male the body is divided into two nearly equal ovoid por- 
tions, one being the head, the other the thorax. 
The first species mentioned here was figured by the late 
Dr. Scoresby in his ‘ Arctic Regions/ It is found attached 
to the eye of the Arctic shark, and seems to blind it ; the 
sailors believe this shark to be blind, as it pays not the least 
attention to the presence of man, and does not draw back 
when a blow is aimed at it with a knife or lance. 
Lerneopoda elongata, Grant, sp. Grants SharJc-sucIcer. 
(Plate XX. fig. 2.) — This is three inches long; the thorax 
is long and narrow, and has two long cylindrical arms, con- 
siderably longer than the body ; ovaries nearly the length of 
the entire body. Dr. Baird mentions that a specimen of 
this Arctic species was taken from the eye of a shark taken 
on the English coast ; its arm-shaped appendages were in- 
serted into the cornea to the depth of nearly a fourth of their 
length. 
Lerneopoda Galei, Kroyer.— Length about three-fourths 
of an inch ; ovaries not quite equal to length of thorax. 
Pound on the Squalus Galeus , taken at Belfast. 
Lerneopoda salmonea, Linn. sp. — Body obovate, thorax
