BULLETIN OF THE BUREAU OF FISHERIES. 
Family Suberitidze. 
Suberites compacta Verrill. 
Verrill and Smith, 1873, p. 744, 503 (sp. nov.). 
“Off Marthas Vineyard, 10 fathoms, sandy; 
Nantucket”; also on beach at Edgartown. — 
Verrill. Large dried masses of this sponge 
found in abundance upon the beach at the 
south shore of Nantucket. — Sumner. 
Family TethyiuE. 
Tethya gravida Hyatt. 
Hyatt, 1877, p. 34, footnote (sp. nov.); 1878, 
p. 1668, fig. only (here spelled “ Tethya gra- 
vata”). 
Buzzards Bay. — Hyatt. Dredged by the Survey 
at seven stations in the vicinity of North Fal- 
mouth; 3 to 6 fathoms, on various bottoms. 
Reported by Mr. Gray from Bird Island 
Light, a point not far distant from the Survey 
stations where Tethya was taken. 
Phalarope stations: 141 (several), 143 (1 small), 
144 (1), 146 (several), 147 (1), 148 (several). 
Also at 1909 repetitions of Fish Hawk station 
7634 and Phalarope station 146. 
Family Homorrhaphid/E. 
Halichondria panicea (Pallas). 
Verrill, 1873, p. 743, 498 (referred to in one 
place as “ Tedania”) . 
Off Gay Head.— Verrill. “One of the most 
abundant species of this [Woods Hole?] region 
[which] forms very irregularly shaped, uneven, 
pale yellow masses, attached to the stems and 
frondsof Phyllophora and other small algae, and 
often, as it grows larger, spreading over, entirely 
covering and destroying the algae.” Speci- 
mens assigned to this species by Dr. Cushman 
were dredged at Crab Ledge and at the western 
end of Vineyard Sound; 6 to 25 fathoms, on 
gravelly and sandy bottoms. — Survey. 
Fish Hawk stations*: 7582 (1 large mass), 
7589 (1 large piece), 7591 (2 small clumps 
attached to algae), 7605, 7606, 7607, 7608 
(large mass), 7609 (several pieces), 7722. 
Phalarope stations*: 34, 63. 
Halichondria caduca Bowerbank. 
Specimens thus identified by Dr. Cushman 
were taken at Phalarope stations 24 (Vineyard 
Sound), and 1x2, 123, 130, and 137 (Buzzards 
Bay). 
Halichondria sp. sp. 
Verrill, 1873, p. 743, 334, lists several unde- 
termined species of this genus, two of which 
(“species b” and “species c”) were taken 
within this region. Specimens of whose 
specific identity we can not be certain were 
taken in Vineyard Sound at Phalarope and 
Blue Wing stations 25, 32, 33, 36, 45, 46, 49, 
51, 56, 57, 58, 60, and 64, and in Buzzards Bay 
at Fish Hawk station 7639. 
? Reniera sp. sp. 
Verrill and Smith, 1873, p. 743, 334. 
Two undetermined species, “a” and “b,” are 
listed by Verrill from Vineyard Sound, 1 (3) 
to 10 fathoms. 
Chalina arbuscula Verrill. 
Verrill and Smith, 1873, p. 742, 391 (sp. nov.). 
“Vineyard Sound, 1 to 8 fathoms”, very com- 
mon. — Verrill. 
Chalina oculata (Pallas). 
Verrill and Smith, 1873, p. 742, 409, etc. 
“Off Gay Head, 4 to 15 fathoms”, “in the out- 
side cold waters.” — Verrill. 
Chalina sp. undet. [Chart 12.] 
Dr. Cushman believes that a confusion exists in 
Verrill’s descriptions of the two foregoing 
species. It is therefore necessary to enter as 
undetermined all the Chalinas taken during 
the Survey dredging. Members of the genus 
are recorded from scattered stations throughout 
Vineyard Sound and at the lower end of Buz- 
zards Bay, in 6 to 17 fathoms, on various bot- 
toms. Dried specimens, often of large size, 
are to be found in abundance upon the beach 
at Cuttyhunk Island and elsewhere. Mr. Gray 
has collected living specimens of what have 
commonly been regarded as Chalina arbuscula 
at Nobska Point and on Red Ledge, in Woods 
Hole Harbor. They are likewise known to 
occur on the Bureau of Fisheries pier at 
Woods Hole. 
Specimens from the following points were origi- 
nally identified by Dr. Cushman as C. arbuscula: 
Fish Hawk stations 7550 bis (several large), 
7666 (1 colony), 7670 (1 colony), 7671, 7674 (1 
mass), 7675 (1 large colony); Phalarope station 
11 (several colonies). Specimens from the 
following points were originally identified as 
C. oculata: Fish Hawk stations : 7524 bis, 7533 
bis (2), 7536 bis (1), 7593 (1 cluster), 7702 (1 
clump), 7728; Phalarope stations: 11, 78 (1 
piece), 81 (1 piece).
