DESCRIPTIONS OF SPECIES. 



The attention of the reader is called to the following notes of

 those of alcoholic specimens, and must naturally differ more or less 

 from those of living or fresh examples, but no notes on the latter 

 were given to the writer, and probably none were made. 



Except when but one specimen was obtained the descriptions and 

 anatomical figures must be understood as composites based on the 

 study of different individuals, since it is only rarely that all the 

 important details can be distinguished in one and the same individual 

 owing to the contracted and fragile condition of the delicate struc- 

 tures and organs. Type-specimens have been designated for the new 

 species. In order to avoid any possible misunderstanding it may be 

 worth while to state that where specimens have been referred to 

 species previously described, the descriptions and figures here given 

 have in no case been based partly on the descriptions of the other 

 authors, and partly on the Albatross specimens, but wholly on the 

 latter.
