part of the state than records indicate. Schultz (1976) summarized 

 knowledge of all members of the genus in North America. The species 

 differs from M. halophilus from eastern North Carolina in the structure 

 of male pleopod 1 (Fig. 14). It is about 5 mm long.

This species lives in rotten logs and dense leaf litter in the Durham 

 region and in similar microhabitats in the salt marshes and other 

 marshes near the coast. It ranges from Massachusetts through New Jer- 

 sey to North Carolina (Schultz 1976), south to Georgia (Schultz 1975). 

 In forested land the species inhabits leaf litter and pulpy rot under loose 

 bark of well decayed deciduous logs, near spring and small streams 

 which are permanent and not subject to seasonal flooding or drying. In 

 coastal marshes it perhaps is inundated at extremely high tides. It lives 

 in leaf litter at the bases of reed grasses in salt marshes, frequently with 

 Porcellio scaber. The species is apparently common in eastern North 

 Carolina (Map 4) and is distinguished from M. medcofl by the differ- 

 ence in the configuration of male pleopod 1 (Fig. 15). Its length reaches 

 5.2 mm.

Because the species is tiny, unpigmented, and readily feigns death, 

 it can very easily be overlooked when making collections. It is the smal- 

 lest species in North Carolina, being only to 3.4 mm long. Its body is 

 cream colored (pigmentless) and highly tuberculate, and there is only 

 one ocellus. In the Durham region it lives in continually damp, but not 

 wet, places, such as well decayed, pulpy logs, or shaded leaf litter where 

 moisture is retained throughout the year. It was found in abundance 

 near Durham even in winter, in the pulpy remains of a damp, shaded 

 sycamore log that was partially covered with leaf litter. Gravid females 

 were collected in summer, but breeding season dates were not estab- 

 lished. At another site several hundred specimens were taken in a space 

 measuring about a square foot in area and two inches deep, in and 

 around part of a broken, decaying board. Since there were many pieces 

 of the board at the site, the isopods must have numbered in the thou- 

 sands. The species is easily identified (Fig. 16).
