1905.] MR, A. E. SHIPLEY ON ENTO-PARASITES. 253 



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 fi-agments, 

 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 0-029 mm. long and 0*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 i-eported 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 anlmuja 

 from Florida. 



Spiroptera sp. ? 



A number of larvte identified by Dr. von Linstow as belonging 

 to some species of Spirojitera were taken fiom Centetes ecaudatus. 

 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 bvit one or two of the 

 specimens in question were encapsuled in membranous tissue, 

 probably peritoneal.
