122 THE SCOTTISH NATURALIST 



the following Scottish occurrences : of the Common Dolphin 

 {Delphinus ddpJiis) two examples were stranded, one off 

 Inverness and the other off Johnshaven, Inverness-shire ; two 

 specimens of the White-beaked Dolphin {Lagenorhynchus 

 albirostris) were reported, off Port Errol, Aberdeenshire, and 

 off Wick, Caithness, respectively ; a couple of Bottle-nosed 

 Whales {^Hyperoodoii rostratus) occurred, one off Nairn and 

 the second off Mersehead, in the county of Kirkcudbright ; 

 while Rudolphi's Rorqual was represented by two specimens, 

 stranded off Crosskirk and John o' Groats, Caithness, 

 respectively. Although reported as the commonest species 

 on the English coasts, it is interesting to note that the 

 Common Porpoise {PJioccena phoccena) was not once recorded 

 from Scotland during the year, and only once in 191 3. 

 This useful publication concludes with a detailed account of 

 the teeth and rate of growth of the last-mentioned species. 

 The whole of the records of the various species detailed in 

 the Report are graphically indicated on three maps, which 

 contain full particulars as to date and length of each 

 specimen. 



Andrew B. Luvoni publishes ^ an interesting paper 

 entitled " Notes on the Cell-making of Megachile ligniseca, 

 Kirby." This species of Leaf-cutter Bee is somewhat rare, 

 and the paper makes no mention of the locality in which 

 the observations were made. M. ligniseca constructs its 

 burrows in solid oak, by which peculiarity in habit the species 

 may be readily identified. The author examined some fifteen 

 of the tunnels, most of which contained six cells made up of 

 several " oblong, almost square-ended pieces of leaf firmly 

 fixed together, and tightly fitting the burrows, the form of 

 which they take. The ends are formed by three or four 

 pieces of leaf cut to the shape of the tunnel, and arranged in 

 the same fashion as those used to stop the entrance of burrow. 

 These pieces are worked on to the ends of the cells in a 

 slightly concave form, the end of each cell fitting into that 

 of its predecessor after the manner of a number of thimbles 

 placed within each other, the whole assuming somewhat the 

 appearance of a large jointed green worm." The leaves
