LONGPORT IX SEPTEMBER. IO7 



one, or possibly on the young fry. Mouth downward, and 

 with eager motions, it bent its. energies to that purpose. It 

 expanded its exterior lobes and flattened them over the jelly 

 mass, gathering together in the manner of fingers all four of 

 its lappets, the better to grasp its food. Backing off as far 

 as the dimensions of the tumljler permitted, it returned again 

 and again to the charge, evidently hampered for want of 

 " sea room," in the curve of the tumbler where the jelly mass 

 lay. Finally it did envelop one of my little ciliated friends 

 and caught it in its embrace, but whether the morsel entered 

 its mouth or not I failed to see. The whole of the jelly mass, 

 which seemed to be the object of attack, looked to me to be 

 too large for the small mouth and the almost linear stomach. 

 How much both could be distended I am not prepared to say, 

 since I did nut see the food enter. I can only assert that from 

 its behavior the attacking animal was evidently hungry, and 

 earnestly seeking food to the best of its ability under unnat- 

 ural conditions. 



This species answers to the description of Bolina vitrea, 

 which Agassiz found only at Key West, Florida. Either 

 there are two very similar species, one with a northern and 

 the other a southern habitat, or else the one species was 

 brought as far north as Longport by storm currents, a suppos- 

 ition which would not agree with the fact of the same species 

 ha\ing been seen much earlier in the season and in great 

 abundance in the bay waters of Longport at a previous time. 



Whilst examining these Bolinas, another species in com- 

 pany with them attracted my attention as presenting interest- 

 ing differences. This was larger, pear-shaped instead of 

 rounded, and was further distinguished by small elevations or 

 papillte upon its surface, and by the strong and very distinct 

 and rich coloring of the cilia. It lived seventy-eight hours 

 after being brought in from the sea. This I supposed to be 

 an Eiicharis of the family Mnciniidae, a southern species 

 btought hither by storms. 



The next time mv collection of material was examined.
