Of these fossils, Cirsotrema broivni and Pseudamussium 

 huttoni range from the Oamaru Stone to the base of the 

 Waihao greensands. Meoma crawfordi, which first appears in 

 the Mount Brown horizon, becomes a common form in the 

 Oamaru Stone. Kekenodon onomata is characteristic of the 

 Mount Brown beds, but at Ngapara and Marawhenua rises 

 into the Oamaru Stone. Pecten hutchinsoni, P. hochstetteri, 

 P. fischeri, and Plagiostoma laevigata appear to be confined to 

 the middle or Kakanui horizon. Amussium zitteli is found in 

 the Lower Waihao beds, but is never abundant. Aturia aus- 

 tralis, which is fairly common in the lower division, appears 

 occasionally in the Mount Brown horizon, but so far as known 

 does not reach into the Waitaki Stone. Of the two fine 

 examples of this nautiloid in the Otago Museum, one is from 

 the Lower Kakanui limestone, and the other from the Whare- 

 kuri greensands. Turritella kanieriensis is abundant in the beds 

 overlying the coal, while T. cavershamensis occasionally reaches 

 into the middle of the Mount Brown beds. Dentalium man- 

 telli, D. giganteum, Limopsis insolita, and Cucullcea alta are 

 distinctive of both the Waihao and Mount Brown beds.
