58 ANNALS OF SCOTTISH NATURAL HISTORY 



by the two species, P. intermedius, Lilljeborg, and P. polyphemoides 

 (Leuckart) ; but if we take as our guide the great work by Prof. 

 Lilljeborg on the " Cladocera of Sweden," recently published, it is 

 evident that the Podon polyphemoides of Hodgson is really the 

 P. leuckartii, G. O. Sars. Hodgson's formula gives 6 seta? (or 

 hairs) for both branches of the second antenna?, which agrees with 

 Sars's P. leuckartii but not with Leuckart's P. polyphemoides, which 

 has 7 seta? on the lower branches. On the other hand, Leuckart's 

 species agrees with P. intermedius, Lilljeborg, in the number of seta? 

 on the branches of the second antenna? ; but in P. polyphemoides the 

 end joints of both branches are distinctly shorter than the similar 

 joints in P. intermedius. It is interesting to note, that while Podon 

 leuckartii appears to have an extensive distribution on the east 

 coast, the species most extensively distributed on the west is Podon 

 intermedius. T. SCOTT, Aberdeen.

Vegetable Colouring-Matters used as Dyeing" Materials in the 

 Scotch Highlands. In The Essex Naturalist (1901, p. 45) is a 

 list (sent by the Duchess of Sutherland to Professor Meldola, as 

 compiled from various local sources of information for her book on 

 Woman's Work : Highland Home Industries] which we reproduce 

 below (without alteration of scientific names) because of its local 

 interest, and in the hope that it may elicit further information as to 

 the use of dyes made from native plants at the present time in any 

 part of Scotland.
