titis may be present. The eyelids are swollen and tender, closed 

 or semi-closed, with an abundant flow of tears. The conjunctiva 

 is red and infiltrated. The cornea shows more or less opacity, 

 vascularity, and even ulceration or perforation. The lachrymal 

 canals may be distended. Finally the writhing worm is seen on 

 the eye, and usually toward the inner canthus. 



Treatment. This consists in the extraction of the parasites 

 with finger or forceps, or the washing of them out by a current 

 of water, and the application of non-irritant vermifuges. It is 

 important to search for them under the lids, and the membrana 

 nictitans. Serres has seen over a score of worms in one eye and 

 Guittard as many as one hundred, and in such cases it is difficult 

 to find and extract them all. By following the example of Bau- 

 danne, in detaching the eyelids with retractors and injecting the 

 conjunctival sac all those that are not esconced in the lachrymal 

 ducts will usually be reached. The vermifuges usually employed 

 have been dilute tincture of camphor, dilute tincture of aloes, and 

 infusion of wormwood, to which may be added infusion of quas- 

 sia. These agents may be injected daily for several days, so as 

 to destroy any hidden parasites when they emerge from the canals. 



Astringent coUyria may be necessary to correct any vascular 

 irritation, and a weak solution of silver nitrate (0.5:100) may be 

 applied daily to any existing ulcers. 



PARASITES OF THE KIDNEYS AND VICINITY. 



STEPHANURUS DENTATUS. SCLEROSTOMA PINGUICOI,A. LARD 

 WORM OF PIG. KIDNEY WORM. 



The term Stephanurus (stephanos crown, oura tail) was de- 

 rived from the broad 5-lobed clasping membrane of the tail of the 

 male, which has been supposed to represent a head-dress ; and 

 Dentatus (toothed) from the six firm tooth-like papillae which 

 surround the buccal orifice. The term Sderostoma Pinguicola 

 was adopted by Verrill from the papillae of the mouth and the 

 habitat of the worm in a cyst in the sublumbar fat (pinguis fat). 

 Louise Taylor of the Bureau of Animal Industry takes strong 

 grounds for abandoning the first name in favor of that of Verrill 

 and remanding the worm to the genus Sderostoma.
