254 REPORT—1868. 
TUNICATA. 
The only catalogues for comparison with the thirty-nine Shetland Tunicata 
are Alder’s list of those of the Northumberland and Durham coasts (Catalogue 
of the Mollusca of the Northumberland and Durham Coasts, p. 101), which 
includes thirty species, my own very short list of sixteen observed in the 
Clyde district (“‘ The Mollusca of the Firth of Clyde,” Zoologist, 1857, p. 5703), 
and a third of twenty-one Hebridean species by Mr. Alder (Brit. Assoc. 
Report, 1866, p. 206).
