1 6 Address to the Members of 



sence of these tubercles ; in the former the lateral line is said 

 to be tuberculated above the pectoral fins, in the latter it 

 is said to be smooth : but here we have a specimen which, 

 when alive, exhibits the character of the Jago; when dead, 

 that of the trifurcatus ; and hence I am induced to think that 

 both are the same animal, having the tubercles more or less 

 prominent and obvious according to the leanness, or other 

 conditions, of the body. 



[Insects."] — Since no communication has been laid before 

 us relative to the entomology of Berwickshire, it is beyond my 

 province to make any remarks on the subject ; but you may 

 permit me to notice one family, too beautiful, too generally 

 distributed, and too obtrusive, not to have attracted our 

 attention : I mean, the butterfly tribe. Of this, 85 species 

 (including 11 that perhaps may properly be considered as 

 varieties) 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 Lycse'nzd^ *. None of the species are esteemed rare 

 by experienced entomologists; but in Berwickshire I never 

 observed the Hipparchi« Semete, until on our visit to St. Abb's 

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

 great profusion. The more common Hipparchia JEgeria, 

 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 

 soon after passing the village of Paxton, on the road to Swin- 

 ton, 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. 



[_Exannulbsa.~\ — Communications relating to the exannu- 

 lose invertebrate tribes have been made as yet only by myself, 

 but I have now a zealous cooperator in our secretary, whose 

 situation is peculiarly favourable for the investigation of these 

 intricate and vastly curious creatures, among whose multi- 

 tudes, it may be truly said, " We meet with forms and struc- 

 tures as varied and unexpected as if they had been the 

 tenants of another planet." A collection of the zoophytes of 

 the coast was exhibited at an early meeting, which I have
