Nearly all tlie specimens I have seen from deep water off the Southern coast 

 of New England are small, and the great majority of them were inhabiting 

 carcinoQcia overgrown by or composed of Epizoanthus Americanus Verrill. 



Eupagurus politus, sp. nov. 



Plate II. Fig. 5. 



The carapax is not suddenly narrowed at the bases of the antennae, where 

 the breadth is equal to the length in front of the cervical suture, and not ros- 

 trated, the median lobe of the front being broadly rounded and not projecting 

 as far forward as the external angles of the orbital sinuses, which are acute and 

 each usually armed with a short spine. 



The eye-stalks, including the eyes, are nearly four fifths as long as the 

 breadth of the carapax in front, stout, and expanded at the very large black 

 eyes, which are terminal, not oblique, compressed vertically, and broader tlian 

 half the length of the stalks. The ophthalmic scales are small, narrow, and 

 spiiiiform at the tips. 



The peduncle of the antenna is about as long as the breadth of the carapax 

 in front, and the ultimate segment about a third longer than the penultimate. 

 Tlie upper flagellum is much longer than the ultimate segment of the pe- 

 duncle, while the lower is only about half as long as the upper, slender, and 

 composed of ten to twelve segments. The peduncle of the antenna reaches 

 slightly beyond the eye. The acicle is slender, slightly curved, and reaches 

 to the ti]) of the peduncle, and inside its base there is a minute tooth, while 

 outside there is a straight spine toothed or spined along its inner edge, acute at 

 the tip and half as long as the acicle itself. The flagellum is nearly naked, 

 and about three times as long as the carapax.
