EEPOET ON THE HOLOTHHEIOIDEA. 
221 
rods cUid on6 transverse beam, the four rods not being combined as is usual 
— at the top, but terminating each in a simple point ; the smaller tables have 
the spire reduced to one or two spines. Buttons oval, commonly less developed, 
and only pierced with two elongate openings. 
Habitat . — Bowen (Ludwig). 
(Mus. Holm.) One specimen from the Fiji Islands. Length, 180 mm. Colour in 
alcohol, light dirty greenish inclining to brownish or yellowish ; the base of the 
pedicels and papdlEe surrounded by a dark brown ring; tentacles yellowish. 
Anus with five groups of papilla. The ventral pedicels of about the same 
size as the papHlte, and only a little more closely placed. A single Polian 
vesicle and madreporic canal. Calcareous ring agreeing with the figure given by 
Ludwig. Cmderian organs strongly developed. The usually very incomplete 
tables consist of a small irregular disk pierced with a few holes, and supporting 
a spire reduced to a single spine. In the pedicels and papillae the tables are 
more highly developed, having larger disks and a long spire built up of four rods 
and from one to five transverse beams ; these spires terminate in four simple 
points. Ludwig does not mention anything about the presence of such tables ; 
they possibly escaped his attention, otherwise the form examined by me is a 
new species, which, considering the very obvious resemblance, does not seem 
probable. The buttons are small and undeveloped in the body- wall itself, but in the 
ambulacral appendages they become larger, with six or more holes. The pedicels 
and papOlse have numerous elongate rods, either perforated only at each end and 
in the middle, or having a series of holes along each side ; moreover, the pedicels 
have bilaterally symmetrical perforated plates round the large terminal plate. 
The papillse have a very rudimentary terminal plate. Another specimen, 
belonging to the Godeffroy Museum, agrees in all respects with the above 
description, except in the circumstance that the spire of the tables never attains 
such a great length in the pedicels and papillae ; however, I often found these 
spires with two transverse beams. 
Holothuria fusco-cinerea, Jaeger, 1833 ; Semper, 1868. 
Habitat . — Philippine Islands (Semper), Navigator Islands (Semper), Celebes (Jaeger), 
Japan (Ludwig). 
A comparison of the description given by Semper with that of the preceding species 
will show that the two forms scarcely seem to be distinguishable from each 
other. Even Semper points out that the tables and buttons are much more 
developed in the ambulacral appendages. I examined one specimen, 220 mm. 
long, dredged at the Navigator Islands, and preserved in the Zoological btate 
Museum at Stockholm, which agrees in all respects with the specimen brought 
home from the Fiji Islands, and referred to Holothuvia curiosa. M ith regard to the 
colour, it differs slightly in the absence of the dark riugs round the base of the
