Lciicophrys Cochleariformis, Leidy. (PI. XI, figs. 62, 63.) Body 

 curved cochleariform. lycngth .135 to .iS mm. From the intes- 

 tinal canal of Lunibriculiis tcmiis. 



I found four individuals of this remarkable species in a dozen of 

 the LuDibriculus. While within the intestine it appears quiescent, 

 but when set free it moved about activel^^ by means of its long 

 vibrating cilia, with the bowl-end forward. 



Annulata. 



Naraganseta, Leidy. Body cylindrical, narrowed posteriorly ; no 

 lateral pinnse ; .segments numerous ; those anteriorly furnished with 

 a few simple cylindrical, lateral tentaculae ; anterior segments with 

 four rows of simple setse in fascicles ; succeeding few segments with 

 two rows of simple .setae, and two rows of cochleariform podal spines ; 

 posterior segments with four rows of cochleariform spines. Upper 

 lip distinct, conical, eyes none. 



Naraganseta Coralii, Leidy. (PI. XI, figs. 46-48.) Body black, 

 brownish or yellowish black, ninet}' segments in an individual, one 

 inch and a quarter in length. Eight comparatively short tentaculae 

 on each side of the anterior six segments ; three to the first seg- 

 ment ; first two the shortest, the third the most robust ; orange in 

 color, and except the most robust one, tipped with black. Anterior 

 ten segments with four rows of simple setae in fasciculi of five ; the 

 succeeding four segments with two rows of simple setae, and two 

 rows of cochleariform podal spines ; and the following segments 

 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 astraefonnis. It protudes the anterior part of its body 

 with the orange colored antennce. The latter are contractile, from 

 one to four lines long, and, with the exception of the third or more 

 robust one on each side, are tipped with black, as if to be subser^^ient 

 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.
