laterally immersed ; wliorls below the apex seven, of very- 

 slow increase, convex, much contracted at both sutures, 

 stoutly but narrowly ribbed, lirate. Transverse plications- 

 about 11 to a whorl, narrow, very prominent, slightly nodulose, 

 almost obsolete on the body whorl. Spiral ridges angular, 

 four of which on the middle and front very prominent, with 

 an intermediate thread. Three slender lirse on the posterior 

 slope ; whole surface transversely closely wrinkled. Base- 

 gradually attenuated, ornamented with alternately large and 

 small angular encircling ridges. 



Length, 44 j breadth, 13 ; length of aperture, 12, of canal, 12.

This is a more slender shell with narrower cost?e than 

 F. dumetosus ; it differs from F. MerecUtlicd by its coarser orna- 

 ment, more convex whorls, and less ventricose body whorl. 



19. Fusus dumetosus, spee. nov. Plate ix., fig. 1. 



Shell stoutly fusiform, whorls rounded and spirally ridged ; 

 differing from F. ustulatus, Eeeve, by the whorls being of less- 

 rapid increase, last whorl not so ventricose, and by the absence 

 of axial plications on the anterior whorls, at least, on the body 

 whorl. 



Length, without apex, 31'5 ; breadth, 12-5 ; length of aper- 

 ture and canal, 18. 



Locality. — Upper beds at Muddy Creek {J. Lennant .') 



20. Fusus Tateanus, T. Woods. Plate xiii., fig. 5. 



F. Tateana, Tenison "Woods, Proc. Roy. Soc, Tasmania, for 

 1876, p. 94. 



Shell ovately fusiform ; whorls seven (without apex), the 

 body and penultimate whorls roundly convex, obscurely dis- 

 tantly spirally lirate and transversely striated ; the rest of 

 the spire whorls flatly convex, the posterior ones costated and 

 lirated. There are about ten costsD in a whorl, and about 15 

 subangular threads equi-distant and about equal to the inter- 

 vening sulci. Last whorl rather sloping to the suture ; aper- 

 ture elliptic, outer lip thin and abruptly incurved to the long, 

 narrow canal. 



Leni>th of an incomplete specimen, 86 ; breadth, 35 ; length 

 of aperture, 30; o£ canal, so much as known, 25.

This fossil is very distinct from any living species, but is 

 remotely related to F. longcevus of the European Eocene.
