ZOOLOGICAL NOTES 57 



its plumage except the tail. This tint, which was deepest on 

 the abdomen and flanks, included the entire shafts and webs of 

 the two outer primaries, the basal portions of the shafts of the rest 

 and of the secondaries, and the bases of the grey feathers of the 

 mantle. I sent the bird to Mr. Eagle Clarke for his inspection and 

 opinion on it. He tells me that the specimen, a female, was quite re- 

 markable for the extent and depth of the rose-colour permeating its 

 plumage. Mr. Howard Saunders, in describing a similar specimen 

 obtained at Wells, Norfolk, in November, remarks (Cat. Birds, Brit. 

 Mus., xxv. 212) that such instances must be considered unusual. I 

 have since seen two others. ALICE FOWLER, Inverbroom, Ross-shire. 

 [I have also seen rosy-coloured Black-headed Gulls at Oban, as 

 I have elsewhere made note of. J. A. H.-B.] 



Porbeagle Shark in the Moray Firth. A male Porbeagle 

 shark (Lain/ia cornubica), 84 feet long, was caught at Nairn on 

 3oth October last. I went to examine it, and took the following 

 measurements: From point of snout to pectoral fin, 27 inches; 

 length of pectoral fin, 16 inches; greatest breadth of tail, 28 inches. 

 It had the large, high anterior and very small posterior dorsal fin 

 of the species. It was bluish grey above and dirty white below. 

 It belongs to the variety with small teeth. I have also found the 

 variety with large teeth in the Moray Firth. The difference in the 

 teeth is certainly not a sexual character. Dr. Traquair was kind 

 enough to demonstrate that for me in the Royal Scottish Museum 

 some years ago. WM. TAYLOR, Lhanbryde. 



Barnacles on a Whale. Mr. Carl F. Herlofsen, of Buna- 

 veneader, Harris, recently presented to the Royal Scottish Museum 

 a specimen of a parasitic Copepod, Penella species, extracted from 

 the side of a whale caught off St. Kilda. Growing upon the 

 Penella were two specimens of Stalked Barnacle, Conchoderma virgata 

 (Spengler), a species which, though of world-wide distribution, has 

 seldom been recorded from Scottish waters. The association of 

 Conchoderma virgata with Penella has been noted on several 

 occasions, even where the hosts of the Copepod have been so 

 different as whale and sword-fish. JAMES RITCHIE, Royal Scottish 

 Museum. 



Hydraehnids in Forth and Tay. In the previous number of 

 the "Annals" (1909, p. 249) I recorded Arrhenurus cylindratus, 

 Piersig, from the Forth district, the record being based on half a 

 dozen females from West Lothian, which were believed to belong to 

 this species. The capture of two males and a female on iyth 

 September last in a pool near Lasswade, Midlothian, removes any 

 slight doubt there may have been as to the species being an 

 inhabitant of the district. Along with these Lasswade examples of 

 A. cylindrahis I captured five males of another Arrheimrus which
