BRITISH GRAPTOLITES. 



Graptolites are wanting. Twenty-six forms of Graptolites are described, and well 

 illustrated by figures drawn by the author. Of these forms twelve are given as 

 new — Azygography Mobergi, Glossograptus Scanieus, Cryptograptus lanceolatus, 

 Thysanograptus spinatus, Diplograptus Tornquisti, D. notabilis, D. propinquus, 

 Dicranograptus irregularis, Dicellograptus vagus, D. minimus, Nemagraptus 

 subtilis, and Desmograptus Tullbergi. Founding upon specimens of which parts 

 are preserved in relief, the author discusses the probable form and structure of the 

 polypary and thecae in the genus Glossograptus. 



A description of the geology of a wide region of Northern 

 Burma, surveyed by the author ; with notes on the 

 characteristic fossils and a correlation of the containing 

 formations with their Asiatic, European, and American 

 equivalents. 



In this work there is made known for the first time the 



discovery of Graptolites in the Lower Palaeozoic rocks of 



A list of the forms collected by the author and Mr. J. 



Coggin Brown, and identified by Miss G. Elles, is given. All the forms 



named are referred to well-known British species. (See also Coggin Brown, 



' Records of Geological Survey of India.')

Notable from the point of view of British Graptolitic 

 literature as recording the earliest discovery of Graptolites 

 (Clonograptus) of Tremadoc Age in deep borings in Central 



England. 



In this paper Tornquist gives an historical and critical 

 summary and review of the discoveries and opinions re- 

 specting the distribution of those species of Graptolites which 

 are of zonal significance in the various recognised formations 

 and sub-formations of the Lower Palaeozoic strata of Sweden, 

 Norway, Denmark and Bohemia, and Britain. References to 

 the papers cited are given in footnotes, and the most recent 

 zonal nomenclatures for the Swedish Graptolite-bearing strata are given at appro- 

 priate places in the text. 



This Tenth Part of the British Monograph is composed 

 of three divisions. The first division deals with those forms 

 of the Monograptidse which the authors arrange in their 

 seventh group Rastrites (auctorum). Of these only one species 

 is noted as new, Monograptus (Rastrites) setiger. 



The second division is devoted to the genus Cyrtograptus 

 (Carruthers).
