8 DR JOHNSTON'S ADDRESS. 



have attracted our attention : I mean the butterfly tribe. Of this, 85 

 species (including 1 1 that perhaps may properly be considered as varie- 

 ties) have been ascertained to be natives of Britain ; and, of these, we 

 have, in Berwickshire, only 16 distinct species, or somewhat more than 

 one-fifth of the whole. Four belong to the family Papilionidae ; nine to 

 the Nymphalidae ; and three to the Lycaenidae l . None of the species 

 are esteemed rare by experienced entomologists ; but, in Berwickshire, 

 I never observed the Hipparchia Semele, until on our visit to St Abb's 

 Head in July last, where we found this fine active insect in great profu- 

 sion. The more common Hipparchia ^geria, also, I have seen in one 

 locality only in this county, viz. on the wooded banks of the Eye, below 

 Ayton House, where it may be captured in the months of June and July. 

 The Pontia cardamines is likewise a local species with us ; it very rarely 

 occurs in the neighbourhood of Berwick, but appears very soon after 

 passing the village of Paxton, on the road to Swinton, and abounds all 

 along that low tract. It is also common on the road between Swinton- 

 Mill and Coldstream ; but I have not noticed it elsewhere in Berwickshire. 



Exannulosa. Communications relating to the exannulose inverte- 

 brate tribes have been made as yet only by myself, but I have now a 

 zealous co-operator in our Secretary, whose situation is peculiarly favour- 

 able for the investigation of these intricate and vastly curious creatures, 

 among whose multitudes, it may be truly said, " we meet with forms 

 and structures as varied and unexpected as if they had been the tenants 

 of another planet." A collection of the zoophytes of the coast was ex- 

 hibited at an early meeting, which I have since described at length in 

 the Transactions of the Natural History Society of Newcastle ; and I 

 flatter myself that no department of the natural history of Berwickshire 

 is now so well known as this, in reference to species : their habits and 

 economy require for illustration a person of more uninterrupted leisure. 

 Our Actiniae, or animal flowers, on which I read a separate paper, are 

 remarkably interesting. I know no marine worm that for beauty and 

 elegance can be compared with the Actinia plumosa ; and such of you 

 as had the opportunity of seeing the specimen that I preserved for some 

 time alive, will recall with pleasure the splendid spectacle. Actinia 

 Tuedia was still more interesting, to me at least, for the species was new 

 to naturalists, and, fortunately, possessed characters that distinguished it 

 decidedly from every other. The Actinia coccinea and viduata of Miil- 

 ler are also denizens of our shores ; but the first was considered as a 

 smooth variety of the senilis, and the other a small streaked variety of 

 the equina.
