2. Triton radialis, spec. nov. Plate v. fig., 8. 



Shell acutely ovate, with a high, sloping, distorted spire- 

 terminating in an acute apex, consisting o£ two polished 

 whorls, the anterior one slightly shouldered, or bicarinate, 

 the posterior whorl ends in a blunt, short, erect, lateral point. 

 "Whorls five, excluding the nuclear whorls, flat, angulated over 

 the anterior suture ; the carination broadly and deeply crenate- 

 dentate. The surface ornamented with spiral threads, increas- 

 ing from six on the posterior slope of the earliest whorl to 

 about 30 on that of the body whorl, but at the same time they 

 gradually diminish in strength, until they are barely visible- 

 to the unaided eye. Base of the body whorl similarly sculp- 

 tured, but with two strong lir?e, and three or four on the beak. 



Avarices at about four-fifths of a whorl, deeply and broadly 

 crenately-serrated at the carination. There are four or five 

 large intervariceal serratures on the posterior carination, and 

 three smaller ones on the anterior carina of the body whorl, 

 becoming obsolete at half the length between the varices. 

 Aperture ovate ; outer lip lirate within ; inner lip thin, erect, 

 lirate within , beak shorter than the aperture, abruptly bent to 

 ehe right, and reyerted. 



Length, 40 ; breadth, 28 ; length of aperture and canal, 24. 



Localitij. — " G-astropod-bed " of the Eiver Murray cliffs,. 

 near Morgan. 



This Murray fossil might at the first glance be taken for 

 T. Abbotti, but it has fewer and larger tubercles, which produce 

 a greater distortion of the spire, whilst the posterior slope is 

 much broader and very feebly lirate and not cancellate on the 

 last whorl, which is moreover not at all or but feebly biangu- 

 lated ; the shell is proportionately wider, the canal shorter, 

 and the apex is very different. 



3. Triton gibbus, spec. nov. Plate v., fig. 9. 



Shell biconical, with a short distorted spire of flat whorls, 

 imbricating and crenately-dentate at the suture. Last whorl 

 bisected by a very high, sharp, crenately-dentate keel, with a 

 precipitous anterior slope, and the base contracted into a 

 broad, twisted, and reverted beak. 



"W^horls five (excluding two smooth apical ones ending in a 

 laterally-elevated, obliquely-truncated point), with a varix at 

 about four-fifths of a whorl, much depressed or almost concave 

 for the anterior third of each intervariceal space. Intervari- 

 ceal crenulations five, confined to the posterior two-thirds of
