the broad expanse of the beach, had led him to suspect that he 

 would find them living in the greatest profusion in the dredgings 

 off the coast of Noank. In this view he had been disappointed, 

 though man}' living individuals were obtained in dredging, 

 adhering to hydroids, sponges, and the roots of fuci. The 

 number of species observed was small, though the individuals of 

 several of them were numerous. In the best condition, and espe- 

 cially abundant, were two Foraminifers, a Miliola, and a Rotalia, 

 exhibiting some variety of form. 



The Miliola resembles the Quinqveoculina meredionalis of 

 Dorbigny, and is probably the same species. The shell, from |th 

 to ^ 111 of a line in breadth, is white and more or less translucent, 

 or is colorless and transparent. It exhibits five compartments or 

 cells, in the mouth of the last and largest of which there is a 

 blunt, conical tooth. The interior soft structure was yellowish- 

 brown, or pinkish-brown, darkest in the smallest cell, successively 

 lighter in the others, and sometimes nearly colorless in the last or 

 largest cell. In the last cell, and less frequently in the second 

 cell, the soft matter exhibited many globules of transparent, 

 colorless liquid. In the active condition the animal protruded a 

 multitude of exceedingly delicate pseudopods, which, radiating 

 from the mouth, ramified and frequently anastomosed in the most 

 intricate manner, as usual among Foraminifers. 



The Rotalia is a beautiful, spiral, many-chambered shell, from 

 the tVfch to the ^th of a line in breadth, and strongly resembles 

 the Rosalina varians, as represented in Figure 8, Plate III. of 

 Schultze's Polythalamien. The shell is white and more or less 

 translucent, and is composed of from twelve to eighteen cells. 

 The soft structure within is dark-reddish or yellowish-brown in 

 the smallest cells, light brown or yellowish in the larger cells, and 

 faintly yellowish or colorless in the largest cells. Pseudopods 

 radiated everywhere from the minute pores of the shell. 



A few Polythalmous shells were observed, which appeared to 

 be composed of particles of sand cemented in the same manner as 

 in the fresh-water Difflugians. One of them was a spiral shell 

 like a Rotalia, composed of eighteen cells, and measuring about 

 J tli of a line in breadth. The soft structure within the smallest 

 cells appeared to be amber-brown. 



Anotfier of these arenaceous shells resembled in its shape and 

 the alternation of the cells the Textilaria agglutinans of Dorbigny, 

 of the West Indies. A specimen of thirteen cells was about the 

 1'oth of a line long by T ^ of a line at the broad end. The soft 

 structure was reddish-brown within the smallest cells, becoming 

 successively lighter in the larger cells, until in the last or largest 

 it was colorless, or nearly so. 



A third form consisted of a straight or slightly bent series of 

 cells, for the most part oblate spheroidal, and successively in- 

 creasing in size. The first cell is globular and larger than the few
