POST-LARVAL TELEOSTEANS COLLECTED NEAR PLYMOUTH. 249 
PEDICULATI. 
Lophius piscatorius L. 
One specimen of an early stage, 6-2 mm. long was found in Haul LXIT., 
taken near the bottom 7 miles west of Rame Head on July 16th, 1914. 
A figure of this specimen drawn by Mrs. Sexton is reproduced as Fig. 8. 
The great resemblance of this figure with Emery’s figure, which is repro- 
duced by Ehrenbaum in Nordisches Plankton, p. 303, Fig. 108, b, and 
ascribed by both authors to Macrurus, may be pointed out. It seems to 
me very probable that that figure should really be assigned to Lophius. 
The larva of Lophius piscatorius is figured by Danois (1918, p. 164, 
Fig. 319). Ehrenbaum (1905-9) reproduces Agassiz and Whitman’s 
figures of American specimens. 
SUMMARY. 
Table XLV. is perhaps of interest, as showing the composition of the 
catch obtained with the young-fish trawl at different times of the year. 
It has been obtained by combining certain groups of hauls made in 1914 
in the offshore waters outside Plymouth, all of them being beyond 
the 20-fathom line. As far as the conditions are concerned therefore the 
different groups are fairly comparable. The figure given for each species 
is the average number of specimens per haul for the group. It will be 
seen that after June the number of species present as well as the average 
number per haul are both very much reduced.
