"It is not my intention hero to redescribo the outward or hard parts— the exoskeletou— 

 of those species which have been described, but simply the iucladed soft parts of such as 

 have come into my possession and have not heretofore been given." 



"In my vols, i., ii., vi., vii., viii, and ix., taken from the Trans. Amer. Phil. Soc. and the 

 Journal of the Acad. Nat. Sci., I have published descriptions of the soft parts of ninety-one 

 species, which, with those herein described, will make two hundred and thirty -four."
