HISTORY OF RESEARCH. 



cli 



assigned to the family of the Dichograptidae, with the exception of those belonging 

 to the genus Didymograptus (already described in Part I). Twelve British 

 genera are recognised (including Phyllograptus, previously regarded by many 

 authorities as constituting a distinct family, and Azygograptus, hitherto assigned 

 to the Leptograptidse). Four new species are described and figured: Tetragraptus 

 reclinatus, 7'. Postlethwaitii, T. Amii (Lapw. MS.), Holographs Deani (Lapw. 

 MS.), and Bryograptus divergens.

A registration of the progress and results of the author's 

 researches and discoveries among the Graptolite-bearing 

 Lower Palaeozoic Strata of the State of New York. (See

 in New York," " New York State Palasontol. Ann. Rept.,"

An account of the discovery of two forms of Goniograptns 

 (Goniograptus Tliureani, M'Coy, and Goniograptus sp.) in 

 the Deep Kill Graptolite Beds of New York, with a dis- 

 cussion of the bearing of the structural details and successive 

 ontogenetic stages in Goniograptus upon the phylogeny of the 

 Graptolites in general. 



Identification of genera and species of Graptolites 

 collected from the Lower Palaeozoic Strata of New Bruns- 

 wick, with notes of correlation of the containing beds. 



A revision of the Graptolite species from Eastern 

 Victoria. A list of all the forms recognised up to date is 

 included with localities. Two new species, Did ymogr aphis 

 ovatus and Glossograjdtts Hermani, are described and 

 figured.
