Descjiidion. — Test elongate, compressed, early portion spirally 

 coiled, later portion uncoiled and straight but compressed 'through- 

 out, chambers poorly marked, sutures indistinct; wall coarsely 

 arenaceous with much cement, aperture irregular, usually a small 

 opening at the end of the chamber. 



Length, up to 1.5 mm. 



Distribution. — Williamson's type specimens were from Skye. 

 Brady gives the following localities "not uncommon amongst the 

 islands on the west coast of Scotland at depths of 30-60 fathoms" 

 (.55-110 meters), two Porcupine dredgings from the coast of Ireland, 

 in 90 and 370 fathoms (165 and 677 meters) and from off Valentia, 

 Jrelaml. Wright's specimens were from the southwest of Ireland 

 7-53 fathoms (13-97 meters) with a single very small specimen at 

 345 fathoms (631 meters). Heron- Allen and Earland record it as 

 common in the Clare Island region off Ireland and off western 

 Scotland. 



It has not occurred in the Albatross material from the western 

 Atlantic as far as I have seen and it is recorded neither by Goes nor 

 by Flint from the same material. 



In my own collection I have material from the second cruise of the 

 S. S. Protector h\ 100 fathoms (183 meters), northwest of Belfast 

 between Belfast and Port Patrick and from the Lord Bandon off 

 S. W. Ireland in 38-44 fathoms (69-80 meters). The figures given 

 by Goes and here referred to are very typical but as Goes included 

 A. foliacevm also, the records are obscure. 



The species is evidently common in comparatively shallow water 

 off the coast of northern Europe but not from the western Atlantic as 

 far as the material examined shows.
