fathoms, in April ; and another from the mouth of Loch Fyne, from 
40 to 60 fathoms. 
Many adult female and immature specimens were caught off the 
Island of Sanda, in 30 to 35 fathoms, on March 17. The ova were 
not yet fully developed, and the fishes had fed freely on Solens and 
Annelids. To extract the former from their shells and holes, the 
fish must exercise great rapidity and energy of motion. 
Solea solea. Sole. 
Two females and one male specimen were caught between Sanda 
and Pladda Islands, in 26 fathoms, on March 8. They had spawned 
some time previously to their capture. 
Solea variegata. Thick-Back. 
Two immature specimens from the Mull of Canty re, 65 fathoms.

Argentina sphyrcena. 
This deep-sea fish does not seem to he at all uncommon on the 
West Coast. By sinking a small-meshed trammel to a depth of 
30 and more fathoms, Mr Murray succeeded in getting a number 
of specimens, which probably would have been still larger but for 
the attacks on the captured specimens by Crustaceans and Starfishes. 
The specimens obtained in February had not yet spawned ; there 
were three obtained in 32 fathoms, between Little Cumbrae and 
Briguird Point, on February 7 ; and five obtained in 37 fathoms, in 
Loch Striven, on February 13.

A grant was made by the British Medical Association, on the 
recommendation of the Scientific Grants Committee of the Associa-
