scription of the genus Lafystius, (Tidskr. 1 ser. vol. iv. 

 p. 156,) from which it differs chiefly in the form of the 

 second pair of legs, which, in the latter genus, are de- 

 scribed as having the finger sublaminar, with the apex 

 somewhat setose, we presume, as in Callisoma. Their 

 habits also appear to be similar. 



This genus is named in compliment to the distin- 

 guished author of the " Monograph on the Cirripedia," 

 one of the most complete works of the kind ever pub- 

 lished.
