[743] INVERTEBRATE ANIMALS OF VINEYARD SOUND, ETC. 449 
4-™™ to 10™™, mostly about 5™™ to 6™™; diameter of the oscules, in dry 
specimens, abort 19. 
North Carolina to Cape Cod. Very common in Long Island Sound 
and Vineyard Sound, 1 to 8 fathoms; Watch Hill, Rhode Island; Great 
Egg Harbor, New Jersey. 
This species has a much finer and more delicate texture than C. ocu- 
lata, due to the smaller fibers and spicules, as well as to the smaller 
meshes of the skeleton. The branches are also smaller and much more 
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, Rhode Island, on alge, 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 algze, like the last, but has a 
smoo:her surface and finer and firmer texture. (See p. 498.) 
HALICHONDRIA ?, species undetermined, b. (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 2, species undetermined, ¢. 
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 Reniera 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 ?, species undetermined, b. 
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 this and sev- 
eral of the other species at hand, fur most of the sponges were sent elsewhere for com- 
parison with named types, and have not yet been returned.
