1 Avould .strongly adviso tlio student of Fossil Cyclostomata to com- 

 l)ave tlio species named, if in Ids power to do so, or contrast at least 

 the lists given iu this report from Hincks, Busk, Hagenow, and 

 Ileuss. It will bo seen what diflerent estimates arc given of Zoari;d 

 characters by the diflerent authors. The multiplicaticm of species is nn- 

 iivoidable if we take into consideration habit only. In Smitt's list given 

 above, the author certainly deserves the thanks of workers for his 

 endeavour to combine leading facial characters in his simple Family 

 arrangements, and I think I may venture to say that Smitt's Generic; 

 combination embraces all, or nearly all, the structural features that may 

 be found in the study of this peculiar sub-order of the Polyzoa. It may 

 be, however, quite possible to give simplicity of arrangement too wide a 

 scope. (See Hincks and Busk on the Cyclostomata). 



Dr. August Goldfuss, ' Petrefacta Gcrmanioe,' 1820. 



The ' Zoophytorum Reliqnia) ' of Goldfuss were classed under forty-five 

 genera, and the genera Escuara, Cellepora, Retepoka, aud Ceriopoua —
