    Saloon. No. 33. Spatangus Cor. Marinum. This appears to be a variety of Cor . Anguinum Anglicum of Klein. The characters of this shell are its being cor- Left dated, and more or less oblong; the base, in some flat, and in the superior, Apartment. ^'^'^ fewer and smaller granulae. The back is convex, and divided into five are«e, by as many grooved ambulacra, formed by four rows of pores, connect- Fossils. transverse lines, each two rows uniting at the end of the grooves. Two of the ambulacra, the shortest, are directed obliquely towards the nar- Case G. ''^ truncated extremity; two others, longer, pass obliquely towards the broader end; and the fifth passes straight to the mouth, forming the dorsal groove Along the middle of the crppcisite part, a keeled edge passes direct- ly to the anus. The vertex is perforated by four large pores; the mouth is re- niCorm, the upper lip triangular, and extended over the lower; the anus is round, and placed in the upper margin of the acute extremity. From the ani;i a slight depression passes to the lower margin; at each of the angles of wh'ch is a protuberance, surrounded by a broad smooth surface. This spe- cies is found in many part-s of Europe, particularly in Germany and England; are the most frequent fossils in the chalk-pits of Kent and Essex, and frequent- ]v f.iund fille'' wi'h flint. They are the Echinites Cordati Vulgares of i^hwyd. Lithoph. fig. 364, and 967. No. 34. hpatangus Lacunosus, Klein. Is of an oval form; its upper surface gibbous, and its under rather convex. At the vertex are cwo, or according to MuUer, four puncta. From the vertex immediately proceed four deeply obtuse ambulacra, with angular margins; within the grooves are four rows of pores, connected by transverse lines. The two posterior ambulacra, directed towards the narrowed part of the shell are shortest, being sometimes merely twci deepish fossulae; between the two anterior ambulacra is disposed another deep groove, which is also beset with strise and puncta. On each side of the shell, are several gradually rising prominences; from which pass, in different directions, sever.d intercurrent lines, on which minute granular tubercles are very thinly disposed; whilst the general surface is covered with tubercles of »ather a larger size. The mouth is small, and nearly round; the anus is round, and placed in the upper margin of the narrower, and apparently trun- cated termination of the shell Erom some peculiarity of structure, the spe- cimens we have met with are always apparently distorted. The recent shell with its spines is figured in the 6th vol. of Encydopedie Francois, plate LIX. fig. 4. This fossil is from Malta, No. 35. Echinites Pyriformis, Leske. The shell is ovate, gibbous, and ra- ther acute at one end; the base flat. On the back originate five porous, sub-^ petalous. ambulacral bands, which reach to the periphery: a carrinated line divides the back of the shell as it were in two parts; in the middle of the base is the round sub-pentagonal mouth, furnished with five prominent lips, between each of the two prominent lips a double series of pores unite, form- ing a five-rayed star round the mouth. The anus is round, and placed in the upper part of the acute extremity of the shell. These fossils principally oc- cur in St Peter's Mount, Ma;strichf. No. 36. A very interesting and beautiful fragment of a cast of an Echinus in rich amber-coloured Calcedony; its country unknown, as well as the spe-. cies to which it belongs, it appearing tp have been a bowldered fragment. No. 37. Various fossd spines of Echini, some of which are embedded in flint. These are prinoipally of the Cucuraerinx species,.from the chalk-pit of Kent and Essex. The specimen in chalk marked C. is very rare, and ap- pears to have been a spine of the species Sudes Villarum, These.spines luv often been mistaken for Belemnites, and arranged as such; but the small anr.u larmark at one end, shews indisputably its point of articulation. Case H. Case H. Contains thirty-six specimens of fossil substances from M.tstricht Their peculiar form and structure, so diifercnt from those of other district render it exceedingly difficult to determine in what genus the greater part ^hem should be ylaccd^ Whether they should be arianged among the madr?
