 flattening in this region. Lisuakerry. Dublin Museum of Science and Art (Geological Survey

Fig. 2 a. Lateral view of the cast of a large specimen, showing two distinct constrictions. 2 b. 

 Peripheral view of the same. 2 c. Sutures of the same ; the last three septa ; the peripheral lobe is 

 too narrow. Clane. Dublin Museum of Science and Art. (Page 165.) 



Fig. 3 a. Lateral view of a cast of typical shape. 3 b. Peripheral view of the same, showing
