might be thought that if Jawea were present in the Clyde, specimens 
occasionally ought to be taken in the trawl or dredge, yet none have ever 
been observed. ‘This, however, does not militate against the supposition 
that this crustacean occurs within the Clyde estuary, for its habitat may 
be about rocky ground, where neither trawl nor dredge could be used, but 
which would offer no obstruction to gurnards in their search for food. 
Moreover, it was shown in my paper in Part III. of the Seventeenth 
Annual Report (1899) that at Naples, though the iarval forms of 
Calliaxis (Jaxea) are met with amongst the surface fauna, the adult has 
only been found once in 25 years. But whatever be the opinion concern- 
ing the habitat of this apparently rare species—that is, “rare” as regards 
its adult form—the fact that fragments of adults were found in the 
stomachs of gurnards caught in the vicinity of Ailsa Craig is in itself of 
much interest to students of the British crustacea. The fragments referred 
to above are now in tke Laboratory at Bay of Nigg. 
After the preceding notes had been sent to the printer, Mr. Pearcey 
kindly forwarded the posterior portion of another specimen of Jawzea, 
which he had obtained in the stomach of a witch sole (Plewronectes 
cynoglossus, L.) captured at Station VIII., Firth of Clyde, on the 20th of 
November last (1899). Station VIII. is about five miles west by south 
of Ailsa Craig. (This specimen is in our collection at Bay of Nigg with 
the others previously referred to.)
