species of Metacriniis found 
by the “Challenger” in the 
dredging S. ofTaam the “Si- 
boga” added three more 
species, no less than seven 
species of these magnificent 
forms thus occurring in this 
oneplace.To these I havead- 
ded two more,viz. a small,re- 
markably robust species of 
Rhizocrinus (?) and a large, 
reddish-brown form, appa- 
rently Democrinus Weberi 
(Dbderlein). One of the 
most interesting finds was 
two magnificent specimens 
of Dermatodiadema indicum 
Doderlein. In the speci¬ 
mens of this and related 
forms, brought to light by 
previous expeditions, the 
long curved spines are 
all directed upwards as a 
tuft, while the primary 
spines of the oral region 
are all lacking. Of the two 
specimens dredged here 
(PfStation 62) one especially 
was in perfect condition, 
hardly any of the spines 
being broken; they dis- 
closed the interesting faet 
that all the oral primary 
spines are provided with 
a curious hoof, recalling 
that of the Echinothurids. 
The spines all curve down- 
wards, those provided with
