different from that of the sessile polyp as the butterfly from the 

 caterpillar. Others are not known to have this double kind of 

 existence, but produce ova or little locomotive ovoid bodies which 

 lay the foundation of new groups. 



To a visitor to the sea side, provided with a microscope, these 

 creatures form a very agreeable study. When taken up alive 

 and placed in a vessel of sea water, the extension and retraction 

 of their beautiful transparent bodies and crowns of tentacles 

 looking like beads strung on a spider's thread, present a spectacle 

 strikingly illustrative of the amount of life that exists hidden 

 under plant forms in the sea. When a mere boy, I have spent 

 many holiday afternoons in searching for these creatures that I 

 might enjoy this curious spectacle, and I still treasure many rough 

 sketches of their forms and structures made to perpetuate the 

 wonders which they disclosed under the microscope. I am sorry 

 that in the present notes I can refer not to the living animals but 

 only to dried specimens. 



Family Tubulariadce. 



1. Eudendrium ramosum. — The genus Eudendrium has tubular 

 branches, at the ends of which are pretty reddish polyps, not re- 

 tractile, and with one or two rows of tentacles. In Miss Carey's 

 collection is a specimen not distinguishable from the species above 

 named, which is a common British form. I have not met with it 

 elsewhere. 



2. Tubularia indivisa. — In the genus Tubularia the cells are 

 simple horny tubes, with beautiful flesh-colored polyps, not re- 

 tractile, and with two rows of tentacles. The T. indivisa occurs 

 of large size at Sable Island, from which I have a specimen col- 

 lected by Mr. Willis, of Halifax. It was attached to a sponge, 

 Stimpson notes it as occurring at Grand Man an. 



3. Tubularia larynx. — This pretty little species I found alive 

 in great numbers at Gaspe, and covered with its little bead-like 

 reproductive buds. The body is flask-like, of a red color, and 

 covered with short tentacles At the base of the body is a second 

 series of larger and lighter colored tentacles, and immediately above 

 these the little gems are attached like flower-buds fastened by 

 their smaller ends to the body. 



, 4. Tubularia . — Another small species, about the size 



of T. larynx, but with a simple and very flexible tube, occurs in
