104. 



19. Murex sublaevis, spec. nov. Plate iii., fig. 3. 



Shell eloDgate-fusiform, with a high scalar spire ; whorls 

 seven and a half, convexly angular, equally sloping from the 

 medial angulation to the sutures. Otherwise resembling 

 31. Eyrei, but also differing by the stouter varices, the absence 

 of lirse on the posterior slope of the whorls, fewer lirae on the 

 anterior part of the body whorl, which is attenuated less 

 abruptly into the beak. Inner lip faintly tuberculated within. 



Length, 25 ; breadth, 12 ; length of aperture and canal, 14i"5. 



Localities. — Adelaide bore ; and " Turritella clays," Blanche 

 Point, Aldinga Bay. 



20. Murex Legrandi, Johnston. Plate xi., fig. 8. 



M. Legrandi, E. M. Johnston ; Proc. -Roy. Soc, Tasmania, 

 for 1879, p. 32. 



Shell fusiformly turriculate, whorls six (apex wanting), those 

 of the spire bicarinate. Last whorl moderately convex, some- 

 what angulated in the posterior one-third, anterior to whicb 

 are nine angulated spiral carinae ; the transverse ornament 

 consists of thick distant threads forming slight granulations 

 at points of intersection with the lirae. There are five varices 

 on the last whorl, nine on the next, and increasing in number 

 posteriorly ; they are squamose, rather broad, irregularly dis- 

 posed, and produced into short, vaulted, spiny scales on the 

 posterior carination. 



Aperture oval, peristome entire ; outer lip with six stout 

 denticulations within, situated anterior to the angulation at 

 tbe carination. Canal much shorter than the aperture, open, 

 sinistrally curved. 



Length, 18 ; breadth, 8 ; length of aperture and canal, 9"5. 



Locality. — Table Cape, Tasmania (B. M. Johnston'.). 



Has considerable resemblance to M. cristatus, Brocchi, but 

 has fewer varices and lirae.
