at any depth, but generally present in the deepest water tested, 
and then frequently found in considerable numbers when no 
other flatfish were taken. The largest specimen’ taken 
measured 1214 inches. These fish are peculiarly transparent, 
flesh white and full of fine bones.”’ 
Two other species of the genus have been described, namely :— 
C. boops Hector and C. hectoris Ginther, but they were not 
taken by the trawler. They were included in the collections of 
the Challenger Expedition, made in deep water, beyond the 
reach of payable trawling; moreover they are doubtless equally 
inedible with the Megrim. 
RHOMBOSOLEA Gunther, 1862. 
Stations 7, 8, 10, 16, 32, 35, 40, 44, 45, 46, 51,52, 61, 72, 
76, 77, 96. 
Owing to the unsatisfactory condition of our knowledge of 
the members of this genus it was not possible to identify the 
species as they were brought aboard, but an examination of the 
specimens preserved indicates that but two species were taken, 
namely, R. plebeia and R. millari. The specific stations at which 
each was secured cannot however be given. 
A study of the literature and available specimens indicates 
that there are four species of Rhombosolea at present described 
from our waters, one of which, R. millari, is herein named for 
the first time. The following synopsis indicates their distin- 
oulshing characters :— 
a. Body deep, 1.4 or more in the length, vertical 
fins elevated, shape rhomboidal, colour grey 
clouded aye ae ae re 
aa. Body lower, 1.7 or less in the length, shape 
ovate. 
b. Anterior profiles straight, or nearly so, eyes 
large. 
ec. Snout produced over the mouth, ventral 
inserted below the eye, colour green 
above, with dark blotches, pure white 
below Ms Bh on ue 
ee, Snout normal, ventral inserted behind 
the eye, colour grey, clouded; yellow 
below, uniform or with scattered black 
spots + ah ur millari. 
bb. Anterior profiles rounded, eyes small, 
colour olive with red spots, dark beneath retiaria. 
plebeia. 
tapirina.
