BULLETIN OF THE BUREAU OF FISHERIES. 



Family SUBERITID^. 



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 



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 Tetkya was taken. 

 Phalarope stations: 141 (several), 143 (i small), 



144 (i), 146 (several), 147 (i), 148 (several). 



Also at 1909 repetitions of Fish Hawk station 



7634 and Phalarope station 146. 



Family HOMORRHAPHID^. 



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 algse. " 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 (i large mass), 

 7589 (i 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 112, 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, i (3 i 



to 10 fathoms. 



Chalina arbuscula Verrill. 



Verrill and Smith, 1873, p. 742, 391 (sp. nov.). 

 "Vineyard Sound, i 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 (i colony), 7670 (i colony), 7671, 7674 (i 

 mass), 7675 (i large colony); Phalarope station 

 ii (several colonies). Specimens from the 

 following points were originally identified as 

 C. oculata: Fish Hawk stations: 7524 bis, 7533 

 bis (2), 7536 bis (i), 7593 (i cluster), 7702 (i 

 clump), 7728; Phalarope stations: 11, 78 (i 

 piece), 81 (i piece).
