Paratypes.—USNM 45284. One individual from SQ 39 (in gray very fine sand; collected 23 April 1960); three individuals from SQ 46 (in gray silty very fine sand; collected 24 April 1960); two indi- viduals from SQ 49 (in gray very fine silty sand; collected 24 April 1960); two individuals from SQ 58 (in gray silty very fine sand; collected 24 April 1960). NMC 3476. One individual from SQ 54 (in gray silty fine sand: collected 24 April 1960). Depths (all paratypes), less than 2 m. Etymology.—"verrucosus" = L. "; Description.—Up to 45 segments. to 13 mm long. to mm diameter anteriorly, to mm at segment XI, tapering to mm posteriorly. Prostomium a little shorter than it is wide at the peristomium junction, with a small, thin- walled papilla anteriorly. Body wall covered with a sparse to very dense layer of raised papillae and small foreign particles, usually beginning just behind the clitellum in mature individuals, but occurring in anterior segments of immature specimens. Clitellum confined to segments XI and a small part of XII. Dorsal and ventral setae similar in number, size and shape: setae two per bundle in segments II to \ II and one per bundle from VIII to the terminal seg- ment; setae absent on segments X and XI l no modi- fied genital setae): all setae bifid, 40 to 65 m long. with the upper tooth thinner than, but about as long as the lower. Male and spermathecal pores paired in the line of the ventral
