Filaria labialis, Pane. This is a filiform cylindrical worm 

 measuring an inch and a quarter in length. The mouth is 

 armed with four papillae arranged in the form of a cross. The 

 tail of the female is blunt, the vaginal outlet being placed at a 

 very short distance from its extremity, and a little above or in 

 front of the anus. This parasite was found by a medical 

 student at Naples. It occupied the cavity of a pustule in the 

 upper lip, giving rise to considerable irritation. Only the male 

 worm is at present known.

Filaria hominis oris, Leidy. In the fifth volume of the 

 ' Proceedings of the Philadelphia Academy of Natural Sciences ' 

 (1850, p. 117) Dr Leidy furnishes the following description of 

 this worm as gathered from the examination of a simple spe- 

 cimen preserved in alcohol, and labelled as having been 

 " obtained from the mouth of a child. " Body white, opaque, 

 thread-like ; mouth round, simple ; posterior extremity obtuse, 

 furnished with a short, curved, epidermal booklet, 5^" in length, 

 by 3^0" in diameter at base. Dr Leidy offers some specula- 

 tions as to its origin, but from whatever source the worm was 

 obtained by the bearer, it seems to be an immature form. Its 

 length is five inches and seven lines. 



Filaria (Nematoideum) trachealis, Bristowe and Kainey. 

 This is another very doubtful worm. It was originally de- 

 scribed in the ' Pathological Society's Transactions' for 1855. 

 It evidently represents only a juvenile stage of growth of some 

 species of round worm. Eainey discovered a considerable 

 number of these worms in the trachea and larynx of a person 

 who died from a disease affecting the lower extremities. In- 

 dividually^iEe parasites measured about the ' in length. 



Strongylus (Filaria) bronchialis, Eudolphi. This is a small 

 nematode. The male measures rather more than half an inch, 

 whilst the female is upwards of an inch in length. The caudal
