of digestion ; in the stomach was one which seemed as if it had 

 been boiled ; it was opaque white in colour, quite hard and 

 cracked longitudinally, even harder than the bones which were 

 beside it. 



On the posterior edge of the pupil of the right eye, was an ex- 

 ample of the parasite — Lemma elongata, Grant. — which is peculiar 

 to this species of Shark. The part of the animal which is visible 

 (the head and body being buried in the eye) consists of two 

 white vermiform filaments, each 1 i inch in length. After putting 

 the eye and its " appendages" in spirits, they contracted a little. 

 The eyes of the Greenland Shark with its parasite attached, were 

 first brought to this country by Capt. Scoresby. They were sub- 

 mitted to Sir David Brewster, who gave one specimen to Dr 

 Grant. It proved to be a new species, which Dr Grant named 

 Lemma elongata, and described and figured it in Brewster's " Ed. 

 Jl. Sc." vii., 147, t. 2, f. 5. (1827). The fish which are attacked 

 by this parasite seem to be rendered blind. " The sailors," says 

 Capt. Scoresby, "imagine this Shark is blind, because it pays 

 not the least attention to the presence of a man ; and it is, in- 

 deed so apparently stupid, that it never draws back when a blow 

 is aimed at it with a knife or lance." — [Arctic Regions, p. 539).

Descr. — The head is very distinct, of a horny texture, ovate, depressed, 

 broad at the base, and obtusely pointed in front, resembling very much the 

 shape of the body of the common Spider-Crab. The 2nd pair of foot-jaws is 

 large and well-developed, consisting of a large rounded, oval, basal joint, 

 and a more slender, curved, hooked terminal one, with a pretty strong tooth
