The Genus Cheraphilus, as limited by Kinahan, is not 

 co-extensive with the Ponlophilus of Leach and Sars, and 

 has not a single character common to all the species to 

 separate it from Crangon as restricted by him. Neither 

 does the fact that Dr. Leach abandoned his genus Ponlo- 

 philus and the subsequent use of that name by Risso and 

 Brandt for certain Pandali affect the case in the least, as 

 regards the proposed name, which has been adopted by 

 Miers (Ann. and Mag. Nat. Hist., 1877, IV, xix, p. 133). 

 I accept the genus Pontophilus as limited by Sars (For- 

 haudl. Videusk. Selsk. i Christiania, 1861, p. 183).
