3. Nematoideimi intcsti}iorum Armadillo7iis piUiilaris (pi. 11, Fig. 

 47). — This is also an anguillaliila-like entozoon, found coiled up 

 and adhering by the mouth to the epithelial layer of the intestine of 

 Armadillo pilhda7'is. It is white, cylindrical, attenuated, and acute 

 posteriorly. The intestinal canal presents the same appearance as 

 in the last, but the oesophagus is broader. Length i-53d inch ; 

 breadth i -360th inch. 



4. Nematoideum iiitegumenti L?inibncu/i litnosi (pi. 11, Fig. 48). — 

 This is a small entozoon which I found, six in number, doubled up 

 and motionless, contained in transparent oval cysts, imbedded in 

 the integument of the 9th, nth, and [5th annuli of a Lumbriailus 

 limosus. It resembled an embryo within an ovum. Its form is 

 cylindrical, subacute posteriorly, truncated anteriorly, colorless, and 

 transparent. No interior organs were observable, except a small, 

 round, transparent corpuscle posteriorly, and anteriorly a probos- 

 cidiform body, partly projecting from the anterior extremity. 

 Length i -560th of an inch.
