408 Reviews — Angelinas Silurian Crinoidea. 



rolled and water-worn bones, many of them belonging to Cetaceans 

 that could not have lived in the shallow seas of the period : these 

 remains have been derived mostly, if not entirely, from the Middle 

 Sands, where they abound in the unrolled and connected state. 



Littoral beds occur East of Antwerp, indicating a later advance 

 of the sea, possibly that produced by the depression which iu 

 Suffolk introduced the Chillesford series. 



The geography of the Upper Sands period resembled in the main 

 that of the preceding epoch, with the addition of a wide sheet of fresh 

 or brackish water, which stretched from Austria to Tartary, and left 

 as its isolated relics the Black, Caspian, and Aral seas. 



[Copious lists of fossils, with statistical analyses of each, are 

 adduced by the author in proof of his views, but for these the reader 

 is referred to the original. The author desires the writer of this

 to any one interested in the subject. Applications may be made to

I. ICONOGRAPHIA CrINOIDEOKUM IN StRATIS SuECI^ SiLTJRICIS 



FossiLiTJM AucTOEE N. P. Angelin. Opus Postumum Edendum

THEEE is probably no better proof of disinterested regard which 

 can be displayed for a deceased scientific man, than that his 

 friends should undertake the very difficult and laborious task of 

 preparing his posthumous works for publication. It was this feeling 

 which led the disciples of the illustrious Cuvier to publish "Le 

 Eegne Animal," and Charles Murchison to edit "Falconer's Palseon- 

 tological Memoirs." A noble example of this self-denying spirit 

 is shown in the work before us by Prof. S. Loven, and Dr. G. 

 Lindstrom, the former a colleague of Angelin's, and the latter his 

 recently appointed successor at Stockholm. 



The unpublished MSS. of Angelin, handed over to the Academy 

 by his family, were found to consist of various memoirs on the 

 Trilobites, Cephalopoda, Graptolites, etc., but for the most part in- 

 complete and unarranged. 



In 1851 he published under the title of " Palseontologia Suecica " 

 the first part of his Monograph of the Silurian Crustacea of Scandi- 

 navia ; the second part entitled " Palseontologia Scandinavica " 

 appeared in 1854. At his death in February, 1876, all the beautiful 

 plates, 29 in number, published in the present volume, were found 

 ready prepared and lithographed, part of the text was printed and 

 part was found in MS. The Editors modestly lay claim only to 

 the plan and systematic arrangement of the work (except the 

 Cystidea), they having given Angelin's own generic and specific 

 characters, merely reducing the same to order, and adding some 

 needful notes on the synonymy. The name of Prof. S. Loven,
