    PARASITIC WORMS WITH A NOTE ON A FREE-LIVING NEMATODE. BY R. T. LEIPER, D.Sc, Helminthologist to the London School of Tropical Medicine, AND SURGEON E. L.

A certain amount of collecting was done, however, during the outward voyage of the Terra Nova. A preliminary account is given, therefore, of the various forms and their hosts according to the geographical regions in which they were found. Tropical Zone.—On July 3rd and 4th, 1910, when the Terra Nova was in Lat. 22° 28' N., Long. 23° 05' W. (Stat, 23), and Lat. 20° 47' N., Long. 24° 06' W. (Stat. 25), two flying fish came aboard. From the contents of the alimentary canal of one a few Trematodes were obtained. In the gall-bladder of the other, a fluke, apparently a form of Polystomum, was found. Of these specimens only unrecognizahie fragments remain, so that no description of them is given. The flying fish were Exocoetus spilopus. On the 27th July, 1910, the Terra, Nova arrived at S. Trinidad, a, desert island in the South Atlantic in Lat. 20° 28' S., Long. 29° 25' W. (Stat, 36. 37). F
