forms — TrochammincE of three or four species, and Endothyrce of 

 several species, but E. avunonoides was ver)^ abundant. This fine 

 stuff is best mounted in Balsam. The species is not abundant in 

 any one of the Northumberland Shales, but I have found it in the 

 finer shales of Ingoe when mounted in the way recommended. In 

 the example of the species that Mr. Brady figures, there are 157 

 segments. 



Horizon a?td Localities. — Scaur Limestone : Kendal Limestone 

 (Brady). Yoredale : Ingoe, Northumberland. Several localities 

 given by Mr. Brady. Hurst, North Yorkshire.

 This species is not abundant, so far as my experience goes, in 

 the Scaur Limestone series in either Scotland or Northumberland, but 

 in my Castleton material it is a very common form. In the Yoredale 

 series it is found in several localities. 



Horizo7i and Localities. — Scaur Li^iestone : Castleton, Derby- 

 shire, abundant; Redesdale, Northumberland. Yoredale: Four- 

 stones, Ingoe (Belsay, Coquetdale, Brady), Northumberland; Hurst, 

 Yorkshire. 



12 Endothyra crassa Brady. (Monog., p. 97, pi. v., figs. 15-17, 



Lower Bernicean.) 



13 Endothyra globulus Eichwald. (Monog., p. 95, pi. v., figs. 



7-9, Upper and Lower Bernicean.) 



14 Endothyra macella Brady. (Monog., p. 98, pi. v., figs. 13-14, 



Upper and Lower Bernicean.) 

 I cannot give these three species as found by myself in the 

 Northern Shales, unless I was to place (?) against my findings. I 

 have a few obscure forms that I thus place as E. globulus^ and a 

 doubtful E. crassa. I have both of the forms in my Castleton and 

 in my Hurst material, but even here they are rare. 



Genus STACHEIA Brady. 



Test normally adherent, composed either of numerous segments, 

 subdivided in their interior, or of an acervuline mass, sometimes 

 arranged in layers, sometimes confused. Texture subarenaceous, 

 imperforate. (H. B. Brady, Monog. Garb, and Perm. Foram.)
