of a needle-sTiaped liyoid bone comparable to tbat of living birds in 

 its entirely similar form. Those many very vt^eighty resemblances 

 which, the ArchcBopteryx shows to the form of skull in the Ptero- 

 sauria will come under discussion in the detailed description. In 

 conclusion, it may be mentioned that the excavation of the shoulder 

 girdle, which is not yet finished, on further investigation may prove 

 that the portion which Vogt considered to be the coracoid is really 

 matrix, so that so far as can be judged from its preservation, the 

 form of the shoulder girdle must be removed from things known. 

 And it has yet to be proved whether the form of this part of the 

 skeleton will support the relation of the ArcJiceopteryx to birds or 

 reptiles.

I. — Guide to the Exhibition Galleries of the Department 

 OF Geology and Paleontology, British Museubi (Natural 

 History), Cromwell Eoad, South Kensington. 8vo. 56 pages. 

 With a Plan, and 31 Woodcuts. Printed by Order of the 

 Trustees. (London, October, 1882. Price threepence.) 



THE Galleries containing the Mammalian and Keptilian remains 

 having been completely arranged, and most of those set aside 

 for the fossil Fishes, Molluscs, Crustaceans, etc., having received 

 their palEeontological treasures, though not yet in every case fully 

 developed, the Trustees of the British Museum have without delay 

 published their first illustrated Guide for the use of both scientist 

 and amateur, as well as for the general public, desirous of knowing 

 what these things are, — how they bear on the notions and thoughts 

 of to-day, — and how far Nature to-day resembles herself in the Past. 

 Much valuable and precise information is given in a condensed, 

 form in this " Guide," especially about the higher Vertebrates, with, 

 numerous good woodcuts. Several of these are original, and others 

 have been borrowed from first-class books. The classification of the 

 animals, vertebrate and invertebrate, and their distribution in time 

 and space, are points well kept in view ; and, except that the special 

 notice of the Corals, Sponges, and some other low or simple animals, 

 which have not yet been arranged in their cases, is postponed for the 

 present, both student and general observer will find this " Guide " a 

 useful little manual for practical, and to a great degree for philo- 

 sophical zoology recent and fossil (palteontology). J.

 Emeritus Professor of Geology and Mineralogy in University 

 College, London. New and Enlarged Edition. Large Sheet. 

 (Eeynolds and Son, Strand, London.) 



THE Chart, originating many years ago, has been revised and 

 improved from time to time, keeping up with the progress of 

 geological knowledge, and thus enabling the Student and the 

 Amateur to catch at a glance the main points and chief features of 

 his subject. In the present edition the proposed recognition of the
