Test typically attached, with the earliest chambers coiled, quickly 

 followed by chambers in an irregular grouping rapidly covering the 

 early chambers, often with several layers; wall coarsely perforate 

 forming the apertures. 



The chambers conform to the general surface to which they are 

 attached. When the object is small, the chambers may completely 

 envelope it, or if small and cylindrical, they may group themselves 

 variously about it. If the surface of attachment is flat, the chambers 

 form a broad, generally flattened test.
