NEW ENGLAND HYDROIDS 43 



were as fresh as the Woods Hole colonies were iu June. I have heard it 

 stated that the Maine forms do not lose their ' ' heads ' ' during the year, 

 or at least that whole colonies do not appear to degenerate at the same 

 time. If this is true, it would be an interesting point to investigate the 

 cause of the difference. 



Campanularia angulata Hi neks. 



This species has been reported from Woods Hole and it appears to be 

 widely distributed in the region. No specimens were found that were not 

 attached to eelgrass, but some may be found almost anywhere in the vi- 

 cinity where eelgrass grows. The best specimens found last summer were 

 growing in Little Harbor. These bore gonophores on the stolon, corre- 

 sponding exactly with those described and figured by Hincks.* 



Some specimens obtained at Wareham on Aug. 7 were provided with 

 long terminal tendrils, like those figured by Hineks. This is probably a 

 seasonal conditions, as many other species, e.g. Obelia commissuraUs, become 

 attenuated and give out tendrils after the generative products have been 

 liberated. The tendrils of C. angulata are broader and more ribbon-like 

 than those of 0. commissuralis and other eampanularian forms. 



Campanularlv calceolifera Huwks. 



Specimens of this species were found at Basin Cove, South Harpswell, 

 at the old tide mill site. This is the first time this species has been ob- 

 served or recorded in the Casco Bay region, or at any point north of Cape 

 Cod on the west side of the Atlantic. As it was first described in Britain, 

 it probably came across the ocean by way of the Arctic regions; hence in 

 getting to Woods Hole, where the species is plentiful, it must have passed 

 Casco Bay, but up until this time it has been missed by collectors. The 

 colonies presented no features that are not found in typical forms. 



! Campanularla. raridentata Alder. 



Verrill, in his Checklist,'''> gives this species with an interrogation mark, 

 but I have not seen any references to it in any other of his papers, or in 

 any other West Atlantic Coast papers, for that matter; at any rate, I 

 think it has not been reported from the Woods Hole region. Some excel- 

 lent specimens, the best I have seen, were obtained by dredging about half 

 way between Knobska Point and Falmouth Heights in five fathoms of 

 water. They were growing on a piece of dead t^\ig. Though I have found 

 several of these specimens on the Pacific Coast and at Beaufort on the 

 Atlantic Coast, I have not been able to find any gonosome, hence the gen- 

 eric name is still only provisional.
