Family ENCHYTRAEIDAE. Reference: 

 Nielsen and Christensen, 1959. 



CemosvitovieUa immota (Knollner, 1935). Mas- 

 sachusetts. In salt marshes, above high tide 

 line. (Lasserre, 1971.) 



Enchytraens alhidus Henle, 1837. Maine to 

 North Carolina, but jn'obably a cosmopoli- 

 tan species. A very tolerant species whose 

 marine habitat is usually decaying seaweed, 

 or under stones, near the high tide line. 

 Also inhabits salt marshes, compost heaps, 

 sewage beds and effluents. (Moore, 1905; 

 Welch, 1917; Lasserre, 1971.) 



Enchytraeus capitatiis Biilow, 1957. Massa- 

 chusetts and North Carolina. In seaweed 

 deposits, and meiobenthic on the upper 

 shore of sandy beaches. (Lasserre, 1971.) 



Hemigrania postclitellochaeta (Knollner, 1935). 

 Massachusetts and North Carolina. Sub- 

 tidal, 6 to about 70 m depth. In coarse 

 sand. (Lasseri'e, 1971.) 



Henlea ventriciilosa (Udekem, 1854). Massa- 

 chusetts and North Carolina. Above high 

 tide line, in salt marshes. (Lasserre, 1971.) 



Lumbricillus codensis Lasserre, 1971. Cape Cod 

 Bay, Mass. Subtidal, 6 to 16 m depth. 

 In sand. (Lasserre, 1971.) 



LumbriciUns lineatus (Mtiller, 1774). Maine to 

 Massachusetts. Upper littoral zone. In salt 

 marshes and seaweed deposits. (Moore, 

 1905; Welch, 1917; Lasserre, 1971.) 



Marionina achaeta Lasserre, 19fi4. Massachu- 

 setts and North Carolina. Intertidal; me- 

 iobenthic, on upper shore and at ground 

 water level on lower shore. (Lasserre, 

 1971.) 



Marionina preclitellockaeta Nielsen and Chris- 

 tensen. 1963. Massachusetts and North 

 Carolina. Intertidal; meiobenthic in sand 

 at ground water level on middle to lower 

 shore. (Lasserre, 1971.) 



Marioyiina southerni (Cernosvitov, 1937). Mas- 

 sachusetts and North Carolina. Intertidal. 

 In seaweed deposits. (Lasserre, 1971.) 



Marionina spicula (Leuckart, 1847). Massa- 

 chusetts and North Carolina. Intertidal. 

 Meiobenthic in sand, and in seaweed depo- 

 sits. (Lasserre, 1971.) 



Marionina suhterranea (Knollner, 1935). Mas- 

 sachusetts and North Carolina. Lower in- 



tertidal. Meiobenthic in sand at ground 

 water level. (Lasserre, 1971.) 

 Marionina welchi Lasserre, 1971. Cape Cod 

 Bay, Mass. Subtidal, to about 15 m depth. 

 In sand. (Lasserre, 1971.) 



Family MEGASCOLECIDAE. 



Pontodrilus hermudensis Beddard, 1891. Vir- 

 ginia. Above high tide line, and intertidal, 

 on sandy beaches and under decaying sea- 

 weed. The record of this species is cited 

 in Wass (1965) and is apparently based 

 on specimens identified by J. P. Moore prior 

 to 1931; it is possible that these are refer- 

 able to P. gracilis. Both species are keyed 

 out, however, for the sake of completeness. 



Pontodrilus gracilis Gates, 1943. Florida and 

 Beaufort, N.C. (latter record based on a 

 personal communication by E. C. Haff, Uni- 

 versity of Georgia). Intertidal, on sandy 

 beaches; also banks of rivers where water 

 is brackish. (Gates, 1943.)
