THE FORAMINIFERA. 49 



Shepheardella toeniformisj Siddall. 



Siddall, Quarterly Journal of Microscopical Science^ April, 1880, 

 pi. XV, xvi. 



The ''test" of this remarkable form, as in the last species, 

 is only membranous ; and this may account for the fact that 

 no record, except the above, has ever been made of its appear- 

 ance in British or foreign seas. The only way to obtain it 

 is by searching on the sides of bottles in which have been 

 kept the finer marine Algae and Hydrozoa, &c. From such 

 a source I obtained last year, in examples from Colwyn Bay, 

 a specimen which measured two inches in length when 

 stretched out on the bottle side. It looked just like a very 

 delicate pale yellow hair, from each end of which was 

 extended a ramifying network of vigorous pseudopodia. 

 This specimen, after examination, I mounted and still have 

 in my cabinet. 



Habitat. — On Hydrozoa, &c., dredged in Colwyn Bay. 

 Frequent in spring at Tenby.

Although generally distributed among shore Foramini- 

 fera, Gi'omia is, so far as my observation goes, more at 

 home in brackish water than in the sea. In the tide pools 

 left upon the muddy shore of the Dee, near Holywell, I have 

 on several occasions found both species liviiig in great abun- 

 dance, in company with numerous other very varied forms. 

 A careful scraping of the surface of the mud at the bottom of 

 such pools is sure to yield, after resting awhile in a bottle of 

 sea water, a rich harvest of living Khizopoda. If the sun 

 has been shining upon the pool for a short time, so much 

 the better, as thin flakes of mud then rise to the surface of
