Griirley describes three species of Garyocaris which " from its resemblance to 

 Dawsonia may be a Graptolite " ; the species are G. Wrightti, G. oblongus, 

 and G. curvilatus. Dawsonia is represented by two new species : D. monodon 

 and D. tridens. A new genus — Phycograptus — is proposed and two species of 

 this genus are described : P. brachymera and P. laevis. Thamnograptus Barm nd ii 

 is also referred to, and it is suggested that the " thecse appear to have been 

 excavated out of the substance of the branch."

In addition, a new species is described, viz. Diplograpsus Ruedemanni, being 

 one of the forms mentioned by Ruedemann as D. pristiniformis in his paper on 

 the "Mode of Life of the Graptolites."
