belongs to the earlier genus Hippothoa, Lamarck, and 
coccinea is the type of the earlier genus LHscharoides, 
Lamarck, as settled by Gray. Gray instituted a genus 
Escharella, to which he removed variolosa and immersa; 
and Hincks established three new genera, in which he placed 
the three remaining species Membraniporella nitida, Micro- 
porella ciliata, and Smittia trispinosa. We have seen that 
Johnston’s L. hyalina has its place in the earlier described 
genus Hippothoa; the second species in his work was 
Lepralia nitida, and I would suggest that that species be 
regarded as the type of his genus. 
Genus Lerraia, Johnston. 
= Membraniporella, Hincks (nee Lepralia, Smitt, nec Lepralia, Hincks)- 
Type, Lepralia nitida, Johnston.

Nordkyn (Nordgaard). Ihave not myself seen any speci- 
men of this species from Norwegian or Arctic seas ; nor 
would it appear that Smitt had met with it, since the only 
localities he gives are Britain and Bahusia. The record of 
this species, therefore, in East Finmark extends our know- 
ledge of its range very considerably. 
Genus GEPHYROTES *. 
Type, Gephyrotes (Cribrilina) nitido-punctata, Smitt. 
Bars narrow, and widely separated more than halfway to 
the central line, leaving broad open intervals between them, 
then bending to either side they unite with the adjoinmg 
bars forming thus a regular arch, beyond this are large 
lateral lacunes, few in number, no median lacunes usually 
developed. The foremost bar but oneis forked, the lower limbs 
of the opposite forks uniting transversely across the zocecium, 
the upper limbs directed upwards and forwards and then 
uniting, thus leaving a large opening below. Oral bars large 
and solid, resting, as regards tbeir central portion, on the 
upper limbs of the fork behind, and in front forming the 
lower lip of the oral opening, and at their sides below two 
large openings, but these are not equal in size to the central 
opening already mentioned; the bridge thus formed by the 
foremost bar and the front members of the second bar is 
projected outwards and overhangs the rest of the zocecium 
in such a way that the large central opening is often con- 
cealed from sight when the zocecium is viewed from the front.
