Poly dor a anoculata Moore. 

 Moore, 1907, p. 197 (sp. nov.). 

 " Uncommon. Usually taken in association with 

 colonies of Amaroecium pellucidum in 7 to 17 

 fathoms in Vineyard Sound. Less often on 

 piles among Cynthia in Little Harbor and with 

 Polydora co Ionia at Vineyard Haven. A 

 specimen taken on July 14 contained nearly 

 mature eggs." 



Polydora colonia Moore. 



Moore, 1907, p. 199 (sp. nov.). 

 Vineyard Haven, on piles, among sponges and 

 tunicates, forming large colonies of "soft mu- 

 coid tubes. ' ' Specimens containing large eggs 

 were noted in July. 

 Polydora littorca Verrill. 



Verrill, 1873, p. 603, 345 (Polydora ciliatumJ). 

 Naushon Island, in muddy sand, at about half 

 tide. A. Agassiz. Young frequently taken in 

 tow nets. Verrill. Very common on muddy 

 shores. Moore. Great Pond* (E. D. Congdon, 

 col.). 

 Polydora sp. undetermined. 



Fish Hawk station 7769 (i)*; Phalarope station 

 77 (2)*; shore at Tarpaulin Cove, sandy beach.* 



Family MAGEXONID^E 



Magelona rosea Moore. 



Moore, 1907, p. 201 (sp. nov.). 



"This species has been found only on a sandy 

 beach, chiefly below low water, in a little 

 shallow bay on the Buzzards Bay side of 

 Woods Hole. Prof. E. A. Andrews found it at 

 the same place about ten years before it came 

 to my notice, and has described a specimen 

 under the name of M. papillicornis Muller. 

 The remarkable larvae have been described by 

 Fewkes (as Prionospio tennis) from Newport, 

 and by Andrews from Beaufort, N. C., and 

 Woods Hole." 



Family CH^TOPTERID^;. 



Chastopterus pergamentaceus Cuvier. [Chart 67.] 

 Verrill, i882b, p. 370; 1884, p. 665; Mead, 1897, 

 p. 271. (Strangely omitted from Verrill and 

 Smith's Invertebrates of Vineyard Sound.) 

 Naushon Island. Verrill. In Buzzards Bay, 

 tubes (never containing worms) were fre- 

 quently brought up by the dredge, particu- 

 larly in the upper half and at inshore stations, 

 occurring at depths of 2 to 8 (once at 12) fath- 

 oms, on various bottoms, though relatively 

 more common in mud; not recorded from the 

 Sound. Survey. Hadley Harbor. Moore, 

 Treadwell. Ram Island; shore of Woods Hole 



ChcEtopterus pergamentaceus Continued. 



Harbor in front of Marine Biological Labora- 

 tory supply department building. G. M. 

 Gray. Mr. Gray notes that this worm is par- 

 ticularly common among the roots of eelgrass, 

 where it may readily be dug up after mowing 

 down the latter with a scythe. On the shoal 

 between Ram Island and Devils Foot, 13 

 specimens were thus obtained in the course 

 of a few hours by J. F. McClendon and C. B. 

 Bennett.

 July and August may be artificially fertilized- 

 Mead, Treadwell. Commensal crabs of the 

 genus Pinnixa are of frequent occurrence in 

 the tubes of this worm. 

 Spiochcetopterus ocnlatus Webster. [Chart 68.] 



Buzzards Bay, chiefly in lower half; two records 

 from Vineyard Sound; dredged in 3 to 17 

 fathoms, chiefly in mud or mixtures of mud 

 and sand. Survey. This worm lives in a 

 slender, quill-like tube, marked by numerous 

 annular thickenings, and buried upright in the 

 mud. Moore.
