BRITISH SPONGES NOT REFERRED TO IN THE 

 FOREGOING WORK BY DR. BOWERBANK. 



A. CALCAREOUS SPONGES OF ERNST HAECKEL. 



HAECKEL, in his Monograph, ' Die Kalkschwamme,' 

 enumerates and describes the following calcareous 

 sponges as members of the British Fauna. Of course 

 the generic names which he employs cannot in many 

 instances be retained by biologists, but must give 

 place to genera of earlier date. The localities appended 

 are those from which Haeckel has examined specimens.
