On the Entomostraca of Berwickshire. 309 



prolonged to a point ; a few fine hairs at each extremity. This species 

 differs from C. deterta in being ventricose, and more arched in upper 

 margin ; and from C. Candida in being reniform, in not being ovate, 

 and in want of rigid hairs which beset that species. 



13. C. compressa. Nova species. Yetholm Loch. Shell round, 

 shaped, compressed rather narrower anteriorly than posteriorly; of 

 a grey colour, more or less deep ; semi-transparent j at either ex- 

 tremity beset with fine hairs ; in some specimens spotted as if little 

 pieces were hollowed out ; anterior feet provided with several long 

 bristle; eye large; antennae terminated by numerous long seta. 

 From the' flat compressed shape of shell, its motion through the 

 water is very much like that of some species of Lynceus. 



14. Lynceus harpce. Nova species. Pool on Beaumont Water, 

 and in Dunglass Pond. Shell harp-shaped ; ribbed longitudinally, the 

 ribs resembling the strings of the harp ; rounded posteriorly, sinuated 

 anteriorly, and terminating in a point projecting forwards ; antennae 

 four, long, nearly the length of the shell, each consisting of three 

 articulations, and terminated by three long linear setae ; shell smooth, 

 except anterior edge where it is sinuated, being there ciliated ; tail 

 serrated, terminated by two strong sets ; head rounded, and beak 

 blunt. Differs from L. truncatus. in sinuated anterior margin of 

 shell, blunt beak, and long antennae; in not being truncated on 

 posterior extremity ; in wanting the thirteen little teeth at the base ; 

 and in wanting the two thick and large upper feet : differs from L. 

 quadrangularis in shape, in sinuated anterior margin, in more dis- 

 tinct ribs, and in blunt beak. 



15. L. hamatus. Nova species. Yetholm Loch. Shell trun- 

 cated anteriorly, and ciliated ; upper part gibbous ; tail not serrated, 

 gibbous, terminated by two setae ; two upper feet large, and each 

 furnished at extremity with a strong claw or hook curved upwards ; 

 antennae of three setae each : approaches L. triijoneUus, but differs 

 from it in beak being blunted and stronger ; in tail not being serrated; 

 in wanting the strong pediform organ below palpi and above the feet ; 

 and in the upper feet having the strong hooks. 



The descriptions of the Entomostraca, and those of the new shell 

 Galathea neasa and fossil tooth are illustrated by three plates of 

 etchings, beautifully executed (we must tell it) by an accomplished 

 female member of the club. 



The results of the labours of this association, during the past year, 

 are thus shewn to be satisfactory in the highest degree. We hope 

 its members will persevere. They have instituted an admirable 

 school for themselves, and they must effect a great deal if they con- 

 tinue to persevere. We understand that similar clubs are now form- 

 ing upon the same plan in various counties. We wish them every 

 success.
