Halyclystus auricula Clark. 



Very abundant on Chorda filium, at low water, August 14th, Anticosti, S. W. Point. Anti- 

 costi Expedition. 



Lucernaria quadrieornis Mull. 



Caribou Island, ten fathoms, sand. These two species of Eleutherocarpidae have been 

 submitted to Professor H. J. Clark for identification. 



Manama auricula Clark, 



Lucernaria auricula Fabr. (non Mull.) 



Not common ; did not differ from specimens received from the Scandinavian Naturalists. 



Trachynema digitale A. Agass. 

 Medusa digitalis Fabr. Faun. Gronl. 



Specimens, agreeing well with Mr. A. Agassiz's figures and description, and of a beautiful 

 sherry tint, were dredged in fifteen fathoms, rocky bottom, near "Strawberry Harbor," and 

 at another point on the coast, southward. 



Cyanea arctica Per. et Lesson. 



This species is most commonly observed in the Straits of Belle Isle. 



Aurelia flavidula Per. et Lesson. 



Found abundantly in the Straits of Belle Isle, and in retired bays. 



Idyia roseola Agass. Contr. Nat. Hist. U. S. 1860. 



A very abundant form, and occurring along the coast from Cape Webuc (Harrison) to 

 Salmon Bay in the Straits of Belle Isle, and not differing apparently from specimens ob- 

 served on the coast of Maine. At Indian Tickle a specimen six inches long was observed. 

 Another specimen was found swimming with its body contracted into the form of a very 

 flattened, oblate sphere, and hence was scarcely recognizable at first sight. The first week 

 in August great numbers of fragments of these animals were observed floating near the 

 surface together with still more abundant wrecks of 3fcrtensia, adding greatly to the phos- 

 phorescence of the sea, as specimens obtained in the night testified.
