STEUTHIOLAEIA. 221 



finely spirally lineate ; aperture broad, channelled in front ; outer 

 margin much thickened, sulcated within, the sulci corresponding 

 with the elevated bands on the exterior of the body-whorl, callosity 

 continuous and spreading over part of the penultimate whorl ; 

 inner margin thickly callous and spreading. 



Dimensions. — Length 75 mm. ; breadth 42 mm. ; length of 

 aperture 36 mm. 



Form, and Loc. — Pliocene : MacLean's station, ISTapier, 'Sew 

 Zealand. 



G. 9545. An example of the adult. Sir James Hector Coll. 



Struthiolaria cincta, Hatton. 



1873. Struthiolaria cincta, Hutton, Cat. Tert. Moll. N.Z. p. 11. 



"Ovate turreted; spire acute; whorls six, keeled; body-whorl 

 hollowed in the middle ; spirally ribbed, ribs thin, narrower than 

 the intermediate grooves, smooth ; keel subnodular ; columella 

 somewhat callous, slightly bent ; outer lip not much thickened ; 

 axis 2'1 ; breadth 1'4." — Hutton. 



Several examples apparently referable to this species are found 

 in the Museum collection ; but they are not well preserved, and 

 none are sufficiently perfect to allow of dimensions being accurately 

 taken. The largest of them is about If inches in length. 

 I Form, and Loc. — Miocene : Akuakua, New Zealand. 



! G. 9542, G. 9617, G. 9623, G. 9624. Many specimens showing 



variation in the ' development of the slightly tuberculate carinas 

 of the body-whorl, many having mere traces of tuberculations, 



I others approaching S. tuber ciclata, Hutton. Sir James Sector Coll. 



Struthiolaria, sp. 



The following specimens from the Miocene of New Zealand, for 

 the most part fragments imbedded in shelly limestone, form part 

 of the Sir James Hector Coll. : — 



G. 9552. Whorls broadly tuberculate at the periphery ; from 

 Taipo, east coast of Wellington. 



G. 9600. Globose species, probably referable to Tijlospira, but 

 not well preserved ; from Waipara.
