REPOET ON THE HOLOTHHRIOIDEA. 
195 
smooth or slightly spinous teeth. In addition to these deposits, Selenka mentions 
numerous perforated disks devoid of spires. Rosettes absent. The dorsal 
appendages are larger along the sides of the body, where they form a distinct row. 
Habitat . — Japan (Selenka, von Marenzeller). 
(Mns. Holm.) Two specimens dredged at Hong Kong, which may probably be 
regarded as typical. They attain a length of 200 mm. The dorsal papiUai 
are distributed aU. over the back, and some of them are situated on large 
conical processes, which have a length of about 17 nun. and a breadth at the 
base of 13 mm.; these processes form a simple row along each side of the body 
and a more irregular alternating double row along the dorsal ambulacra. They 
agree in all respects with those dredged during the Challenger Expedition, 
excepting that the deposits have almost exclusively the shape of perforated 
disks ; it is very rare to find any complete tables. 
Stichopus maculatus, Greeff, 1882. 
Spire of the tables terminating in fourteen to sixteen external and eight internal 
spines or teeth. Rosettes absent. Dorsal appendages in the shape of thick, high 
warts, between which smaller ones are placed. 
Habitat . — Rolas (Greeff). 
The arrangement of the dorsal papillae is not fully clear. 
Stichopus assimilis, Bell, 1883. 
Disks of the tables reduced to simple, uneven, or spinous rings, and the spire 
terminating in about eight (?) teeth. In addition to these deposits, flattened 
reticulated bars of very characteristic appearance. Rosettes absent. Dorsal 
papOae abundant and well developed. 
Habitat . — Angola (Bell). 
The species in question is too unsatisfactorily known to decide whether it is really a 
distinct species. The “ flattened reticulated bars seem to be nothing other 
than perforated rods or bars supporting the papillae or pedicels. A fuither 
examination wiR prove whether there exists any distinguishing character 
between this form and the preceding one. 
Stichopus hefersteinii, Selenka, 1867. 
Disks of the tables spinous in the margin ; spire terminating in twelve teeth. Rosettes 
absent. Four rows of warts with papillae along the dorsum, and scattered 
simple papiRae aU over the back. 
Habitai . — Acapulco (Selenka).
