INVERTEBRATE FAUNA OF LABRADOR. 267 



cent hues ; the bright red spermaries and ovaries, the deep purple, red tentacles being in 

 striking contrast with the delicate tints of the spherosome. As noticed by Mr. A. Agassiz, 

 they are very difficult to keep for more than an hour or so in confinement. This species 

 was extremely abundant from the Straits of Belle Isle, where there was floating ice in the 

 last of June, to as far north as Hopedale in lat. 55° 30'. It was not commonly met with in 

 waters from which the ice had disappeared. It was not noticed by us during our residence 

 in the summer of 1860 at Salmon Bay. 



In harbors free from ice the Metiensia would keep out of view near the bottom ; but 

 as soon as the ice drifted in and choked up the harbor, myriads could be seen near the 

 surface, rising and falling between the ice-cakes, gracefully throwing out their tentacles, 

 which were nearly two feet in length, and suddenly withdrawing them when disturbed.
