l^^ Locality. — Everett's limestone quarry, Kakanui, New Zealand. 



Horizon. — Oamaruian (probably Miocene). 



Material. — Holotype and four paratypes ; one of the latter consists 

 of a dorsal valve only. 



Remarks. — The Kakanui limestone consists largely of hollow or 

 partially rilled shells of Brachiopods, a peculiarity of fossilization 

 being that the pores of the shells are obscured, so that in many 

 undoubtedly punctate shells, such as Terebratula oamarutica, Boehm, 

 the punctation cannot be distinguished even under a microscope. 

 The specimens of Thecidellina hedleyi are of a dull white colour and 

 show no sign of punctation, but it does not necessarily follow that 

 it is absent. No trace of deltidium can be seen, and this is in 

 agreement with T. maxilla, Hedley. In external form T. hedleyi 

 has more resemblance to T. Barretti than to T. maxilla, but is more 

 nearly trigonal than either of these species.
