Miscellaneous. Ill 



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. E. Gray, F.R.S. &c. 

 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 oi Pustularia rosea. 

 This is a mistake : Pusttdaria 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 graciUs (Jllman), from the Brick-Clay of 

 Seajield. By Robert Walker. 



Specimens of this Starfish were found for the first time, about a 

 year ago, in brick-clay near Dunbar. Prof. AUman 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
