CRUSTACEA OF NORTHUMBERLAND AND DURHAM 405 



Two specimens of this species were found by A. Hancock 

 on as many examples of Eolis rufibranchialis from Whitley 

 (see Alder and Hancock, Nudibranchiate Mollusca, p. 26), 

 and others from Dofo coroiiafa from rock pools at CuUercoats 

 by H. T. Mennell and A. Hancock. 



Dr. Thomas Scott has described a parasite of Lo/na/wh/s 

 geiiei under the name Lotnanoticola insolens, which is very 

 closely allied to, if not the same as the foregoing (Ann. and 

 Mag. Nat. Hist., ser. 6, vol. xvi., 1895, p. 360, pi. xvii., 

 figs. I, 2). N.

We cannot doubt that Miss Bainbridge's species is C. 

 annulatus of Olsson. We (A. M. N.) have cotypes of that 

 species in our collection, and also cotypes of Chondracanthus 

 pallidus received from Prof. E. Van Beneden, which seems to 

 be the same species ; but at this moment we fail to call to 

 mind where the description of that author is to be found. N.
