contain Clynioia torquata. Further, seveial specimens of Glycera 

 americana were collected. On the shore of the pond in one place 

 Donax fosser appeared to have its residence, and among Solenensis a 

 single living Solecurtus gibbiis was found.

071 sonic Entozoa of Birds. — Prof. Leidy directed attention to 

 some specimens presented b}' Joseph Willcox, recently collected by 

 him in Florida. One of the specimens is the head of a Snake-bird, 

 Flatus anhmga, with a worm in sight, lying upon the brain, while 

 several other detached worms of the .same kind lay at the bottom of 

 the vial. The worm in its singular habitation was discovered by 

 Prof. Wyman in Florida in i86i and 1867, an account of which is 

 given in the Proceedings of the Boston Society of Natural History, 

 volume 12, 1868. Prof. Wyman had kindly presented Prof. Leidy 

 with a specimen of the head of the Snake-bird, with the worms 

 lying on the brain. This he had valued as a memento of his friend, 

 but it had unfortunately been lost in the fire at Swarthmore College 

 last autumn. Prof. Wyman states that the parasites were found 

 coiled on the back of the cerebellum between the arachnoid and pia 

 mater. The number varied from two to six or eight, or even more. 

 In nineteen birds they were detected in seventeen. Mr. Wilcox 

 found the parasites in four out of six birds examined. In the pres- 

 ent specimen of a head a single worm is enclosed between the two 

 laminae of the dura mater over the position of the interval of the 

 cerebrum and cerebellum. As the parasite appears not to have 

 been named, it was suggested that the name of its discoverer should 

 be associated with it under the name Filaria wymani. 



The accompanying four vials contain numbers of worms obtained 

 from the stomachs of the Snake-bird, the Cormorant, Graculus dilo- 

 phus; the White Pelican, Pelccanus trachyrhynchiis, and the Brown 

 Pelican, P. fitscus. All prove to be of the same species, the Ascaris 

 spiculigera. Specimens of these were also formerly obtained by 

 Samuel Ashmead in Florida from the White Pelican (Proc. Ac. 

 Nat. Sci., 1858, 112). The same likewise have been submitted for 

 examination by Dr. Elliott Coues, who procured them from the 

 White Pelican on the Red River of the North. See Birds of the 

 Northwest, 1874, 587.
