The series in Dr. Grindiod's museum, as partially exhibited on Wednes- 

 day, commence appropriately with a fine group of these most ancient rocks ; 

 for though themselves azoic, and as we believe pre-zoic, they form the most 

 natural introduction to the superjacent fossiliforous strata. 



Immediately upon the syenite rests what is locally known as the Holly- 

 bush Sandstone. For a long time it was not even suspected that fossils 

 occurred in these exceedingly ancient beds. A few years ago, however, 

 evident traces of funoids and annelids were noticed in the upper strata of the 

 deposits, and quite recently the careful searchings of Dr. Holl have been 

 rewarded with well preserved shells in the lower beds, some 500 feet below 

 the fucoids and annelids of the superior strata. Dr. Grindrod's museum 

 exhibits excellent specimens of both divisions of this rock. The next section 

 of the collection comprises an unequalled series of the fossils of the Black 

 Shale — an equivalent of the Lower Lingula flags of "Wales. These have been 

 mainly collected by the unremitting efforts of Mr. H. Turner, of Pauntley. 

 They consist almost exclusively of minute crustaceans, chiefly trUobites, some 

 of which, at present unnamed and almost unknown to science, exhibit the 

 most extraordinary forms, literally bristling over with delicate spines. In this 

 zone there also occurs a minute lingula, and one or two other trackeopods. 



The Lower Silurian system as developed in the neighbourhood of Malvern 

 is remarkable for the entire absence of both tho great Llandeilo and the 

 Caradoc formations. This portion of the museum is, however, finely illustrated 

 by a series of Llandeilo trilobites, collected, we believe, by Mr. David Griffith, 

 of Builth, and by an equally illustrative set of Caradoc species from the 

 typical rocks of Shropshire. 



Fossils from the Llandovery or May Hill Sandstone are next displayed, 

 forming the connecting link or passage beds between the Lower and Upper 

 Silurians. 



It is, however, from the Upper Silurian rocks that the finest and most 

 abundant specimens in this Museum are collected. Of these, the series of 

 Trilobites is especially remarkable. Glancing over them here collected together 

 is a very real glimpse at the inhabitants of the Pateogoric seas. Amongst 

 others, we may particularly mention a group of that rare species Sphairexochus 

 vnirus, of which, until the forming of the Malvern Tunnel, only three speci- 

 mens were known. Equally fine, too, is a group of the delicate Encrinurus 

 punctatus—ao delicate that an individual with its projecting eyes, side spines, 

 and back spine was td lately quite unheard of. Here, however, are more than 

 a dozen in a state of absolute perfection ; some coiled up as if taking a nap, 

 others apparently walking towards an enemy with spines erect, breathing, as 

 it were, both defence and defiance. Tribolites of all sizes are gathered here 

 from the mud of the primordial oceans, from the minute Cypkaspis, with its 

 long spines, to the gigantic ffomalonotus, 6 or 7 inches in length. The most 

 jealous care in selecting only the finest specimens has resulted in magnificent 

 tablets of the choice CJwirurus, Lichas, and Phacopa longicaudatua, and its
