some British Polyzoa. 2 1 1 



Polyzoon lias been dredged by me in 80-170 fathoms off 

 Shetland and also in deep water in Bergen Fiord. Tlie late 

 Mi: C. Peacii also sent me a speeimen taken by him off 

 AVick, and it was also procured by the 'Porcupine' Expe- 

 dition of 1869. 



As the species has not been figured, it is illustrated here 

 in the annexed woodcut. I have nothing to add to the 

 description which has already been given. I have pro- 

 visionally placed the species in the genus Phylactella, as, 

 pt'rha))s, it comes nearer to P. collaris than to any other 

 form ; but it has little in common with the type of that 

 genus, P. lahrosa. The small size of the zocecia may be 

 judged by fig. 2, which represents the outline of a zoarium 

 which will contain forty to fil'ty zooecia.
