Monopylephorus glaber Moore. 



Moore, 19053, p. 378 (sp. nov.). 



"In suitable localities . . . very abundant 

 about the shores of Vineyard Sound and 

 Buzzards Bay." Commonly found among 

 decaying vegetation, especially in brackish 

 waters. 



Monopylephorus parvus Ditlevsen. 

 Moore, 19053., p. 383. 

 " In a few cases large numbers were found living 



gregariously beneath stones at half tide on the 



south shore of Naushon." 



Limnodrilus subsalsus Moore. 



Moore, igosa, p. 392 (sp. nov.). 



"This species occurs in considerable numbers 

 along with Tubifex hamalus under stones at 

 half tide on the Acushnet River, above New 

 Bedford, Massachusetts." 



Family LUMBRICULID/E. 



Lumbriculus limosus Leidy. 



Several specimens* taken in brackish water at 

 either Tashmoo Pond or Great Pond by E. D. 

 Congdon, July 2, 1907. 



Class HIRUDINEA. 



Family ICHTHYOBDELLID^E. 



Ichthyobdellafunduli Verrill. 



Verrill and Smith, 1873, p. 624 (not listed from 

 this region). 



Recorded once during dredging; being taken in 

 Vineyard Sound, near Lucas Shoal (Fish 

 Hawk station 7562 *). Specimens occasionally 

 found upon Fundulus heteroclitus . 

 Ichthyobdella rapax (Verrill). 



Verrill and Smith, 1873, p. 625, 458 (Pontobdella 

 rapax, sp. nov.); Moore, 1898, p. 557 (Piscicola 

 rapax) . 



Vineyard Sound, quite common on the upper 

 side of Paralichthys dentatus. Verrill. Men- 

 emsha Bight, on Paralichthys dentatus. 

 Moore . 



Trachelobdella -vividus (Verrill). 

 Moore, 1898, p. 551. 

 Woods Hole, i specimen, collected by V. N. 



Edwards. This species occurs both in fresh 



and salt water. 

 Branchellion ravenelii (Diesing). 



Verrill and Smith, 1873, p. 624, 458, etc. 



(Branchiobdella ravenelii). 

 Vineyard Sound, on a sting ray, Myliobatis 



frcminvillei; August and September; several 



usually occurred together. Verrill. 



SIPUNCULIDA. 



Phascolosoma gouldii Diesing. 



Verrill and Smith, 1873, p. 627, 353, etc.; 

 Gerould, 1904, p. i-xn; Gerould, 1906, p. 77. 



Woods Hole, Newport. Gerould. Reported 

 from Uncatena Gutter (McMurrich); and 

 Vineyard Haven, near the bridge (Osburn). 

 Littorally, this is a common species and its 

 distribution is quite general along muddy 

 shores and on mud flats, but it seems to be 

 rare in deeper waters. Two specimens taken 

 by the survey near mouth of Buzzards Bay, at 

 Fish Hawk station 7674!, in 7 fathoms, mud 

 and sand. 



"The breeding season of Ph. gouldii at Newport, 

 R. I., extends from the middle of June to the 

 middle of August and probably later." Indi- 

 viduals laid eggs at Woods Hole, August 22, 29, 

 and September 3. Gerould. 



Reported by Verrill from the stomach of a skate 

 1266, 1346, i44 & , 147 (i) b , 166 (i)*. (Raja lewis?). 



a Specimens from points designated by an asterisk (*) were identified by Prof. J. P. Moore. Specimens from points desig- 

 nated by a dagger (t) were identified by Prof. J. H. Gerould. 



b Referred by the collectors to same species as a lot coming from station 78. This was found to include Phascolosoma I'ernUii 

 as well, but it is likely that most or all of the specimens here indicated were Phascolion strombi. 



Family SIPUXCULID^;. 



Phascolion strombi Montagu. [Chart 83.] 



Verrill and Smith, 1873, p. 627, etc. (Phasco- 

 losoma c&menlarium.) 



Vineyard Sound. Verrill. Dredged by the 

 Survey at a considerable number of (chiefly 

 inshore) stations in Buzzards Bay; a few 

 times in deeper waters of Vineyard Sound; 

 taken in 3 to 13 fathoms, for the most part on 

 bottoms of sand or sandy mud. This species 

 is most commonly found in the shells of gas- 

 tropods, which the worm plugs up with a sort 

 of cement. 



Fish Hawk stations: 7688 (i)*, 7699 (i)*, 7702 

 (several in Tritia)*. One specimen each 

 recorded from 1907 stations which coincided 

 approximately with the original stations 7652*, 

 7671*, and 7739*. 



Phalarope stations: 78 (several)f, 850, 86 (i)&, 

 93 (3)f, 94 5 9 86 > I0 9 & . XI 9 6 . i 2 6 . 1236, 125^,
