and they occupy the same relative position with respect to 

 the " Kurow schists" that the Te Anau series does to the 

 Ivakanui series. 



In his " Outhnes of New Zealand Geology " Sir James 

 Hector recognised the close association of the Te Anau and 

 Kakanui series, and referred them to the Devonian period, as 

 under :• — '■'■'• 



" XIII. Devonian. 



" (a.) Te Anau series. 

 " (b.) Kakanui series." 



In the latest classification of the Geological Survey,! dated 

 the 30th June, 1887, the Kakanui series disappears from the 

 table of formations, and is apparently, but without explana- 

 tion, included in "XIII. Lower Devonian — -Eeefton beds," 

 which had no existence in the classification of the pi'evious 

 year ("Outlines of New Zealand Geology," p. 40). 



Briefly summarising the foregoing, we find that the highly 

 altered phyllites and quartzites of the lower flanks of the 

 Kurow Mountains are succeeded conformably by the less 

 altered Mount Mary fossiliferous slates and sandstones. The 

 former are included in the Kakanui series of Hector and 

 Button, and the latter in the Kaikoura formation of Hutton 

 and Te Anau series of Hector. 



I am inclined to agree with the early opinion of Hector 

 .and Hutton that the " Kurow schists," notwithstanding that 

 they pass insensibly into the Mount Mary series, are suffi- 

 ciently distinctive to be separated from the upper series. 



For the lower and more altered group of Kurow rocks I 

 propose to revive the old " Kakatiui series" of Hector, in 

 which they were originally included. For the upper and 

 less altered group I do not think there is a more appropriate 

 name than Mount Mary series. 



The Mount Mary series undoubtedly includes the Te Anau 

 series of the Geological Survey, of supposed Devonian age, 

 but there are several reasons why the name " Te Anau" 

 should be abandoned. In the first place, we have it on the 

 authority of Mr. McKay that the rocks typical of the Te 

 Anau series do not occur at Lake Te Anau ; and, further, the 

 Te Anau series has always been difficult to distinguish from 

 rocks supposed to belong to the Maitai series of the Geo- 

 logical Survey. 



On the other hand, the rocks at Mount Mary are fos- 

 siliferous, and perhaps this is the best reason for attaching 

 the name of that mountain to the new series. The proposed 

 subdivisions of this succession of rocks are as follows : —
