178 Reviews — B. Smith's Physical Geography. 



a comparison between the lists of fossils then published and those in 

 the pamphlet just issued shows how much has since been accomplished. 

 For example, the number of Sponges recorded has been increased from 

 6 to 20, and of Echiuoderms from 39 to 52 ; while among Cephalopoda, 

 the species of Ammonites (still happily recorded under that generic 

 name) have been increased from 5 to 13 — the Ammonites Bravaisianus, 

 d'Orb., of the older list being now recorded as A. Neptuni, Gein., as 

 notified in Mr. Jukes-Browne's Cretaceous Rocks of Britain, vol. iii, 

 p. 469. 



A very great deal of additional information is now given with 

 regard to the Chalk zones, and especially to the sub-zones of the 

 Actinocamax quadratus zone, " which are capable of being separated 

 all through the county." The following are the palosontological 

 divisions adopted: — 



Belemnitella mucronata. Terebratulina ' gracilis '. 



Aotinocamax quadratics, sub-zones — Inoceramus labiatus and Mhynchonella 



Aotinocamax quadratus. Cuvieri. 



Offaster pilula. Actinocamax plenus. 



EcJiinocorysscutatus,N&x. d&pressus. Holaster subcjlobosus. 

 Marsupites testudinarius. Ammonites varians and Mhynchonella 



Micraster cor-anguimwi, with Uinta- Martini. 



crinus-ba,n& at top. Plocoscyphia labrosa and Stauronema 



M. cor-testudinarium. Garteri. 



Holaster planus. 



The authors have endeavoured to visit every chalk-pit in Hampshire, 

 and they have zonal records of about 180 sections. Mr. Brydone 

 hopes shortly to publish a zonal map of the county. In the full list 

 of fossils now printed references are given to the particular pits or 

 ether exposures where the zones have been identified. 



In Appendices the authors contribute definitions and figures of the 

 several forms of Bourgueticrinus found in the Hampshire Chalk, and 

 known under the specific names of B. ellipticus and B. cequalis. They 

 likewise describe and figure some varieties of Echinocorys scutatus. 

 The illustrative plates are excellent. Dr. F. L. Kitchin also describes 

 Thecidea Brydonei, a new species from the zone of Belemnitella mucronata. 

 This is figured in the text.

fllHIS work may be described as a concentrated essence of Physical 



Geography. Parts i and ii contain brief but concise accounts of 



the Solar System, the earth, its seasons, tides, and main features. 



of the atmosphere, climate, and geographical distribution of plants 



and animals on land and in water. The larger portion of the work. 



nearly four-fifths of it, is given up to the composition, structure, and 



erosion of the land, and the origin of the physical features : subjects 



appropriately dealt with by one who has gathered knowledge abroad, 



as well as in this country where he has been actively engaged for some 



years on the Geological Survey. 



As examples of the illustrations we may mention Turf-cutting in 

 Donegal: Anticline in Coal-measures, Saundersfoot, Pembrokeshire;
