the 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 vcntrals, also, are small, but 

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

 anal terminate immediately iu front of the caudal. Scales of both sides ctenoid, more so 

 on the colored than on tlie l>lind side. (Joloratiou uniform gray (Giinther).

This species is distinguished by characters which bring it near to ISolcd vulgaris 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. Unfortunately only one specimen was obtained, olf the southwest coast 

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

 preservation (Giinfher.) 



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

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

 91 to 107 fathoms.
