so the total record is now brought up to 87 species and 1 

 variety. 



I have arranged these in the following table so as to show 

 their distribution in the district, as has been done in pre- 

 vious reports on other groups, so that here I need only 

 mention those that seem to call for special remark. 



In the first place, we have found several that are rare : — 

 two species Hydranthea margarica, (found growing on 

 Flustra foliacea, the habitat which Hincks gives), and 

 Gampanulariafragilis, have only been found at Ilfracombe 

 before; two others Obelia plicata and Gonothyrcea hyalina 

 are only known from the Shetland Islands ; Galycella 

 pigmoea, only at Tynemouth, and Gonothyrcea gracilis, 

 only at Connemara ; while several have only been found 

 before in the South, such &&Bougainvilleamuscus (Torquay) 

 Gampanularia raridentata (Swanage, Brixham, Torquay), 

 Plumularia setacea (Cornwall), and Gampanularia cali- 

 culata (Ramsgate, Cork;. 



Secondly, the following species have presented some 

 noteworthy points of structure, or have shown some 

 previously unrecorded character : — 



Obelia geniculata, Linnaeus. 



Specimens of this luxuriantly branched (Hincks says 

 they are sometimes sparingly branched) were found lately 

 at the Isle of Man. The branches, or in their place, two 

 extra pedicels, bearing calycles, rise from the axils of the 

 ordinary pedicels. Tendrils like those on Gampanularia 

 angulata were fairly common on these specimens, as I have 

 also seen them on Campanularia flexuosa and Obelia 

 plicata. 



Gonothyrcea hyalina, Hincks (PL IX, fig. 1). 



This species has not been recorded by us until now, as 

 although I have examined a good many specimens of it 

 I have always wanted to see more before saying that I
