Three Kings Isl., 65 fms; hard bottom. 
Further I have received through Mr. W. R. B. Oliver a few 
specimensfrom theCooksStrait,120fms.,collected by Mr. H azelwood. 
To the very careful 
description of this spec¬ 
ies given by Farquhar 
I have but little to add. 
On the other hånd, it 
may be of importance 
to give a pair of figures 
ofthespecies,Farquhar 
nothaving published any. 
The tooth-papillæ, 
which are rather excep- 
tionally numerous for an 
Ophiocoma, are arranged 
above in 6 irregular trans¬ 
verse series; inwards in 
the mouth they gradu- 
ally decrease in numb- 
ers, only the lateral 
series on each side con- 
tinuing until they meet 
the teeth, which are 
squarish, provided with 
an enamel cap, as usu- 
ally in Ophicoma. There 
are 7 tooth papillæ in 
the vertical row of the outer series, and below the e papillæ (or 
above them, if we place the animal in its natural position) 2—4 
teeth. The mouth is thus very deep. The outer series of the tooth 
papillæ are longer than the inner ones, the chewing surface of each 
jaw thus being concave. — The side mouth shields may be excluded 
from . the adoral edge of the genital slit (Fig. 9.i). Regarding the 
shape of the ventral and dorsal plates I may content myself with 
referring to the figures. The spines may be in the number of 8
