most nearly related to the recent deep-water Lepidopleiirus. Barrande's Triopus 

 seems however to have escaped his observation. The system of Pilsbry is adopted 

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

 part than No. 56 (published a year ago) might have reached Dr. Simroth. A brief 

 general review of the Amphineura closes the part in which, inter alia, he 

 reviews their relationship with the Annelids and Turbellarians. Printers' errors 

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

 " Aplacop/iora," otherwise the drawings are very clear and distinct. — E. R. S.
