topora elongata, V., are got incrusting Crinoids here 

 and in the shale. 



Ostracoda, 28 species. The very small Ostracoda 

 were scarce in this gathering. The rare Beyrichia 

 Klcedeni var. granulata, the scarce B. Kloedeni sub- 

 var. clausa, Strepula concentnca, iS. irregularis, Primi- 

 tia Rcemeriana, P. variolata, P. umbilicata, the very 

 rare Thlipsura angulata, the scarce Macrocypris Vinei, 

 M. elegans, Pontocypris Smithii, Bythocypris botellotdes, 

 B. testacella, and Cythere Vinei, were obtained from 

 this gathering. 



11. Wyke, Tickwood, near Much Wenlock.— The 



limestone here contained a large quantity of crys- 

 talline calcite ; and the man in charge of the kiln 

 maintained that the calcite would not make lime, and 

 threw it aside. This opinion is prevalent amongst 

 the quarry men of Scotland, who call crystals of any 

 description "congealt water." The idea is possibly a 

 very old one, the word crystal itself being evidently 

 derived from the Greek word ki^ystallon, ice. In the 

 yellow shale were a few well-rounded quartz-grains, 

 some small Brachiopoda, Polyzoa, numerous Crinoid 

 remains, some small quartz crystals, 14 specimens 

 of Lagena la^vis, some Spirorbis, one pearl, some 

 spicules of Astrceospongia patina, Roem., and some 

 of Hyalostelia gracilis, Hinde. 



Ostracoda, 15 species. These, with the exception of 

 Cythere Vinei, were all of the common sorts. 



12. Gleedon Hill, near Much Wenlock.— The fine 

 yellowish shale from over the Wenlock Limestone 

 contained a few well-rounded quartz-grains, some 

 minvxte masses of crystalline calcite, numerous Cri- 

 noid remains, Spirorbis, one Lagena, one pearl, one 

 minute coprolite, and some opaque and transparent 

 calcite. The Polyzoa from this gathering were of a 

 purple colour; could this be from fluate of lime? 

 I have never heard of fluate of lime entering into 

 the composition of fossils. 



Ostracoda, 11 species. The rare Bythocypris pus-
