Remarks. This species appears nearest to Calthropella i^'eo- dioides (Carter), from which it differs for the extreme tendency to de- formity of its calthrops, for its oxeas three times as long and having peculiarly elongated and flexuous points, for the irregularity of some of its asters. In the same time, it is opportune to note that '1'opsknt (1892a: PI. 8, Fig. 9) figured for (\ simplex Sollas a small, irregularly massive aster cjuite equivalent to those present in my specimens. It is also worthy of attention that a calthrop bearing a rounded rudiment.
