in both species, which therefore ought to be removed from 
the genus Arnoglossus. 
In the British seas both species occur, but, so far as we 
know at present, 2. megastoma does not go the same depth as 
RL. Boscti, but extends further northwards. 
I subjoin a full description of Rhombus Boscit. 
D. 80-81. A. 63-65. L. lat. 85. 
The height of the 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 with a sub-semicircular 
curve above the pectoral fin. Lower jaw prominent; maxil- 
lary nearly one half of the length of the head. ‘he 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 the Common 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
