Show the ‘ Proceedings ' * of last year, which were taken from the brain of the Quiscalus versicolor Vieillot, has described the parasite as a new species. Unfortunately the specimens were but fragments, bearing no head. The tail end is rounded. The breadth 0'21 mm. The body is uncommonly soft. The cuticle is smooth, not ringed. The eggs are O'029 mm. long and O'021 mm. broad. These Nematodes were found in the hinder part of both cerebral hemispheres. They formed a tangled mass lying below the pia mater. " The bird was reported to have dropped down suddenly from its perch ‘ in a fit.' " The position of these Nematodes in the brain is a very unusual one. Dr. von Linstow mentions that the only case known to him is that of Filaria helicina, found in the brain of Plotus anhinga from Florida. SPIllOPTERA S p . ? A number of larvfe identified by Dr. von Linstow as belonging to some species of Spiroptera were taken from Centetes ecciudatus. It is unfortunate that it was impossible to determine the species of this parasite, since, so far as I am aware, very little is known about the parasites of Centetes. All but one or two of the specimens in question were encapsuled in membranous tissue, probably peritoneal. List o f Hosts with their Parasites described in the foregoing Paper. TREMATODA.
