able to figure here. 
The oral shields are stated by Farquhar to be circular, usually 
with a slight peak within. I have found a considerable variability 
in regard to the shape of the oral shields, the nearly circular form 
being met with more rarely. The usual form I find to be that with 
a slight restriction near the outer edge (Fig. 20,i). The adoral shields 
sometimes join completely proximally to the oral shield; they may 
prolong outwards so as to reach the genital slit, but equally often 
they have no such prolongation (Fig. 20.i). The outer mouthpapillæ 
I have sometimes found to be bifid. The arms, which are very 
long and siender, ca. 15 times the diameter of disk, are some- 
what flattened and slightly increasing in width, thus being some- 
what more siender close to the disk than farther out, and then very 
gradually tapering towards the end. The dorsal plates may vary
