On the 13fch November, 1907, a fislierman (James Gourlay) brought a plaice about 10^ iiiclies in length and normal in coloration which presented on the right side above the lateral line an elongated elastic swelling. The tumour was some-what irregularly elevated, and at first sight it resembled, from the irregular prominences, the condition resulting from an injured or diseased spine. On the left or white surface the tumour was more uniformly elevated, forming an elon-gate-ovoid mass 3^ inches in its long or antero-posterior diameter, and If inch in its transverse at the widest part, which was median. It was slightly narrowed at each end and of the same soft elastic nature as on the dorsum. On Ann. i& Mag. N. Hist. Ser. 8. Vol. i. 25
