 seems however to have escaj^ed his observation. The system of Pilsbry is adopted 

 practically in its entirety, though we cannot help thinking that some 'more recent

 general review of the Ainpliineitra closes the jiart in which, inter alia, he 

 reviews their relationship with the Annelids and Turl^ellarians. Printers' errors 

 are rather numerous, and some of the plates of Chitons are lettered as 

 '■' Aplaiophom,'" otherwise the drawings are very clear and distinct. —E. K. S.
