This seems to be the southern representative of the preceding species but 

 is easily distinguished by the broader, higher test and the longer, narrower 

 petals. The Challenger specimens were all from the southern coasts of Chile. 

 I think the specimens recorded in the Challenger Report from Kerguelen are 

 the following species, while that from Station 146 at a depth of 1375 fms. needs 

 further examination. The Albatross made three dredgings off southern Chile 

 in depths exceeding 1000 fms. and moseleyi did not occur in any one of them, 

 while of the nine dredgings at less than 700 fms., this species occurred in seven.
