i897-] Chaster. —Bredgmo- q^ Bally castle, Co. Antrim. 125 



IWontacuta donacina, Jeff. — Two valves from Church Bay. An 

 excessively rare species. It was obtained by the "Porcupine" 

 Expedition of 1S69 in Lough Swilly, 3 — 13 fathoms. 



Homalogyra polyzona (Brus. Mss.), Bucq., Dautz., & Dollf. (Moll. 

 Mar. du Rousillon, p. 325, pi. 37, fig. 32). I have hesitatingly 

 admitted this to rank as specifically distinct from H. atomns, Ph. 

 Whether a variety or species it is an addition to our British fauna. 



Odostomla truncatula, Jeff. One of our specimens, when carefully 

 examined, is seen to contain the operculum and remains of the 

 animal, thereby affording conclusive proof that the species still lives 

 in the district. Like Galeonima Turtoni, it is known in the living 

 state from southern localities only, and but for the observation just 

 recorded it might be considered an equally doubtful denizen of the 

 Antrim sea. 



Adcorbis Imperspicuus, Monterosato. 



Adeorbis unlsulcatus, Chaster. These two species have been 

 generally overlooked owing to their microscopic size. The latter I 

 have described and figured in the current number of the Journal of 



Conchotomy. 



A PROPOSED GEOI^OGICAIv PHOTOGRAPHIC SURVEY 

 OF THE COUNTIES OF DUBININ AND WICKI.OW. 



BY PROF. GRHNVIIvLB A. J. COLB, F.G.S. 



Now that the excursion-season of the Dublin Naturalists' 

 Field Club is about to open, it seems desirable to organise a 

 photographic survey of the counties that lie nearest to our 

 homes. Very little has been done in the way of recording the 

 features of our wilder landscapes, or indeed of any district 

 remote from Kingstown Pier, or the Esplanade at Bray. Mr, 

 W. W. Watts, as Secretary of the Committee of the British 

 Association in charge of Geological Photographs, has brought 

 the matter home to us in a recent number of the Geological 

 Magazi7ie, where lie points out the excellent work done in the 

 north of Ireland, and remarks ** that such districts as the 

 Wicklow Mountains, the beautiful tract of lyimerick, the areas 

 of ancient rocks in Galway and Mayo, and the Carboniferous 

 and Old Red Sandstone rocks of Kerry, are all, literally, 

 awaiting development."
