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. 
Ariciidee (1). 
Opheliido (2). 
Scalibregmide (2). 
Chloremide (5). 
Spionidz (1). 
Cirratulidee (2). 
Maldanide (5). 
Amphictenide (1). 
Ampharetide (5). 
Terebellide (6). 
Sabellide (2). 
Serpulide (5). 
Amphinomide (4). 
Chrysopetalidoe (1). 
Aphroditide (3). 
Polynoidee (7). 
Sigalionide (2). 
Nephthydide (2). 
Phyllodocide (2). 
Hesionide (2). 
Syllide (1). 
Nereide (3). 
Eunicide (34). 
Goniadide (3). 
Glyceride (1). 
According to their vertical range these families bear the following 
relation to each other :* — 
The hundred-fathom line is not reached by the 
Chrysopetalide, Nereida, 
Hesionideo, Scalibregmida, 
Syllide, Cirratulide. 
The three-hundred-fathom line is not reached by the 
Amphinomide, Ariciide, 
Phyllodocide, Terebellidao, 
Glyceridz, Sabellidæ. 
Below six hundred fathoms are found 
Aphroditidæ, Opheliidæ, 
Polynoidæ, Ampharetidæ, 
Eunicidæ, Serpulidæ, 
Among the families here enumerated, none has so important a bear- 
ing on the character of the faunal region as that of the Eunicidæ, even 
should further investigation hereafter represent this fauna as having 
many additional special features. Their representatives are found in 
* I should expressly state, however, that the material seems to me still insufficient for 
general conclusions,
