Leda pusilla, Jeff. i^Proc. Zool. Soc, 1879, p. 580, pi. xlvi., fig. 6). — 

 A perfect though dead specimen and two valves, all of small size. 

 The finding of this species in shallow water is of great interest, 

 for though it occurred in the " Porcupine " Expedition dredgings 

 of 1870, S. and S.W. of Ireland, the stations are all in deep 

 water (257 to 690 fathoms) and are outside the southern limit 

 assigned by the Rev. Canon Norman to the British area. It is 

 therefore an addition to our fauna. 



Galeomma TurtonI, Eds. (Zool. Journ.) — A broken valve was all that 

 was found to represent this species. 



This occurrence of this characteristicall}- southern form so far 

 north is remarkable, but it remains to be proved whether it still 

 lives in the district, or is extinct. Professor G. O. Sars in the table 

 appended to his " Bidrag til Kundskaben om Norges Arktiske 

 P'auna" (MoUusca regionis arcticse Norvegiae) has included this 

 species amongst those whose record in Norwegian waters rests upon 

 good authority, though its rarity there is attested by the asterisk 

 prefixed to the name, indicating that he has not himself met with it. 

 A not unlikely explanation of its occurrence in these northern 

 localities is that valves have been washed from some of the raised 

 beaches. My late friend, Mr. David Robertson, notes an equally 

 characteristically southern vSpecies — Trochus li)ieaius — as moderately 

 common in the raised beach at Cumbrae (Trans. Geol. vSoc. of 

 Glasgow, I875, PP- I95» iQ^)- ^ have no opportunity of ascertaining 

 whether Galeomma is known to occur in the raised beach at Portrush, 

 or in others.
