cannot assent to M. Bibron’s referring this species to the genus 
Cistudo. These undersides evidently represent two distinct species ; 
and the upper figure of the two shows the very cross suture the 
existence of which Mr. Bell denies. 
The lower figures represent the sternum of Cyclemys orbiculata, 
with the lobes, especially the hinder ones, narrower than the open- 
ings in the thorax. 
The upper figure represents a species where the lobes are broad 
and rounded, and nearly as broad as the aperture in the thorax. 
It indicates the existence of a species which has not occurred to 
me, and to which the name of C. Bellii may be applied. Perhaps it 
is one of the specimens which he received from either Madras or 
Bombay ; for he says he has received them from those countries as 
well as from China; and I have not seen any specimens of the genus 
from either of these two localities. 
All the three specimens of this species in the British Museum have 
the lobes of the sternum narrow, like the lower figure. The figure 
of the shell with the animal in Mr. Bell’s work better represents 
Cyclemys Oldhamii than the depressed, flattened C. orbiculata of Java.

Notes on Pustularia rosea, Gray, and Hyalonema. 
By Dr. J. BE. Gray, F.R.S. &e. 
In Mr. Dallas’s translation of Prof. Schultze’s paper on Polytrema 
miniaceum (Annals, ser. 3. vol. xii. p. 411), it is stated that I have 
given to Polytrema miniaceum the new name of Pustularia rosea. 
This is a mistake: Pustularia is quite distinct from Polytrema. 
The latter genus is well known to me. Pustularia, if a Foraminifer, 
is nearly allied in external form to the genus Lepralia, and very 
unlike the massive Polytrema. 
Having my pen in my hand, I may observe that I cannot agree 
with Prof. M. Schultze in regarding the spicula in Carpenteria or 
Polytrema as parasitic and part of a Sponge, any more than I can 
agree with him and Dr. Bowerbank in regarding the fibres of Hyalo- 
nema as the spicula of a Sponge which is covered with a parasitic 
Zoanthus. 
Note on Ophiolepis gracilis (Allman), from the Brick-Clay of 
Seafield. By Roperr WAuKrER. 
Specimens of this Starfish were found for the first time, about a 
year ago, in brick-clay near Dunbar. Prof. Allman described the 
species at a meeting of the Royal Society of Edinburgh, in March 
last. The following remarks will show the condition of the Seafield 
specimens, and may assist in determining the species, if found in 
other quarters. 
None of the specimens have the disks sufficiently preserved to 
show clearly the arrangement of the dorsal plates ; and in one or two 
instances only can the form of the radial shields be made out. Their
