with abrupt and conspicuous deep violet tips (station 12, Haiti, E. 

 5391; station 28, St. John, E. 5384, E. 5386). 



The spines vary somewhat in length, the longest sometimes almost 

 equaling the lesser diameter of the test (station 28, St, John, E. 

 5385), though usually they are considerably shorter. Occasionally 

 they are slender (station 28, St. John, E. 5385), and in one specimen 

 (station 17, Puerto Rico, E. 5393) they are swollen and club-shaped — 

 possibly a pathological condition.
