in 1869; and oflF Cap des Rosiers, in 38 fathoms, in 1871. Some of the 

 specimens from these localities were identified with this species by the 

 writer, and others, quite independently, by the Rev. Canon Norman.

Very abundant throughout the Gulf of St. Lawrence, often associated 

 with Myriozoum subgracile, Porella (Celleporaria) surcularis, Porella 

 elegantula, &c. It was first recorded as a Canadian species by Packard and 

 Verrill, in the "Canadian Naturalist and Geologist" for December, 1863. 

 Packard (who says that it occurs also in the Bay of Fundy) dredged it in 

 from 10 to 20 fathoms in Salmon Bay, and in 50 fathoms on the bank off 

 Caribou Island, in 1860 ; and Verrill off Anticosti and the Mingan Islands, 

 in 1861. Since then, it has b^en taken at many other localities in the Gulf 

 of St. Lawrence by Sir J. W. Dawson, and the writer, and on the Le Have 

 Bank by the U. S. Fish Commission (Smith and Harger). Hincks, in 1892, 

 described it as forming "large coral-like growths composed of many massive 

 branching segments, springing from a common base, foliated, contorted, 

 expanding upwards and terminating above in numerous smaller segments."* 



Porella concinna (Busk). 



Lepralia concinna, Busk (1852). 

 Lepralia Belli, Dawson (1859). 

 Porella concinna, Hincks (1880). 



Extremely abundant throughout the Gulf of St. Lawrence, at depths of 

 from about 10 to 50 or 60 fathoms, or more, attached to shells, stones, &c.
