21. Lysianax ceratinus, Walker. 



Lysicma.v ceratinns, A. 0. Walker, " Third Report on Higher Crus- 

 tacea," Fauna of Liverpool Bay, vol. iii. p. 200, pi. x. figs. 1-8. 



Since the date of this publication the species has been 

 frequently named in Mr. Walker's papers as Lysianax longi- 

 cornis (Lucas), which, however, was an erroneous assignment 

 of the form, as he has subsequently stated. I have consider- 

 able doubts as to the specific distinction of this form from 

 L. septentri07ialis, since specimens occur apparently inter- 

 mediate with only a small spine point on the hinder margin of 

 the third segment of the metasome, instead of the large 

 upturned process of typical L. septentn'onalis. 



Hah. This seems to be a much more abundant form on our 

 coasts than L. septentrionalis. Isle of Skye ; Firth of Clyde ; 

 Berwick-on-Tweed ; Plvmouth ; Guernsey ; Strangford
