B. Deposits— Tables together with Buttons. 
I. Ambulacral appendages— pedicels alone ; or pedicels on the ventral surface and papillse 
on the dorsal, the latter being often very like the former. 
1. Buttons smooth, oval or elongate, nearly akvays ivith three pairs of holes, 
exceptionally loith more or fewer. Spire of the tables as a rule made 
of fovr rods and one transverse beam ; exceptionally more rods and 
beams present. 
a. Disks of the tables smooth, without spines on the margin. Number of tentacles 
typical, twenty. 
(1) Ventral pedicels arranged in three more or less distinct longitudinal series.

(Mus. Holm.) Two specimens from unknown locality, and one 110 mm. long from 
Pelew Islands. Professor Mobius of Kiel has also kindly sent me a small 
specimen, about 45 mm. long, dredged at Mauritius. In the small specimen 
from Mauritius, which is probably young, the pedicels are placed in three double 
or alternating rows on the ventral surface, an arrangement which is not so distinct 
in the remaining forms. Even the small dorsal papillpe do not always seem to be 
placed in very distinct rows. Colour of the smaller specimen — auburn, with 
the ventral surface, the pajjillse, and a space round them paler. The large 
specimen from Pelew is dirty yellowish-white, sj)eckled with brown or gTeenish- 
brown on the back. Mouth surrounded by some small papdla.'. The disks of 
the tables are slightly undulated on the margin. The symmetrical or sUghtly-
