some British PoJyzoa. 211 



Polyzoon has been dredged by me in 80-170 futlioms off 

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

 Mr. C Peach also sent me a specimen taken by him off 

 Wick, 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 notliing to add to the 

 description wiiich has already been given. I have pro- 

 visionally placed the species in the genus Phylactella, as, 

 perhaps, it comes nearer to P. coUaris than to any other 

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

 genus, P. labrosa. The small size of the zooecia may be 

 judged by fig. 2, which represents tiie outline of a zoariuin 

 which will contain forty to fil'ty zooecia.
