the sutures is in the hollow between the ridges. The species 

 partakes of the characters of both D. patclliformis and D. taber- 

 nacidaris, but is distinct from either. 



The examples are from Station 31, in Area 2.

This form is badly represented in the Malay Archipelago, the 

 examples being few and insignificant. It has been noticed only 

 at Stations 2 and 6, both in Area 1. 



It is recorded by d'Orbigny from the Islands of Cuba and 

 Martinique ; by Brady from four points on the coast of Australia, 

 at depths of from 2 fathoms to 155 fathoms ; and by Egger from 

 West Africa, Mauritius and Western Australia from 37 to 225 

 fathoms.

Of this rare form there are some rather feeble specimens from 

 a few Stations in both Areas. 



The ' Challenger ' localities given by Brady are : Nares Harbour, 

 Admiralty Islands, 17 fathoms; and off Booby Island, south of 

 Papua, 6 to 8 fathoms. To which I can add Eaine Island, 155 

 fathoms, from specimens in my own collection. 



The sole ' Gazelle ' Station is Kerguelen, 57 fathoms.

This variety differs from the type in several respects ; the 

 superior face is flatter, and the inferior more convex ; the 

 chambers are more inflated, and the peripheral edge less acute ; 

 the aperture is indistinct, and the radiating lines on the umbilical 

 region are not apparent. 



This is one of the characteristic forms of the Malay Archipelago,
