T. mammiUata (M. & Tr.). Locality unknown. Pedicellarise 

 absent on type (t. Perrier). 



cc. — Pedieellariae are present; their blades are higher than broad, 

 usually spatulate or spoon-shaped. Only two to three pairs of dorsal 

 marginal plates are in contact medially.

 946 to 1105 meters. 



In this species there is a regular row of spatulate pedicellarite on 

 the row of plates next the adambulacral series.

Pedicellariae small, numerous ; they occur on the actinal, adambu- 

 lacral, abactinal, and on both series of marginal plates. In the type 

 some of the marginal plates are naked m the middle, perhaps acci- 

 dentally rubbed. Three of the dorsal marginal plates are in contact 

 medially.

 nal and both series of marginal plates.

A large specimen, from off Halifax, N. S., has the following char- 

 acters : 



The inner adambulacral spinules form a simple marginal row, with 

 three or four spines on each plate, of which the proximal is smaller
