Ltimbruu/us Tc?iuis,'L,&\dy. (PI. XI, fig. 64.) Body cylindrical, 

 linear, bright red, composed of six or more segments ; ninth to the 

 eleventh segment, inclusive, slightly thickened ; two generative aper- 

 tures on each of the ninth segment ; four rows of podal hooks, an- 

 teriorly five or six in each fasciculus, posteriorly three or four in 

 each fasciculus. Length up to an inch and a half, by the fourth of 

 a line in breadth. Abundant about the roots of grasses on the shores 

 of a sound on Point Judith. 



This article is an extract from Marine Invertebrate Fauna on the 

 Coasts of Rhode Island and New Jersey, by Jo.seph Leidy. Journal

Dr. Leidy exhibited the heart of a dog, in which the right auricle, 

 right ventricle, and the pulmonary artery and its branches were 

 literally stuffed with worms. Minute worms have long been known 

 circulating with the blood, and termed Hcnnatozoa. About five years 

 since Dr. L. described, in volume 5 of the Proceedings, the worm 

 exhibited this evening as Filaria Canis cordis. The males measure 

 five inches in length, the females ten inches. 



Two hearts were brought to Dr. L. by Mr. Jos. Jones, of Georgia ; 

 one, that of a pointer, had in it five worms ; the other, that of a cur, 

 was the one exhibited. It is probable that both venae were also 

 filled, as the portions of those vessels that remained were blocked 

 up. The animals did not die from the presence of the entozoa, but 

 were killed in the course of some experiments. The cur was ema- 

 ciated and voracious, restless when awake, and disturbed in its .sleep.
