Wright — Foraminifera of North-East of Ireland. 151 



To my friend Mr. H. B. Brady, F.R.S., I am much indebted for the kind 

 assistance rendered me in identifying the critical species ; and to my friends Mr. 

 W. Gray, M.R.I.A. ; Mr. S. A. Stewart, F.B.S.E. ; and Mr. W. Swanston, 

 F.G.S., for the valuable help they gave me in supplying material for examina- 

 tion, from various localities not visited by myself. 



The following notes on some of the forms found may be of interest : — The 

 Lagtnce were among the most interesting, and occurred in great abundance, 

 both in numbers and species, in the Estuarine Clay at Limavady Junction. 

 All our recent British species of Lagena, except crenala, were found at this place. 

 Trigonal varieties of our flat Entosolenian Lagenas were very numerous. All 

 the British forms had here their three-sided representatives — viz., marginata, 

 lucida, ornata, lagenoides, and pulchella (small), as well as two examples of a 

 four-sided marginata. These, though curious and interesting, are after all 

 but subvarietal modifications of the types, not even ranking as good varieties. 

 I have recorded in the list trigono-marginata, (trigono) oblonga, and trigono- 

 ornata, as being the best and most characteristic of these varieties. 



Lagena striato-punctata, P. and J. 



This species, now so rare in British water, is abundant in the Estuarine 

 Clay at Magheramorne and Limavady Junction ; also, a variety very small in 

 size, and having only six longitudinal ribs.

 run in longitudinal lines.

Lagena Jeffreysii, Brady MS. Wright, Rec. Forams. of Down and 

 Antrim— Belfast Nat. Field Club Rep., Appendix 1876-7, PI. IY, fig. 15. 



A few examples of this rare Lagena have been met with in the Estuarine 

 Clay at Limavady Junction.

 Quart. Jour. Micr. Sci., Vol. XX, New Series. 



Not unfrequent in the Estuarine Clay at Limavady Junction. This species 

 has only within the last twelve months been recorded as recent on our coasts.
