End, in January, 1905. The Sword-fish (Xiphias gladius, L.) 

 is occasionally reported by fishermen, but rarely captured. 

 Several instances of the occurrence of Eay's Bream (Brama rail, 

 Bl. Sch.) on the Cornish coast are collected by Day. In March, 

 1891, a specimen about 1 ft. 8 in. long was taken with a gaff at 

 Portscatho, and sent to the Marine Biological Laboratory by 

 Matthias Dunn. On the 12th of March, 1905, after a violent 

 storm, a large specimen was thrown up dead near St. Anthony 

 Lighthouse, Falmouth. In 1887 one was obtained in a Grey 

 Mullet seine at Scilly — the first capture off Cornwall in the open 

 sea (Cornish). Two occurrences of the Opah or King-fish 

 (Lampris lima, Gmel.) are recorded by Day, but it does not seem 

 to have been taken since 1865. The only two known British 

 examples of Luvarus imperialis, Rafin., were obtained in Corn- 

 wall, one off the Dodman on the 30th of April, 1866, and the 

 other exactly five months later at Falmouth. 



The Scad or Horse-Mackerel {Caranx trachurus, L.) is com- 

 mon and locally abundant in all the Cornish seas, usually 

 appearing in April and returning to deep water in October, but 

 the young often swarm in the coves throughout the winter. 

 Being of little commercial value, it is often very troublesome to 

 Cornish Mackerel and Pilchard fishermen by literally filling 

 their nets. This year (1907) it has been unpleasantly abundant 

 in the west about Scilly. The Pilot-fish (Naucrates dactor, L.) 

 is of frequent occurrence, not only as a companion of Sharks, 

 but also as a follower of vessels. One was taken in Falmouth 

 Bay on the 30th of September, 1899 ; two at Penzance in 

 November, 1903 ; and one close to St. Mawes on the 23rd of 

 June, 1907. Two examples of the Derbio {Lichia glauca, L.) 

 have been taken in the west, the last in 1878. A stray specimen 

 of Lichia vadigo, Risso, 19 in. long, was taken in a Pollack-net 

 off Prussia Cove in 1892 (Giinther, Ann. &Mag. Nat. Hist. ser. 6, 

 x. 335). The only British example of the Rudder-fish {Pammelas 

 perciformis, Mitchill) was found alive in a floating wooden case 

 about six miles from Penzance in October, 1874. About two 

 dozen examples of the Black-fish {Centrolophus pompilus, L.) are 

 recorded from Cornwall by Day. Holt describes six or eight small 

 specimens, 12 to 14 in. long, taken in a Mackerel-net near the 

 Runnelstone in 1891 (Journ. M.B. A. ii. 265). In June, 1900, a
