It occurs in two colours, yellowish-brown and white, 

 the latter is the smaller of the two varieties.

 A solitary specimen. 



Ammodiscus perversiis, n. sp. (PI. i, fig. 7). 



There is only one specimen in fair condition on the 

 slide, and this is the one figured, the remaining two being 

 fragments. They are evidently adherent forms. The 

 test is composed at its commencement of a simple coiled 

 tube, but later on the tube is much larger, and is coiled 

 over the earlier portion with the last part of the tube 

 bent back irregularly. The test is rough, of a light brown 

 colour, and is built up of fine sand grains. The under 

 surface is flat. 



Looking through some of the coarse material, I have 

 come across another specimen which is perfect ; but too 

 late to make a drawing of it, as the plates were already 

 set up. It only differs from the one illustrated in not 

 having the central portion of the test completely covered 

 up, and the end of the tube is not bent back on the upper 

 surface, but is doubled back at the side of the test.
