180 Wright — Foraminifera of South Donegal. 



house was somewhat more sandy, and yielded a larger number of species. 

 Bulimina, Bolivina, and Cassidulina were the characteristic genera at both 

 places. The two gatherings taken off Slieve League differed scarcely in any 

 particular. 



I have taken advantage of the present opportunity to record (under 

 column 8) a list of species found in a dredging taken off Portstewart, by my 

 friend Mr. James Wright, and kindly sent by him to me for examination. 



I am deeply indebted to my friend Mr. H. B. Brady, F.R.S., who, with his 

 usual kindness, has examined and named the critical species ; as also to my 

 friend Mr. W. Swanston, F.G.S., for the accurate and artistic drawings of the 

 Foraminifera which accompany this memoir. 



I append a few remarks on one or two of the forms of more special interest. 



Haplophragmium glomeFvATtjm, Brady. (Plate viii, figs, 1, la.) 



Lituola glomerata, Brady, 1878, Ann. and Mag. Nat. Hist. Ser. 5, vol. 



1, p. 433, PI. xx. fig, 1 a, b, c. 



This simple little Haplophragmium is abundant in Killybegs Harbour. It 

 was also dredged last year by Mr. David Robertson, F.L.S., off the Isle of Skye, 

 being the first record of its occurrence in British waters. The Irish examples 

 are not so coarse in texture as the type specimens from the Arctic seas, 

 figured by Mr. Brady, 



Ammodiscus Shoneana, Siddall. 



Trochammina Skoneana, Siddall, 1878, Proc. Chester. Soc. Nat. Sci., part 



2, p. 46. 



A few examples of this pretty little Ammodiscus were found off Killybegs 

 Harbour. It has hitherto been only met with in the Estuary of the Dee, by 

 Mr. J. D. Siddall ; and in Belfast Lough, by Dr. Malcomson. 



Gaudryina filiformis, Berthelin. (PI. viii. figs, 3, 3a, 36.) 



Gaudryina filiformis, Berthelin, 1880, Mem. Soc. Geol. France, Ser. 3, 

 Vol. 1. Mem. No. 5, p. 25, pi. 1, fig, 8, a— d. 



An elongated sandy Gaudryina, with later chambers subquadrate. Often 

 in a fragmentary state, the loose sandy texture of its test making it liable to 

 be easily broken. Well-grown perfect examples are not unfrequent off Killy- 

 begs. It has been found at many stations round our Irish Coasts; also off 

 Skye, by Mr. Robertson.
