I have recently found among material put by for further 

 examination a little box which contained three small pieces of 

 the above Polyzoon, and labelled Guernsey. I cannot recall 

 to mind whether I procured these specimens myself at 

 Guernsey in 1865 or whether they were given to me. 



Other specimens are in my collection from Naples, where 

 I found it in 1887 to be abundant, and from the Adriatic, 

 given to me by my late friend Professor Heller under his 

 name " Metnbrampora bifoveolata"
