hy Dr. Woodward as Limtpanis vancouverensis (Whiteaves) 

 and L. canadensis (VVhiteaves) there is this difficulty, that the 

 rostral part is defective, so that it is not clear why the species 

 should be referred to Linipanis rather than to Jasiis- It should 

 be noted that the generic names Screx Pfeffer, Amis 

 Ortmann, and Pucr Ortmann, were discarded from this 

 family by the last named author in 1S97 for very sufficient 

 reasons.

T. J. Parker instituted Jasus only as a subgenus, but subse- 

 cjuently claimed priority for it over Bate's Palinostus- Bate sub- 

 stituted Palinosytns for Palinostus on the ground that A. Milrie- 

 Edwards had employed Palinustus for the name of a new Scyl- 

 larid, distinct from Bate's Palinosytus and near to Palinurus.

Dr. Ortmann includes in the synonym the Chilian Palinurus

 St. Paul in the Indian Ocean, Heller, 1862, which Heller himself 

 had subsequently recognized as a young form of lalandii 

 (Novara Crustacea, p. 98), and the P. edivardsii, Hutton (Trans- 

 N.Z. Inst., 1875, p. 279), from New Zealand and Tasmania.
