Common among weeds everywhere. The above re- 

 erences will show some of the variations to which the 

 rostrum is subject. 



We know of no other Crustacean so remarkable for that 

 striking variability in colouring which has long been remarked 

 in Hippolyte varians, and which indeed gave it its most 

 appropriate specific name. Messrs. Keeble and Gamble 

 have recently studied with great care the causes of and the 

 means by which these various colours are produced, and the 

 result of their investigations is of so much importance, that 

 it cannot but lead to great modification as to the views 

 generally held with respect to coloration. These papers

 Hippolyte varians," Proc. Royal Soc. vol. Ixv. 1900, p. 461;
