in both species, wliicli therefore ought to be removed from 

 the genus Arnoglossus. 



In the British seas both species occur, but, so far as we 

 know at present, R. megastoma does not go the same depth as 

 R. Boscri, but extends further northwards. 



I subjoin a full description of Rhombus Boscii. 



D. 80-81. A. Q?j-Q5. L. iat. 85. 



The height of tlie body is two fifths of the total length 

 (without caudal), the length of the head nearly one third ; 

 scales rather small, with the posterior margin ciliated, trun- 

 cated or rounded, covering nearly the whole head, the inter- 

 orbital space and the maxillary included ; interorbital space 

 extremely narrow ; the diameter of the eye is one third of the 

 length of the head. Lateral line witii a sub-semicircular 

 curve above the pectoral fin. Lower jaw prominent; maxil- 

 lary nearly one half of the length of the head. The teeth in 

 the jaws form narrow bands ; vomerine teeth in small number 

 (two or three) implanted somewhat behind the front margin 

 of the vomer. The lower eye a little in advance of the upper. 

 The dorsal fin terminates at a distance from the caudal which 

 is somewhat less than the depth of the free portion of the 

 tail ; its longest rays are at the commencement of the pos- 

 terior third of the fin, where they are two fifths of the length 

 of the head, and rather shorter than the pectoral. No spine 

 before the anal. Body very light coloured, without spots ; 

 two large rounded deep black spots occupy the posterior 

 portion of the dorsal and anal fins. 



The largest specimen obtained is 14 inches long, the 

 smallest about half that size.

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 theCommon Sole. The 

 eyes areof 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 nostrils 

 dilated, that in front of the lower eye being prolonged into a 

 short tube ; the vertical fins are rather low and covered with
