fine, raised lines. There are about 20 lirjc on the posterior 

 slope of the last whorl, of which one median and one or two 

 near the suture are stouter than the rest, and irregularly 

 granulose ; the anterior part is similarly ornamented. 



Aperture quadrately oval ; outer lip tuberculate within : 

 inner lip erect, with a tubercle at the poiut of the pillar, to 

 which is opposed a stout tubercle on the outer lip ; canal long, 

 much recurved. 



Length, 37 ; breadth, 17 ; length of aperture 9, of canal 12. 



Locality. — Lower beds at Muddy Creek. 



T. Woodsii was founded on an immature example, which does 

 not so characteristically represent the species as the adult 

 specimen which is here figured. 



Var. — The specimens from the Eiver Murray Cliffs and 

 Schnapper Point are much larger, and the lirae usually more 

 granulated. Length 50, breadth 26, length of aperture 18. 



6. Triton textilis, spec. nov. Plate v., fig, 12. 



Elongate-fusiform, with a much produced conical spire ; apex 

 acute of three rounded lirate whorls, ending in an acute 

 upward-curved point. 



Whorls six, excluding the embryonic ones, with a high ante- 

 median serrate-dentate carination ; but much depressed behind 

 each varix, and with the sudden enlargement in front of it 

 there is produced considerable distortion of the spire. Last 

 whorl medially angulated, with an alniost precipitous slope 

 anteriorly. 



Surface ornamented with numerous (about 30 on the pos- 

 terior slope of last whorl) flat, equal, spiral threads, with a 

 little wider interspaces, cancellated by close, fine, raised lines. 



Varices rather broad, concave axially, rather acute, without 

 tubercles, and ornamented as the rest of the surface, situated 

 at about four-fifths of a who id. The inter var iceal nodulations 

 vary from six to eight, decreasing in size anteriorly. 



Aperture oval ; outer lip with a sharp, minutely-wrinkled 

 margin, with an inconspicuous dentate, with ridge within, 

 abruptly terminating at the canal ; inner lip erect, with a few 

 corrugations anteriorly, and a small tubercle at the point of 

 the pillar. Canal long, much recurved. 



Length, 37 ; breadth, 20 ; length of aperture and canal, 22. 



Localities. — Blue clays at Schnapper Point ; and lower beds 

 at Muddy Creek. 



This species very much resembles T. Woodsii, but is more 

 distorted, the whorls more angularly elevated, by the absence 

 of an anterior carination on the body whorl, and by the more 

 numerous spiral lir^.
