Of the above, Cardium edule, Tellina balthica, and Turritella terebra occurred 

 most frequently. Of Corbula and Tellina complete valves were obtained ; 

 one valve of Tellina has its rosy-red colour beautifully preserved. The 

 one specimen of Nassa was complete ; the species has not yet been deter- 

 mined ; it is not recent British. Of Lucina and Mya the epidermis was 

 still adhering. 



Brown Boulder Clay (separated from the underlying 

 mass of the Boulder Clay by a bed of gravel). — In this bed the 

 shell-fragments attain their maximum, the clay being thickly studded 

 with them. The species identified were — 



(N.) Ostrea edulis. (N.) Tellina balthica. 



N. My til us modiolus. (N.) Mactra solida ? 



Bxt. N. Lcda pemula. — Saxicava rugosa. 



— ■ Cardium edule. — Corbula gibba. 



(N.) Astarte sulcata, var elliplica. (N.) Mya truncata ? 



(N.) Cyprina islandica. — Turritella terebra. 



(S.) Tapes virgineus . — Buccinum undatum. 



Corbula was the only shell of which a complete valve was obtained. 

 Cardium, Tellina, and Turritella, were, as before, the commonest species. 



Contorted Drift. — The fauna of this bed was only very cursorily 

 examined. Shell-fragments are frequent, but by no means so well pre- 

 served as in the boulder clay. Cardium echinatum, Cyprina islandica, Tellina 

 balthica, and Turritella terebra were the only species identified, but further 

 investigation will, no doubt, add largely to the list. Cardium echinatum 

 and Cyprina islandica were found to occur also in the gravels that gener- 

 ally form the upper portion of these beds, and within a couple of feet of 

 the top of the section. 



THE HYMENOPTERA-ACUEEATA OF COURTOWN, 



CO. WEXFORD. 



BY H. K. G. CUTHBERT. 



The pretty village of Courtown is the centre of a district of 

 considerable interest to entomologists. The great variety of 

 the landscape, upland and lowland, the abundance of wood, 

 and the extensive ranges of sand-hills which fringe the 

 coast, are all favourable to the insect-hunter. Hence various 

 rarities have from time to time been added to the aggregate 

 of our local fauna by collectors in this region. The following 

 list of Aculeate or stinging Hymenoptera is the result merely 

 of a few days' collecting in August, '92, and a couple of weeks
