Rev. T. Hincks has valuable notes on the classification of Polyzoa. 
Lang has a very interesting account of the anatomy and affinities of 
Cephalodiscus. Cori writes on the anatomy and development of the 
nephridia in Polyzoa , and Davenport and Prouho have important 
embryological papers. In systematic work a great deal has been done.
