As the attention of geologists has lately been re-directed to the above subjects by Mr. S. V. Wood and Prof. Harkness, I venture to hope that the following notes and observations, made during visits to Wasdale Crag and the neighbourhood, on the 7th and 15th of last June, will not prove uninteresting to the readers of the Geological Magazine.

The name Dicranograptus was proposed by Hall, in his Memoir on the “Graptolites of the Quebec Group” (p. 112), for certain forms of Graptolites, some of which were then included in the genus Didymograpsus, and others in Diplograpsus. He, however, only considered these forms as constituting a sub-generic group of his genus Climacograptus, believing them to have a similar structure.

For many years past I have, at intervals, devoted attention to Tertiary Brachiopoda, and I now propose to note down some remarks in connection with those of Italy.
