Dr. E. M. R. Shalcespear — Netv Zealand Graptolites. 147 



specimens which occur in the present collection it appears that they 

 belong to a primitive type of Diplograptus allied to Liplograptus 

 inutilis, Hall. It may be a new species. 



The fauna represented in the second band {h) seems not to have 

 been detected by Mr. Eell and his assistants, though its previous 

 recognition in J^ew Zealand is evident from the figures of graptolites 

 given by the late Sir James Hector (Handbook of New Zealand, 1886, 

 p. 82). In this band the most characteristic species ^re Bichjmograptus 

 nanus^ and Tetragraptus Bigshyi, while Bidyniog. gihheruliis appears to 

 be entirely absent. 



Below is a table showing the distribution of these New Zealand 

 graptolites in America and Great Britain ; and an examination of this 

 brings out clearly the great similarity between these two New 

 Zealand faunas or sub-faunas and those of corresponding age in the 

 Northern Hemisphere. 



cc = very commou ; c = common ; fc = fairly commou ; r = rare ; rr = very rare.
