ge. Outline of same specimen if undistorted. 



100. Similar specimen from r. post, radius. X 2. Riks ^luseum. Gotland, (Dalhem d). 



lob. Basal view, showing RA in primitive position and other plates to first ray division in all 

 five rays. X 2.

 land (d or /) ; from r. post, radius. X ;• Riks Museum. 



lib. Same from 1. ant, radius, malformed and injured by parasites such as Stylifer, or

lie. Basal view, showing IBB within ring of BB, and RA. X 2. 



lid. Same from r. post, radius, showing RA in primitive position. X 2. 



III?. Detail of 1. post. IIBr 3 and 4, showing pustulose surface ornamentation. X 3- 



11/. Part of 1. post. IIBrn, showing surface ornament in greater detail. X 8.

120. Fragment from Faro, containing part of two rays from the first axillary to IVBr, show- 

 ing injury by boring parasites. X 2. Riks Museum.
