Verrill confuses this species with C. flexuosa 
Hincks, and includes both species under

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.

“Vineyard Sound, northward; .... off Gay 
Head, 8 to 10 fathoms, on ascidians.” — Verrill. 
Nutting thinks it likely that this is the same 
species as Eucope pyriformis A. Agassiz.

Dredged by the Survey throughout Vineyard 
Sound, and occasionally in the lower half of 
Buzzards Bay, occurring at 1 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 medusae occur during the 
summer.
