Figg. 140 -143: is the typical Textul. agglutinans n'ORB.; it cannot properly be 

 distinguished from Textul. sagittula DEFR. 



Figg. 144 146: a very compressed and often serrated form; it has received many 

 names: Textul. carinata, Maria, cuneiformis D'ORB., Plecanium serratum, spinulosum, pe- 

 ctinatum etc. Rss. It is sometimes very much flattened out and has then again been 

 loaded with a number of new names. The gradations between this and the conical 

 form are many arid altogether too insignificant to be distinguished from each another 

 even by varietal-names. 



Figg. 147 149: its first step towards the conical form. 



Figg. 150 -158: different gradations of Textul. sagittula into the conical form 

 {Textul. cuneiformis var. conica WILLIAMS.); sometimes with convex, another time with 

 flat basis. 



Figg. 150 151: small specimen. 



Figg. 152 154: very developed with a chalky texture. 



Figg. 155 156: smaller specimen with distended base, and nearly circular in 

 transverse section. 



Figg. 157158: nearly of the same shape as the preceding.
