LEPRALIA. 307 
Sana Island, off which this and several very interesting 
mollusks and zoophytes have been dredged, is near the 
coast of Cantire, in Argyleshire. This coast, from Macri- 
hanish Bay to the Mull and Southend, is rich in alge and 
zoophytes ; but in visiting it some time ago, not having a 
boat, I had to rest satisfied with the rejectamenta on the 
strand; and there are few portions of the Scottish shores 
better fitted to gratify a naturalist. My friend, Mr. Hynd- 
man, of Belfast, to whom this curious Lepralia has been 
dedicated by Dr. Johnston, has every encouragement to 
cross again to Sana. Ireland is scarcely more than twenty 
miles from Cantire, in the county of Argyle. 
The cells of Mr. Hyndman’s Lepralia are described by 
Dr. Johnston as “ distinct, but contiguous, of a medium 
size, sub-globular, narrowed and somewhat raised anteriorly, 
the back smooth and thickish, but the base of the cells, or 
the space between them, is occasionally perforated with a 
series of punctures. The aperture has a neat and deep 
sinus on the proximal side, and the distal margin is plain 
and rounded. ‘The stout, short, tubular process on the 
posterior side of the cell is always very obvious; and there 
issues from it a long slender bristle, which, however, is often 
broken away. Ovarian capsules proportionably small.”
