132 BIOLOGICAL SURVEY OF 



BRACHIOPODA 



Class ARTICULATA 



Order TELOTREMATA 

 Terebratiilidae 



Terebratulina d'Orbigny 

 Terebratulina septentrionalis (Couthouy) 

 This brachiopod is the only one from this Region and is 

 found very generally where the bottom is rocky in the outer 

 Bay. Stations D 68, 80, 98, 107, 132, 135 are typical ones. It is 

 usually covered with the sponge lophon chelifer and this is 

 the usual occurrence of this sponge in this Region. When 

 T. septentrionalis is found on a gravel or shelly bottom or 

 out beyond the mouth of the Bay the sponge does not cover it. 

 We dredged many and large specimens at 107, otT the western 

 end of Mount Desert Rock. I am indebted to Dr. H. W. 

 Shimer for the classification of this group. 



ANNELIDA 



In this phylum Dr. A. L. Treadwell has very kindly given 

 us the benefit of his counsel and communicated to us the 

 scheme of general classification which is here followed. 



Class CHAETOPODA 

 Subclass POLYCHAETA 



Polychaete annelids of the waters in the region which may 

 be called the mouth of the Bay of Fundy have been collected 

 and described by a number of workers: Stimpson (1853), 

 Verrill (1871-1881), and Webster and Benedict (1884). Ver- 

 rill (1884) catalogued all of the species listed in the works 

 of others, as well as his own, and thus gave us a very com- 

 plete picture of the Annelida of the New England coast as 

 known in his time. For Canada, Whiteaves (1901) compiled 

 a list of marine invertebrates which included many of the 

 annelids known also to Verrill for the eastern New England
