"Off Gay Head, 8 to 20 fathoms." Verrill. 

 Abundant and of general distribution through- 

 out Vineyard Sound and Buzzards Bay, being 

 one of the few hydroids dredged with great 

 frequency in the latter; taken in 2 to 19 

 fathoms, on every sort of bottom. Survey. 

 Likewise abundant on piles and frequent in 

 shallower waters than those reached by the 

 dredge.

Concerning reproduction Bumpus records: "Col- 

 onies of Eudendrium, probably E. ramosum, 

 were taken in a very imperfect condition June 

 17 [1908], apparently just beginning from old 

 stolons * * * The earliest signs of develop- 

 ment of eggs occurred during the first week 

 of July. The latest were recorded by Dr. 

 Murbach, on September 15." 



After speaking of the slight mention made of 

 Eudendrium ramosum in the earlier accounts 

 of our local fauna, Hargitt comments: "Can 

 it be possible that this species is a recent 

 comer into this region, or has it become 

 more prolific and abundant of recent years, 

 or was its earlier presence simply overlooked 

 by naturalists?" 



Eudendrium dispar Agassiz. [Chart 17.] 

 A. Agassiz, 1865, p. 159; Verrill and Smith, 1873, 

 p. 734, 408; Hargitt, 1901, p. 309; 1008, p. 96; 

 Nutting, 1901, p. 332. 



Naushon. A. Agassiz. Vineyard Sound. Ver- 

 rill. Apparently no local specimens were 

 assigned to this species by Nutting. Speci- 

 mens thus identified by Dr. Hargitt were 

 dredged rather frequently by the survey in 

 Vineyard Sound, almost exclusively in the 

 western half, in 8 to 19 fathoms, for the most 

 part on bottoms of sand and gravel. Taken 

 also at Great Round Shoal, off Nantucket, 

 July 23, 1908*. There are no Survey records 

 for Buzzards Bay. Hargitt 's statements (1908, 

 p. 96, 97) to the effect that this species "seems 

 to be more common in Buzzards Bay, ' ' and that 

 it "has not been taken on the average once 

 per year during this period [i. e., 15 years]" 

 were based upon a misunderstanding as to the 

 source of certain specimens which were 

 examined by him.
