This specimen is larger than the type, the interlobular furrows are deeper and the 

 areolse are more subdivided. There are two grooves between the posterior margin and 

 the gastric region ; the posterior lobule thus formed projects forward at the middle ; the 

 lobule in front of it is broken in two at the middle ; the cardiac lobule has a small lobule 

 separated from it at either end; the inner branchial lobule is subdivided into three 

 tubercles. The median sinus of the front is broadly U-shaped and the lobes either side 

 are correspondingly narrower than in the type.
