Ferry. One was taken to Dundee for exhibition ; the others were 
brought to Edinburgh for the same purpose. By permission of the 
proprietors, the author was enabled to examine the latter specimens, 
and to acquire for the Anatomical Museum the viscera and other 
parts. One was a large female, 11 feet 8 inches in length; the other, 
a smaller female, 8J feet long. Colour, bluish-grey ; sides of body 
marked with a number of transverse stripes ; lateral line distinct. 
The author then recorded several measurements of the larger 
specimen, of which the more important were as follows : — 
Ft. in. 
From tip of snout to end of tail, . . 11 8 
,, to back of 1st dorsal fin, . 6 0 
,, to back of 2d dorsal fin, . 9 0 
„ to antr. edge of ventral fin, 7 9 
„ to antr. edge of pectoral fin, 3 5 
Height of 1st dorsal fin, . . . .07 
,, 2d dorsal fin, . .0 5^ 
Between tips of tail-lobes, . .29 
Length of pectoral fin, . . . .18 
,, ventral fin, . . . .13 
A specimen of the parasitic crustacean, th e Lerneopoda elongata , 
was attached to one of the eyes of the smaller specimen. 
The author then gave an account of the visceral anatomy of this 
shark ; all the measurements given being from parts of the larger 
specimen. The stomach possessed, in addition to the large sac, a 
posterior pyloric compartment from which the pyloric tube arose, 
which curving for 6 inches forwards, terminated by a very con- 
stricted orifice in the duodenum. 
The duodenum was a cylindrical tube, 3 feet 2 inches in length. 
It ran at first forwards and then passed backwards to end in a 
dilated part of the intestine 13 inches long, which contained the 
transversely arranged spiral valve. A short rectum, 7 inches long, 
passed from the spiral valve back to the anus, and into this part of 
the gut the duct of an ovoid glandular body, attached to the outer 
coat of the rectum, opened. The biliary and pancreatic ducts 
pierced independently the wall of the duodenum, where it bent on 
itself, and between their opening and the pyloric orifice two large
