Florida specimens of Bdella oblonga are without dark 
pigment, but dark material sometimes occurring inside the 
body gives the abdomen a mottled appearance. One speci- 
men from Florida (lot 90) has “black” pigmented eyes. One 
specimen from among several from Mt. Logan, Chillicothe, 
Ohio (slide 32M108al) and one from Bent Creek, Bun- 
combe Co., N. Car., each have the two lateral bristles of 
palptarsus subequal. In identifying this species one must 
bear in mind that the bristles of palptarsus have a varied 
appearance depending on orientation of the segment. In 
what I would call the optimum orientation four of the 
bristles are on one face of the segment (though near the 
edge) while a fifth (seventh) is on the opposite face 
(figure 8) .
