brown color, but young specimens are more livid, and faintly 

 banded with chestnut.

P. shell acuminately ovate, greenish white, spire produced 

 acumiuatf,inamilIato; whorls 6, angulate and bicarinate above, 

 with tranverse rounded lirce (equalling the interstices in 

 width), and cancellated with scaly imbricate lamelloe ; aperture 

 acutely ovate, stained deep blackish purple within ; inner 

 lip somewhat flattened and partly enamelled, blackish purple ; 

 outer lip slightly crenulate. Long Bay, Southport, common. 



This shell approaches in habit the P. Flindersi of Adams, 

 and Angas, but it is much smaller and more like a Littorina, 

 while the other resembles a Trophon. Its deep violet black 

 mouth is very characteristic. P. Flindersi has a violet mouth, 

 but very much paler and clouded. 



Trophon umbilicatus, n.s. T. t. ovata, lutea velpaUide castanea, 

 soJida ; spira elata, anfrac 5-6, superne ancjulatis et concavis, con-

 plicas squamato-imbricatis ; sqiiamis post columellam validis, elevatis,

 intus dentato ; labio columellari expanso ; umbiUco squamis imbricatis, 

 rotumlatis marginato. Long. 27. Lat. 15. 



T. shell ovate, yellow or pale chestnut, solid, spire raised ; 

 whorls 5-6, angulate above and concave, conspicuously plicate 

 lengthwise (8 in the last), and transversely thickly lirate, liras 

 alternating large and small, the larger flattened, squamately 

 imbricated over the plaits ; squamae behind the columella valid, 

 raised and canaliculate ; at the sutures, the plaits and lirae 

 obsolete ; outer lip crenulate outside and toothed within ; 

 columella lip expanded, umbilicus margined with rounded im- 

 bricated scales. 



Eather uncommon. East Coast. At one time I considered 

 this a Tasmanian variety of T. Sanlei/i, Ang. but a com- 

 parison of many specimens shows mo that the present is an 

 entirely different shell, very much more scabrous. The um- 

 bilicus and its margin are also peculiar and distinct.
