Permian blastoid from Timor - Sundablastus?

[Mochaccino]

Hello,

 

This specimen was labeled as "Sundablastus?", a Permian blastoid from Timor, Indonesia. It's about 2 cm long.
 

 

I tried looking it up and could find no images nor Wanner's original description of the genus in 1924. All I could find was this attached article Fay 1961 "Blastoid Studies" with just the following bit of text describing Sundablastus, which does seem consistent with my specimen:

 

"A trend in this group is reduction in length of the spiracular slits to form small round slits on the summit and shape of the calyx becoming spherical (Sundablastus)"

 

Can anyone confirm the ID or provide images that I can reference? Thanks.
