BULLETIN OF THE 



filled by mud or by other ingredients of the bottom. I give below an 

 enumeration of the families of Annelids which are represented in the 

 collection ; the numbers in parentheses show in how many of the above- 

 named stations these families were found. Some idea may thus be 

 obtained of the manner in which the several families are represented in 

 making up the fauna of the region here investigated. 



Aniphinomidae (4). Ariciidse (1). 



Chrysopetahdae (1). Opheliidae (2). 



Aphroditidse (3). Scalibregmidse (2). 



Polynoidae (7). Cblorajmidee (5). 



Sigahonidae (2). Spionidse (1). 



Kephthydidae (2). CirratulidEe (2). 



Phyllodocidae (2). Maldanidae (5). 



Hesionidae (2).- AmiiLictenidae (1). 



Syllidae (1). Anipharetidae (5). 



Nereidae (3). Terebellidae (6). 



Eunicidae (34). Sabellidse (2). 



Goniadidae (3:). Serpulidae (5). 

 Glyceridae (1). 



According to their vertical range these families bear the following 

 relation to each other : * — 



The hundred-fathom line is not reached by the 

 Chrysopetahdae, Nereidae, 



Hesionidae, Scalibregmidae, 



SyUidae, Cirratulidse. 



The three-hundred-fathom line is not reached by the 



Amphinomidae, Ariciidse, 



Phyllodocidae, TerebelUdae, 



Glyceridae, SabelUdae. 



Below six hundred fathoms are found 

 Aphroditidae, Opheliidae, 



Polynoida), Anipbaretidaa, 



Eunicidae, Serpulidae. 



Among the families here enumerated, none has so important a bear- 

 ing on the character of the faunal region as that of the Eunicidae, even 

 should further investigation hereafter represent this fauna as having 

 many additional special features. Their representatives are fovmd in 



• I should expressly state, however, that the material seems to me still InsufBcient for 

 general conclusions.
