of the wharf at New Bedford. Collected by 



Mr. Vinal Edwards." Nutting.

Verrill confuses this species with C. flexuosa 

 Hincks, and includes both species under 

 C. flexuosa.

Hydroids common and of general distribution in 

 shallow waters locally, being found on rocks, 

 piles, or seaweed. In the Survey dredging re- 

 corded only from Fish Hawk stations 7678*, 

 7680*, and 7707*. Medusae taken in abundance 

 occurring from July to September.

 Mayer, 1910, p. 249 (Obelia geniculata). 



Hydroids reported as abundant in local waters, 

 on Fucus, etc.; medusae likewise common, 

 being referred to by A. Agassiz as "by far the 

 most common of our jellyfishes." According 

 to this writer, the medusae occur from March 

 to November.

Dredged by the Survey throughout Vineyard 

 Sound, and occasionally in the lower half of 

 Buzzards Bay, occurring at i to 16 fathoms, on 

 various bottoms, generally growing on Lamin- 

 aria or other seaweeds; taken most abundantly 

 at the western end of the Sound. This species 

 is likewise common on piles and floating tim- 

 bers, and is occasionally found growing in 

 profusion on other animals, such as Lepas, the 

 sargasso crabs, and even the sea horse (Hip- 

 pocampus). The medusas occur during the 

 summer.
