five of the Filaria just described. In the other specimen the right 

 auricle and ventricle and the pulmonary artery in its ramifications 

 through the lungs are literally stuffed with Filariae. A portion of 

 the blood of this dog, given to me by Mr. Jone«, contains a great 

 number of the young of the Filaria. 



In relation to the symptoms which accompanied the presence of 

 these worms in the heart of the dogs while living, Air. Jones has 

 furnished the following notes : The heart containing the five worms 

 was taken from a male pointer dog whose appetite was voracious 

 and insatiable, and notwithstanding he was abundantly supplied with 

 food, he remained in a very lean condition. The heart and lungs 

 containing great numbers of worms was from a cur dog, who was 

 always so thin as to resemble a skeleton, and it was impossible to 

 benefit his condition with the most liberal supply of food. Both 

 dogs were of an exceedingly restless disposition. They did not die 

 in consequence of the presence of the Filariae, but were killed in 

 the course of some physiological experiments. 



1 60. f Filaria Diibia, Leidy. Body cylindroid. narrowed toward 

 the extremities, rolled in a transverse spiral. Head continuous with 

 the body, naked. Mouth minutely papillated. Tail acute. Length 

 9 lines, breadth i-3d of aline. 



Nine specimens were contained within two globular sacs of the 

 gastric mucous membrane of the albatross, Diomedea exulans, the 

 preparation having been obtained in the South Atlantic by Dr. 

 W. S. W. Ruschenberger, U. S. N. The sacs also contained each 

 a brown globular body about 3^^^ lines in diameter, divided by lines 

 into quarters, intensected by transverse corrugations. At one pole 

 of these enigmatic bodies was an elliptical aperture, and at the oppo- 

 site pole a small conical tail-like appendage. One of the bodies being 

 cut open, exhibited no regularity of structure. The Filar iae were 

 situated between the globular bodies and the walls of the sacs con- 

 taining them. 



161. Filaria Attamata f Rud. Body C3'lindrical, conical at the 

 extremities. Head convex ; mouth round, luiarmed. Caudal ex- 

 tremity of male incurved. Tail short, obtu.sely conical. Length of 

 female 4 inches, breadth i-3d of a line ; length of male 2 inches, 

 breadth one-fifth of a line. 



Five specimens were obtained by Prof. Baird from the abdominal 

 cavity of Sturnella ludoviciana. 



Two female Filarise having the same form as above, 5 inches in 

 length and J2 a line in breadth, were obtained by Prof. Baird from 

 the abdominal cavity of Colaptes auratus.
