one male. The latter named not being well preserved, will 
leave a void in my description. The females are white in 
colour, about twenty-five millimeters in length. They are 
cylindrical, slightly tapering towards their extremities: the 
anterior extremity being sharper than the posterior, which 
terminates in a short point. The body in the centre mea- 
sures from forty-five to sixty hundredths of a millimeter; 
while at the anterior extremity it is only from seven to eight 
hundredths over the mouth, and about twenty-four over the 
tail. The integument is somewhat hard and striated trans- 
versely; the striae being well marked and close together at 
the anterior part of the body, but more distant over the 
other parts of it. The distance between the lines varies 
from fourteen to twenty thousandths of a millimeter. The 
mouth is circular, without papillae. The oesophagus is 
round, of the same diameter as the mouth at the beginning, 
but swelling out at its termination. There is no stomach, 
but the intestine follows the oesophagus, and is of the same 
size at its commencement, but enlarges gradually. It is 
slightly sinuous, and terminates in the anus, which is situ- 
ated at a short distance from the tail. The genital organs 
are composed of two ovaries, one oviduct, &c. 
The Nematoides , without being very common, are not ab- 
solutely rare. M. Serres has often found them under the 
eyelids of the ox. I had an opportunity to study their cha- 
racteristics in six females found by M. Lafosse under the 
eyelid of a cow in 1855. From that time, though some 
details of their organization w T ere still wanting, I considered 
them as belonging to the genus Filaria, and I designated 
them in my course of lectures as the Filaria bovis. There can 
be no doubt as to the place which these worms are to 
occupy in our classification. Their slender, filiform, and 
elongated bodies ; their defined mouth w ithout papillae ; 
their almost terminal anus ; their double ovaries, united in 
one common oviduct, which is situated at a little distance 
from the extreme end of the anterior extremity ; and 
their embryons, W'hich are notched in the interior of the 
tubes of the oviduct, all show' that these Nematoides belong 
to the genus Filaria. The name of Filaria bovis may not be 
a proper one, as there are other Filaria found in these animals, 
and, therefore, an inconvenience might arise from its adop- 
tion. I propose to give them the name of Filaria pal- 
pebrarum , which w T ould indicate their locality. It is probable 
that the worms found in the globe of the eye of the ox are 
of the same genus as the one just described, and that their 
different locality is effected by transmigration, or, perhaps, 
they may deposit their embryons under the eyelids.
