7. S. punctata^ Desor. 



This is the only British species belonging to the section PeltasteSf Ag., 

 in which the sur-anal plate is placed between the vent and the odd 

 ambulacrum ; a specimen in the late Dr. Mantell's Collection has 

 the vent situated as in the normal Salenias. 

 Locality. — Green Sand, Farringdon. The specimen from the Kentish 

 Rag of Hythe, presented to the Mus. Pract. Geol. by H. B. Mackeson, 

 Esq., differs in no respect from Farringdon specimens of the same 

 size.

 Org. Rem. Co. Wilts, p. 7. (S. Woodward, 1835. Monograph of Brit. 

 Fossil Echinidae. MSS. in Mus. Pract. Geol.) 



Oblong, cordiform, inflated ; vertex moderately elevated, anterior sulcus 

 rather deep ; lateral ambulacra not impressed, pores sj^mmetrical ; primary 

 tubercles regularly distributed and equal in size above the lateral fasciole, 

 rather more crowded below, and larger on the under surface ; the upper is 

 densely covered with miliary granules, leaving annular spaces round the 

 tubercles; post-oral spaces elongated, covered with rather larger tubercles, 

 surrounded and divided by single rings of granules. Lon. ; lat. 2J ; 

 alt. 2 unc. 



Locality. — Upper Chalk, Norwich (Coll. J. King). "Chalk and 

 Flint, Heytesbury, Wilts." (Mus. Benett ; Brit. Mus.) 



Cardiaster Cotteauanus, D'Orb., Ter. Cret., pi. 830. 

 Locality. — Mr. Baily has recognized the occurrence of this species in 

 the Upper Chalk of Kent. There are two specimens from Dover 

 in the Museum of Pract, Geol., and one considerably smaller, and 

 somewhat different, from the Upper Green Sand of Warminster, 

 in the British Museum. 



Epiaster crassissimus, D'Orb., Ter. Cret., pi. 860. 



A specimen in the Mus. Pract. Geol., from the hard Grey Chalk of 

 Dover, only differs from D'Orbigny's figure in being more de- 

 pressed. Another species, from the Upper Chalk of Dover, in 

 the Brit. Museum, has extremely small and scarcely impressed 

 ambulacral petals ; the surface is perfectly preserved, but exhibits 

 no fascioles. 



Micr aster Mantelli, Forbes, MS. Morris's Cat., 2nd ed., p. 83. 



The specimens with this name attached do not differ in any respect 

 from those recognized as the young of M. cor-anguinum ; at this 

 age they are always very tumid, and the dorsal ambulacra are 

 scarcely at all impressed. 



Locality. — Upper Chalk of Dover and Kent.
