that they are seasonal as many hydroids are, and that his previous col- 

 lecting had never been at a suitable time. The date in which I found these 

 fine colonies was practically the same as the date he mentions (Aug. 10), 

 two years previous. 



EuDENDRiuM CARNEUM Clarke. 



This species has been reported from the Woods Hole region several times 

 but all such reports agree in stating that it Mas rare. Apparently it has 

 now become well established in the region as last season it was quite plen- 

 tiful even on the piles of the U. S. B. F. wharf, where it appeared in 

 close proximity to specimens of Eudendrium ramosum, the species of Eu- 

 dendrium that has been predominant for some time. At Beaufort the two 

 species were found growing side by side in many localities in the same 

 way. It will be interesting to find out if they will continue to live side 

 by side, or if the one will crowd the other out. They are both rather lusty 

 species and would appear to have almost equal chances to survive. At 

 Woods Hole evidently E. carneum is the invader. It remains to be seen 

 how extensive the invasion may be. 



Eudendrium vaginatum Allman.^ 



I believe this species has not been reported from the Atlantic Coast of 

 North America, though it is not unnatural that it should appear, as it 

 has been reported from Europe and from the west coast of North America. 

 Many species that have been so reported are found on the west side of 

 the Atlantic. 



Fine specimens of male colonies were found at Basin Cove, South Harps- 

 well, at the old tide mill site. Other specimens without gonophores were 

 obtained in some material dredged in Quicks Hole at a depth of about 

 10 fathoms. The extensive annulation and the characteristic shape of the 

 hydranth were sufficient for identification. 



TuBULARiA CROCEA (Agassiz) . 



Tubularia crocea is most plentiful at Woods Hole, at Vineyard Haven 

 and at other places in the vicinity, where at the end of June and early 

 in July it is in a flourishing condition, with the actinules still contained 

 in the bud attached to the hydranth body, or already liberated so that the 

 new colony is begun. Soon after this, the * ' heads ' ' are all lost and nothing 

 remains but the twisted stalks of the colonies, with possibly many young 

 colonies, just starting to grow, attached to various points on the hydrorhiza 

 or even on the lower part of the stems. 



When I reached South Harpswell, after the middle of August, no such 

 degeneration was apparent in the specimens in that locality. The colonies
