a portion of the test, and are replaced by large clear tubercles or 

 beads. 



The variety occurs at the same Stations as the type, as well as 

 at a few others in both Areas.

Whilst a few more or less typical examples of these two species 

 occur in the Malay Archipelago, the greater mass is made up of 

 forms in which the characters of both are so intermixed that it is 

 useless to attempt to separate them. They both occur in con- 

 siderable numbers at several of the Stations in both Areas. 



For the occurrence of R. venusta, Brady names five South 

 Pacific Stations, 3 to 11 fathoms ; and off Calpentyn, Ceylon, 

 2 fathoms, or thereabouts. The ' Gazelle ' locality is off the Cape 

 of Good Hope, 50 fathoms.

This beautiful little form is very abundant at Station 17, and 

 occurs sparingly at other Stations in both Areas. The inferior 

 surface of the test is much more complex than would appear from 

 the published drawings, and is almost identical with that of 

 R. annectens var. concinna. The superior face is usually of a 

 delicate fawn colour. 



With respect to its general distribution, d'Orbigny found a 

 few examples in sand from Cuba ; Brady gives ' Challenger ' 

 Stations, Kandavu, 255 fathoms; and Humboldt Bay, Papua, 

 37 fathoms. He also states that it has been obtained from the 

 Straits of Banca, 7 or 8 fathoms ; off Java ; and off Penang. The 

 ' Albatross ' locality is not recorded.
