CYCLOPTERID^. 



Cyclopterus lumpus L. Cyclogaster montagui Donov. 

 Cyclofterus lumpus L. 



Only one specimen of the lumpsiicker is recorded. It was taken ni 

 the Zostera bed of Cawsand Bay in a mid water haul on 24:th September, 

 1913. The total length was 18 mm, 



Cyclogaster montagui Donov. 

 Post-larv8e of this species occurred most frequently in June, at lengths 

 ranging from 3 to 7 -07 mm. The capture of two specimens 5-6 and 6 -7 mm. 

 in length in August and September, in bottom hauls, seems to suggest 

 a long post-larval life. In these, the sucker was well developed in front 

 of the abdomen, as in Ehrenbaum's Fig. C, " Nordisches Plankton," 

 Vol. I. 



TRIGLID^E. 

 Trigla gurnardus L. T. hirundo Bl. T. cuculus L. T. lineata (Ray). 

 Our knowledge of post-larval gurnards is extremely limited. Only 

 T. gurnardus and T. hirundo, two of the five species that occur at 

 Plymouth, are known with any degree of certainty. Trigla gurnardus 

 is well represented in the collection, and appears to be the com- 

 monest post-larval form, T. hirundo has been partially worked out 

 by Emery* for the Mediterranean, and his descriptions of the post-
