in groups which are respectively confined to different geological 

 horizons. Amblypterus Kablikce is first discussed, and this seems to 

 be confined to the highest stratum of limestone in the Bohemian 

 Permian. A new species, A. verrucosus, is then described as the 

 earliest known Bohemian Paleeoniscid, This is closely related to 

 A. Duvernoiji, which next receives a brief notice. Dr. Fritsch doubts 

 the advisability of assigning to the latter form as many so-called 

 species as some previous authors, and points out the comprehensive 

 character of the diagnosis of A. Duvernoyi in the British Museum 

 Catalogue. He concludes the present "Heft" with an account of 

 the form commonly known as A. Vratislaviensis, and begins a similar 

 description of A. Bohani. 



A glance over Dr. Fritsch's drawings will well repay the ichthy- 

 ologist and anatomist ; and the careful manner in which the different 

 fossils are compared renders the work of equally deep interest to 

 the geologist. We can only conclude by congratulating the Director 

 of the Eoyal Bohemian Museum on the fact, that even the absorbing 

 duty of arranging his new cases and exhibition galleries does not 

 interfere with the progress of his great contribution to Palaeozoic 

 Palgeontology. -A- S. W.

1. " The Pleistocene Beds of the Maltese Islands." By John H. 

 Cooke, Esq., F.L.S., F.G.S. 



For the right understanding of the Pleistocene beds, a previous 

 knowledge of the physiography of the islands and of the earlier 

 sediments is necessary. A full description of the physiography 

 and of the character of the sediments, so far as they are necessary 

 for the understanding of the accumulations forming the subject of 

 the paper, occupies its earlier portion. Especially noticeable is the 

 absence of ordinary anticlinal and synclinal folding, and the pre- 

 dominance of monoclinal faults, which largely affect the character 

 of the surface. These faults were formed prior to the deposition 

 of the Pleistocene beds. 



The plateaux of Malta, rising to a height of 600—800 feet above 

 sea-level, occur south of the great east-and-west fault, which has a 

 downthrow to the north. They have no Pleistocene deposits upon 

 their summits. 



Three classes of superficial deposits are described : — 

 (a) Valley-deposits, including (1) those found on the higher slopes 

 of plains and plateaux, due to subaerial waste and rain-action, con- 

 taining land-shells and mammalian bones; and (2) those situated 

 at the bottoms of valleys, consisting of stratified layers of water- 

 worn sand, gravel, and large pebbles, occurring in such order as to 

 show that the agents which produced them have greatly decreased 

 in intensity.
