The first record of these Irish specimens was made, as 

 before stated, by McCoy in 1849, when he gave the following 

 description of the fossil * : — 



" Nodosaria fusulinafoi'mis. 



" Sp. Char. — Shell of two or more inflated, pyriform, easily 

 separable lodges, the first one having a small mucronate point 

 at its posterior end, and contracted to a very slender, short 

 neck at the anterior end, which joins the pyriform second 

 cell, which is also contracted to a similar minute neck in 

 front ; surface smooth. Length of individual cells averaging 

 1 line, width f of a line." 



McCoy also mentioned the very characteristic feature, well- 

 known in the Carboniferous Saccammina, of the segments 

 uniting in a moniliform series. He states that " The lodges 

 or cells are almost always found separated (from the minute- 

 ness of the connecting neck), which gives them the striking 

 resemblance to Fus^iiUna above alluded to ; I have heard^ 

 however, of several of them having been united in a line by 

 their little necks, and I have myself seen two thus united, 

 and the posterior cell not being a terminal one." 



The organism was found " in great numbers on the 

 weathered surfaces of the Carboniferous Limestone in the 

 parish of Shivey, Tyrone, in the North of Ireland." 



Although no figure was given with the description, it 

 appears to me to give the chief characters of the fossil as 

 regards the material available to McCoy, and in point of 

 fact the description could not be applied to any other foram- 

 inifer occurring in the Carboniferous Limestone. The chief 

 stumbling-block to the acceptance of McCoy's name seems to 

 be the comparison which he made between this form and 

 d'Orbigny's Nodosaria rudis and N. rugosa ; but it is very 

 evident to me that McCoy referred to the form of the seg- 

 ments, and not to the texture of the surface, which, indeed, 

 in his description he distinctly stated is smooth. 



This occurrence and description of the fossil were given 

 later in the same words by McCoy in another publication in 



1854 t. 



In 1869 J H. B. Brady recorded the discovery of similar 

 organismsaraongstCharles Moore''s foraminiferafrom "mineral 

 veins," and gave to them a generic name — Carteria. This
