I found also at Lincoln College a Philodinian resembling 

 probably a variety of this species. I named it provisionally 

 P. cloacata. Its chief characteristics are as follows : Size 

 equal to P. megalotrocha. Body plump, quickly contracting to 

 the foot, which is slender and 4-jointed. Just anterior to the 

 foot is a large dome-like projection showing like a knot in the 

 outstretched foot. Under this the cloaca lies. The toes are 

 particularly long. Corona ample. Jaws at right angles to 

 length of body, usually greatly obscured. Teeth 2. Cloaca 

 very large. No brain observed. Dorsal antenna multisetate, 

 3-jointed. Eyes oblong-oblique.

 where he has recorded the species.
