Bougainvillia superciliaris Ag. Fig. 90. 
(Cont. Nat. Hist. U. S., IV, p. 289. ) 
Tropliosome.— Colony attaining a height of about 2 inches. Stem not fascicled, irregularly 
branched, branches and branchlets often annulated proximally. Hydrantlis with very inconspicuous 
proboscis and 15 to 20 rigidly disposed tentacles. 
Gonosome .— Gonophores borne mostly on the ultimate branches. Mature medusae with a very 
broad and heavy proboscis and much ramified mouth tentacles. Each cluster of marginal tentacles 
with a large sense-bulb at its base. 
Color . — Colony light brown with a greenish tinge. Hydranth body with a suggestion of rose 
color. Medusae with a pale-yellow proboscis tinged with red at the end. Sense bodies orange red 
surrounded with yellow. 
Distribution. — Newport, It. I., attached to fucus and shells. Woods Hole. I have not seen the 
tropliosome of this species and have culled the description from that of Dr. Alexander Agassiz. The 
medusa was taken by me at Woods Hole on August 11, 1899. 
Bougainvillia carolinensis (McCr. ). Fig. 5. 
{Uippoef ene carolinensis McCrady. Proc. Elliott Soc., vol. I, No. 1, p. 164. ) 
Tropliosome . — Colony attaining a height of 12 inches, but usually 3 to 6 inches, and branching 
much as in the preceding species. Hydrantlis growing on both main stem and branches, with a long, 
prominent, very flexible proboscis, which may be a lengthened cone, or may be rolled back until it 
assumes a saucer-like shape; tentacles not more than 12 in specimens examined. 
Gonosome . — Gonophores borne on both main stem and branches, often in clusters. Mature 
medusa; much like the last, but with a short and narrow proboscis. 
Color . — Colony light brown with greenish tinge, hydranth body with reddish tinge. Medusae 
with brick-red proboscis and sense-bulbs red surrounded by green and yellow. Eye-spots jet black. 
Distribution . — Growing on the piles of the U. S. Fish Commission’s dock at Woods Hole, and 
common in the vicinity. It. is often found attached to fucus and floating timber.
