I thus, for the present, conclude my report on the British species of 

 Carboniferous Polyzoa. It would have been comparatively easy for me 

 to have made it longer — it would have been difEcult indeed to have made 

 it shorter. To the Palfeontologist the study of the Pateozoic Polyzoa 

 opens up many very important biological details, for the connection of 

 the Polyzoa with the Graptolites is a question that must be dealt with 

 in detail; and the relationship of the Pateozoic to all other Polyzoa must 

 be grappled with intelligently and dispassionately; and for this pur^Dose 

 members of the Association could help either myself or others by furnish- 

 ing materials for the study.
