Figg. 140 — 143: is the typical Textul. ugglutinans d'Oeb.; it cannot properly be 

 distinguished from Textul. sagittula Defk. 



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- 

 ctinahnn etc. Rss. It is sometimes very mucli flattened out and has then again been 

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

 form are many and 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. confeci Williams.); sometimes Avith 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. 157 — 158: nearly of the same shape as the preceding.
