Beauchamp in 1913 described a new species of Turbellarian worm (alloeococl) which he called ~Ionoophorurn graffi. The specimens upon wliich the description was based were few in number, and all sexually immature. Due t o the incomplete description of the species, its taxonomic position is in doubt ; Reisingel. ( '26) included it in his genus Enterostomula, wliilc
In collections made during the summer of 1933 a t Curritucli, North Carolina, A nuniber of specimens of this species were encountered, and A detailed study of them has lncen made. Chrritucl; Souiicl is a n inlet emptying into Albemarle Souncl. This latter is a n important link in the Atlantic Tnland TTaterway of the TTnitcd States, a i d its connectioii with the ocean is 11)-way of a long tortuous passage formed blv barrier reefs and islands. Hence, while the salinity of the water is usually IOW, it varies d e ~m d i i i g upon tides, storins and winds. In the last few years the government has constructed locks in a n eftfort to prevent this variation, aiid to reduce the salinity. In its variable salt content this habitat is similar to that reported by Beauchamp a t St. Jeaii de Luz in France.
Collections were niade in eel grass and sand in 6 inches to 2 feet of water. Tn 193'7-38 additional collections weix made, hut the cel grass had disappeared and no worms were obtained. I n 1939 a few animals were taken from Currituck, and sereial appeared in collections made from a salt marsh at the foot of Cornwall Street in Norfolk, Virginia.
