the flauks slightly convex in the former direction. The costm arc coarse, 
somewhat flattened, and straight on the venter, sliglitly sigmoidal and sharp 
on the flanks and lateral dorsal angles, and then hecome again straight and 
depressed on tire centre of the dorsum. Along each abdominal angle is a 
row of pronounced l)lunt tubercles, interrupting the course of every other 
costa. At a few points two costm unite at, or to assist in forming a tubercle. 
Tlie sulci or inter-costal spaces are concave. 
The test is much exfoliated, hut traces of the nacreous layer still 
remain. There are no vestiges of either septa, sutures, siphon, or camerae.
