12 Mr. MoNTAGV's Description of several new or rare Animals, 
The abdomen appears to have three divisions: the first Joint or 
annulation is by far the largest on the upper part, but by its 
obliquity becomes narrow beneath: the margin or divisional 
line has a pectinated appearance under the microscope, similar to 
that observed in the common flea: the posterior joint is smallest, 
and is terminated with two long fleshy papillz furnished with four 
bristles regularly radiating : upon the upper part of the thorax 
close to the anterior end is a cylindric erect appendage beset 
with bristles ; this appears tubular, and seems to be the proboscis 
or trunk by which the animal takes its nourishment: should this 
be the case, and of which there seems no doubt, its manner of 
feeding must be curious, as it must turn on its back to apply 
this mouth to the skin of the bat. So strange and contradictory 
to experience is the formation of this insect, that, were it not for 
the structure of the legs, no one could doubt that the upper was 
actually the under part of the body, as well from the situation 
of the legs, as from that of the proboscis: the Joints of the legs 
however demonstrate otherwise, and the living animal examined 
in motion puts it beyond all doubt : the legs have four joints, in- _ 
dependent of the foot to which two remarkably hooked claws 
are fixed, and at their base a spongy substance: at the end. of 
the tibia next to the tarsus are a few annulations, like imperfect 
joints. : 3 | |

In another specimen examined, the body or abdomen ap- 
peared to have four joints, was more ovate, tumid, and destitute 
of the posterior appendages; the thorax and all the other parts 
similar to the first. his I Suspect to be the female; and the 
sexual distinction seems to be further exemplified by the posterior 
end of the former being bilobated verticall y, and when examined
