 The I'odd of this species is coin|)ose{l of (iainiiiai'ids and 

 othei' small c rustaeeaiis, and siikiII shelUisli. It is of 

 no importauce to the fisheniian. Its goograijliical range 

 extends from Norwegian Kinmark to the southern coasts 

 of I'jiiglaiid and Ireland". ( )n the west coast of Sweden 

 it goes as far as tlie Sound, where; it was first dis- 

 covered off Landskrona 1)\' Sciiaokhsthom. < )n the 



liM'k. in the (ireat Belt, according to Wixtmi-.i;, two 

 specimens ahoiit 100 mm. long have been taken in I'^el- 

 pots. it has also lieen found ofl' Mocn and in the 

 Little l>elt; but in the Baltic itself it is unknown. 

 Whether it occurs on the coast of Greenland, seems ac- 

 cording to the results of LOtkkn's investigations'', to be 

 a matter of donbt; but according to doitOAN and Ctii.- 

 liKKi' it occurs on the American side of the Atlantic,

side it has also been found fairl\- often off Helle- ' on the coast of Massachusetts.
