13. Murex amblyceras, spec. nov. Plate ii., fig. 12. 



Shell elongate fusiform, with a high gradated spire, terminat- 

 ing in a small blunt mamiliate apex consisting of two smooth 

 globose whorls of which the tip is slightly turned down on one 

 side and immersed. Whorls seven, excepting the apical ones, 

 angulated, spirally lirate and transversely closely striated. 

 Varices simple, obliquely continuous from whorl to whorl, each 

 bearing a hollow, vaulted, reverted, blunt spine at the keel. 

 Last whorl a little tumid, with a rounded base, much contracted 

 and produced ; ornamented with about eight unequal lirae on 

 the upper part and about 20 similar ones in front of the keel, 

 the stouter ones ending in small digitations on the last varix. 



Aperture oval, with an elevated, thin, and continous peris- 

 tome ; margin of outer lip wrinkled ; canal long, curved, 

 aiearly closed. 



Length, 25 ; breadth, 10 ; length of aperture and canal, 16. 



Localities. — Lower beds at Muddy Creek ; blue clays at 

 Schnapper Point, Victoria. 



Has considerable resemblance to M. lasicinctus, but has no 

 intervariceal co stations or basal rib. 



14. Murex Hamiltonensis, spec. nov. Plate iii, fig. 6. 



Shell fusiform, somewhat thin, with a high spine of gradate 

 whorls terminating in a blunt, rather large apex (1"5 mills, in 

 diameter), consisting of two globose, faintly spirally striated 

 whorls, the extremity of which is immersed. "Whorls six, 

 those of the spire, excepting the nuclear ones, ventricose, sub- 

 quadrate, excavated at the suture, ornamented with four prin- 

 cipal rounded, slightly elevated, spiral threads (one of which 

 occupies the flat posterior area) and by rather distant fim- 

 briated laminae of growth and transverse striae. 



Last whorl somewhat tumid, narrowly flattened in front of 

 ihe suture, and rather abruptly attenuated into the beak ; 

 ornamented with spiral lirae and three varices. The spiral 

 lirae, of which two are on the posterior area and about ten on 

 ihe rest of the whorl, are equidistant, sometimes with a slender 

 interstitial thread, and raised into small arched scales as the 

 transverse laminae pass over them. 



Varices of thin adpressed foliations, three to each whorl, very 

 irregularly disposed and not continuous from whorl to whorl. 



xlperture oval-quadrate ; peristome continuous, thin, and 

 slightly reflected on the columella ; outer lip lirate within. 

 Canal shorter than the aperture, moderately arched to the left, 

 iind reverted. 



Length, 20 ; breadth, 9 ; length of aperture and canal, 11. 



Locality. — Lower beds at Muddy Creek. 



This Murex very closely resembles young examples of Bapana 

 aculeata.
