served in the Upper Cretaceous beds of Southern Erance aud the 

 HcmijnieusteshcH?, oi'ij'dlMchhtkn. This seems to point to similar 

 physical conditions under which the Upper Cretaceous beds were 

 deposited in South-western France and Baluchistan. Another most 

 remarkable fact is that the Hemipneustes beds do not share a single 

 specimen with the Upper Cretaceous beds of Palestine aud North 

 Africa. It may be doubtful whether strata of the age of the Hemi- 

 pneustes beds are developed in Palestine ; but they certainly occur in 

 North Africa. 



" These considerations Itad us to the conclusion that the Hemi- 

 2)neustes beds are oi Upper +Senoniau age, and most probably represent 

 the etage Maijstrichtien. The fauna therein contained bears hardly 

 any resemblance to the fauna of similar age in Southern India or 

 Northern Africa. On the other hand, it exhibits the closest relation- 

 ship to the fauna contained in beds of similar age of South-western 

 Prance. The fauna of the Hemipnei-tstes beds must therefore be 

 considered as belonging to the European province of the later 

 Cretaceous sea, and living probably in close proximity to its eastern 

 shores. This sea was most probably divided by a comparatively 

 narrow land-barrier from the sea in which the Upper Cretaceous 

 fauna of Southern India lived— a view first expressed by Dr. Blan- 

 ford, and not, as 1 erroneously stated, by the late Professor 

 Neumayr." 



The 28 quarto plates supply good illustrations of seventy-nine 

 Upper Cretaceous Baluchistan species, fully described as 3 Rhizopods, 

 3 Corals, 16 Echinoderms, 26 Pelecypods, 24 Gasteropods, 6 Cepha- 

 lopods, and 1 Crustacean. The several generic facies remind us of 

 some of the Lower Cretaceous, as well as of many of the Upper 

 Cretaceous, forms of Western Europe. 



The author is conscientiously careful in terminology and nomen- 

 clature, and is very correct in orthography; yet the modem 

 confusion in the names of the Ammonoidea has entangled him, as 

 usual with less educated writers, and allowed him to let slip a false 

 concord in the specific name of Indocems at several pages.

After dwelling on the insufficiency of the common method of 

 describing the hinge-teeth of the Blvalved Molluscs {Bivahia, 

 Linnc, Acephala, Cuvier, LamelJibrancJiia, Blainville, PeJecijpoda, 

 Goldfuss), which are here treated under the group-name given by 

 Goldfuss, the author proceeds to illustrate and explain the weU-based 

 and philosophical system of terminology for these teeth as elaborated 

 by Munier-Chalmas, Stefanescu, and Bernard, and founded on the 

 development of the hinge. Although the homologies are as yet
