A few remarks naturally arise from an examination of the species. 

 Commencing with the oldest or Jurassic, these bear the greatest re- 

 semblance in specific identity to those of our own country ; the 

 characteristic examples of Terebratula numismalis from the lowest 

 fossiliferous beds serving to point out the shales of the Woronzoff 

 road to be equivalent with those of our Lower Lias, as the presence 

 of Rhynchonella acuta, Gryphcca incurva, Ammonites Jurensis, and 

 A. jimbriatus from the village of Biasali, indicates the Marlstone or 

 Middle division of the Lias. 



The fossils received from Balaclava (principally Brachiopoda) 

 appear to be related to forms from the Lower or Inferior Oolite, 

 although for the most part specifically distinct from any met with 

 in England ; Rhynchonella senticosa, an Inferior Oolite species, being 

 the only one I have been enabled to identify from that locality. 



Fossils from the intermediate formations of the Secondary age are 

 absent in this collection, although several species, principally Cepha- 

 lopoda, are catalogued as belonging to the Oxfordian division from 

 Baktchserai by M. Du Bois de Montpereux, and from Kobselon the 

 south coast of the Crimea by M. D'Orbigny. 



In this collection are contained several species, principally Zoo- 

 phyta, from Soudaxioxia, forming part of a series formerly presented 

 to the Museum of Practical Geology by the Imperial School of Mines 

 at St. Petersburg, These fossil corals are perfectly undistinguish- 

 able from similar species met with in the Coral Rag of Steeple 

 Ash ton. 



The Neocomian or Lower Greensand group, as well as the upper 

 division of the Cretaceous series, has some few fossils identical with 

 British species. The principal part of the fossils from this forma- 

 tion are from Baktchserai, and are catalogued by M. Du Bois in 

 his ' Tableau de Fossiles de la Craie en Crimee/ 



An interesting form of spiral bivalve belonging to the Chamidce, 

 allied to our Requienia (Diceras) Lonsdalii, but more nearly to 

 Requienia Ammonia, Matheron, occurred in great abundance, ac- 

 companied by a large Nerincea allied to N. gigantea. Many frag- 

 ments of these species were collected by Major Hudson, 39th Regi- 

 ment, from a very coarse crystalline limestone used in the construc- 

 tion of roads between Balaclava and the Plateau. 



The Upper Chalk of Inkerman has supplied several species (prin- 

 cipally Ostrea) common to our own country ; the most important 

 and beautiful fossil, as well as the most abundant, from this locality 

 is the Crania spinulosa, Nilsson, before alluded to. 



The Nummulitic or Older Tertiary fossils are also principally ca- 

 talogued by M. Du Bois in his ' Tableau,' as occurring at Baktch- 

 serai. This collection contains some large and characteristic species
