ble tentaculae, and its numerous podal hooks. It is capable of slowly progressing, by 

 means of its tentaculae. In the process, these are extended by having forced into 

 them the bright red corpuscles which fill the visceral cavity of the body, they then 

 attach themselves by their extremities to the surface upon which the animal is lying, 

 and by subsequent contraction the body is dragged after them.

 pair, commencing at the second setigerous segment and the most robust. Setae in two 

 rows, simple, in fasciculi of three to five. Podal hooks in two rows, five to eight in 

 each fasciculus, sigmoid, bifid at the free extremity. Intestine cylindrical, constricted. 

 Ovaries on each side of the intestine, extending four-fifths the length of the body.

 with from six to ten setae in two fasciculi. Setae simple, distally curved and grooved 

 and ending in a subulate point. Length up to eighteen inches, with as many as 420 

 segments. Raked from oyster beds, in Great Egg Harbor, N. J., where it is abundant. 

 The animal corresponds closely with De Biainville's description of a specimen, the 

 country of which, he remarks, he did not know.

 the remainder containing four. Setae in two fasciculi to each tubercle, simple and
