 Pentacta frondosa, Jaeger (1833) ; and Stimpson (18.53). 

 Cuciimaria frondosa, Forbes (1841) ; and H. Theel (1886). 



Grand Manan. " Nothing can exceed the profusion in which this species 

 exists in some parts of the islands. It is found just below the ordinary 

 low-water mark on rocky shores, and is, therefore, exposed at spring tides. I 

 have seen areas of several square rods entirely occcupied by them. The 

 largest observed was nine inches in length and three wide. They are usually 

 black or dark purple above and pale brown or yellowish below. Some speci- 

 mens are of a uniform bright yellow. They always adhere by one side — 

 that on which the suckers are most developed. Ihey never bury themselves, 

 but are found on the surface of the rocks, and sometimes in chinks or among 

 large pebbles " (Stimpson). " Passamaquoddy Bay, — also L'Etang Harbour, 

 N.B., very large " (Ganong). Gulf of St. Lawrence, — near Ellis Bay, Anticosti
