It may be of interest to compare these results with these tabulated for 
the Montrose Banks. Of Foraminifera, 12 genera and 20 species were 
obtained from Montrose, as against 4 genera and 7 species for the Clyde. 
All the genera of the Clyde were found at Montrose, and the species 
common to both were 2 Miliolina, 1 each Truncatulina and Polystomella. 
Of Ostracoda, Montrose furnished 6 genera and 18 species, as against 7 
genera and 24 species for tho Clyde. Only 1 Montrose genus was not 
obtained from the Clyde mud samples, while 4 Cy there, 3 Loxoconcha, 2 
Cytherura, and 1 Paradoxostoma were common to both. Three genera 
and three species of Copepoda were obtained from the Montrose mud, and 
only the burrowing form, Ectinosoma melaniceps, was common to both 
places. Nine genera and 9 species were furnished by the Clyde. 
How to Increase the Supply op Mussels. 
While the state of the law, and the methods of fishing the Clyde mussel 
beds remain as at present, no great increase of yield of mussels can bo 
looked for. By careful cultivation and wisely enforced regulations, the 
beds might be made to yield a regular supply of well filled mature mussels 
far in excess of the quantities which have yet been obtained from them. 
In any operations which may be conducted, nothing ought to be done 
which will in any way affect the navigation of the river ; and if the beds 
are farmed on approved and established principles of culture, nothing can 
be done that will be prejudicial to navigation. Besides, the depositing of 
ballast on any of the banks or flats ought to be strictly prohibited. Not 
only does ballast take up room where mussel cultivation aims to have mud, 
but its presence tends to heighten the level of the banks, and so restricts 
the area of first-class growing ground. 
The beds are worked at present almost exclusively from Port-Glasgow, 
where the Caledonian Railway have rails laid on the quay beside the place 
at which the mussels are landed. This enables the mussel fisherman to 
ship his mussels from the boat side for Moray Firth, Eyemouth, and East 
Coast fishing ports. The boats employed for transporting the mussels 
from the banks are ship's old boats, capable of carrying almost two or 
three tons of mussels. These boats are owned by mussel merchants resi- 
dent in Port-Glasgow, and are worked by mussel fishermen, who are 
natives of the northern counties of Ireland. The arrangement is that 
the merchants supply the boat and gear to the fishermen who receive,
