 and Vineyard Sound, 1 to 8 fathoms; Watch Hill, Rhode Island . < . 

 Egg Harbor, N-ew Jersey. 



This species has a much finer and more delicate texture than C. 

 fata, due to the smaller fibers and spicules, as well as to the smaller 

 meshes of the skeleton. The branches are also smaller and much n 

 numerous than they usually are in that species.

Rhode Island to the Arctic Ocean ; northern coasts of Europe to Great 

 Britain. Abundant at Watch Hill, Ehode Island, on algae, in 4 to 8 

 fathoms; off Gay Head; Casco Bay; Bay of Fundy. 



HALICHONDRIA, species undetermined, a. 



Watch Hill, Rhode Island, associated with the preceding. 



Grows in large tuberous masses, on algaB, like the last, but has a 

 smoother surface and liner and firmer texture. (See p. 498.) 



HALICHONDRIA ?, species undetermined, &. (p. 334.) 

 Long Island Sound near New Haven ; Vineyard Sound. 

 Forms broad, uneven incrustations on the under side of stones, at 



low-water mark. Color when living, bright yellow. Oscules rather large, 



conspicuous. 



HALICHONDRIA ?, species undetermined, c. 



Vineyard Sound, on the under side of overhanging banks, on the salt 

 marshes near Waquoit ; on the piles of wharves at Wood's Hole. 



Forms large, irregular, thick masses, often containing much foreign 

 matter; surface uneven, rising into irregular prominences. Soft and 

 brittle. 



This is, perhaps, a species of Beniera Schmidt (Hymeniacidon Bow- 

 erbank).* 



RENIERA ?, species undetermined, a. (p. 334.) 



Vineyard Sound, 1 to 10 fathoms. Forms large, irregular, soft 

 masses, 3 to 5 inches in diameter, of a light yellow color when living. 



RENIERA 1 species undetermined, 1). 



Vineyard Sound, 3 to 10 fathoms. Forms large, irregular, thick 

 masses, with numerous acute, irregular, often ragged, conical promi- 

 nences, rising from its upper surface. 



* It was not studied carefully when recent ; and I have no specimens of tbi- 

 eral of the other species at hand, for most of the sponges were sent else\vlui. t>i com 

 parisou with named types, and have not yet heeu returned.
