of simple setse, and two rows of cochleariform podal spines ; and the following seg- 

 ments with four rows of cochleariform podal spines in fasciculi of four to six. Point 

 Judith. 



This curious worm lives in tubes within the dead portions of Astrangea astrceformis. 

 It protrudes the anterior portion of its body with the orange colored antennas. The 

 latter are contractile, from one to four lines long, and with the exception of the third 

 or most robust one on each side, are tipped with black, as if to be subservient to the 

 impressions of light. Its setae are quite simple, as represented in figure 47, and are 

 about the fifth of a line in length. The podal spines consist of a long style ending in 

 a bowl, like that of a spoon, as represented in figure 48. 



For the new genus, of which the worm just described is the type, I have adopted 

 the Indian name Narragansett, being that of the bay, on the shores of which the 

 animal was first discovered. 



34. Sabella oculifera, Leidy. (PI. XI. figs. 55 — 61.) Body demicyllndroidal, pos- 

 teriorly narrowed, one hundred and thirty-eight setigerous segments to an individual 

 one and a half inches in length. Tentaculae twenty-four in number, arranged in the 

 four-fifths of a circle, decreasing in length towards the extremities of the latter, re- 

 flected, supplied with about forty-eight secondary tentaculae, arranged in pairs ; two 

 or three black eye spots on the back of the longer tentaculae. Two rows of setae in 

 fascicles of about six, and two rows of podal hooks, in transverse series of ten. Setae 

 in the third to the ninth segment inclusive, in major part spade-shaped with a short 

 subulate point ; of the following segments all like the latter. Podal hooks in 

 the first to the tenth segments inclusive, bird-like in form, associated with opposing 

 spade-like podal spines. Podal hooks of the following segments smaller than those 

 anteriorly. Worm living in tough tubes composed of mud, and found in a horizontal posi- 

 tion partially concealed beneath masses of Astrangia astrceformis. Point Judith. 



The plumose tentaculae with the dark eye specks on their back render this worm 

 a beautiful object. The surface of the tentaculae is everywhere covered with vibrat- 

 ing cilia. By transmitted light the blood appears of a bright green color. 



35. Clymene urceolatus, Leidy. Body cylindrical, composed of segments of various 

 lengths, twenty-six in number including the head and caudal appendage. The anterior 

 eight segments the shortest ; the seven preceding the last ten the longest ; those in 

 advance of the third, and intervening to this and the sixth and the ninth, without 

 setae. Head obliquely truncated, concave, with a thin acute margin. Mouth inferior 

 triangular. Caudal appendage large, urceolate, with the margin entire. Color 

 reddish brown. Length five inches; breadth one and a half lines. Raked from the 

 mud in a sound about six feet deep, near Atlantic City, N. J.
