LEUCOTHOE EERINA. 
27 5 
mous Crustacea (Ann. Nat. Hist, for February 1857), 
under the name of L. procera , but which we are not able 
to distinguish from the figure in Savigny’s work. This 
species appears not to be so common as L. articulosa , 
but yet we cannot suppose that it would be found at 
such distant parts without existing in intermediate 
localities. It may probably have been mistaken by 
collectors for the previous species, which might readily 
be done without attention. 
The following vignette represents the Cows’ (Gulls’) 
Castle, on the shores of the Moray Frith, kindly drawn 
for us by Mr, Small.
