NEMATOMORPHA. 



BY ROWLAND SOUTHERN. 



Numerous specimens belonging to the species Gordius 

 violaceus, Baird (" Catalogue of the Entozoa in the British 

 Museum," 1853, P- 36) were found on Lambay. Apparently 

 the only species recorded from Ireland is Gordius aquaticus 

 (Thompson's " Natural History of Ireland," vol. iv.). The 

 I^ambay specimens agree very closely with the description 

 and figures given hy Villot (" Revision des Gordiens," in the 

 Annales des Scie?ices Naturelles, 1886, p. 307). The first 

 parasitic stage of a species of Gordius was found in numerous 

 Enchytraeids from Lambay, viz., Enchytr&us albidus, 

 MesenchytrcEiis setosus, and F?-idericia bu/bosa. 



TURBEU.ARIA. 



BY ROWLAND SOUTHERN. 



Dr. Scharff found specimens of the Planarian Rhyncodemus 

 tarestris (Mull.) in June, 1905. It was also present in some 

 moss sent by Mr. Baring to the Museum. Several other 

 Planarian worms occur on L,ambay, but they have not been 

 identified.
