Shell solid, oblong, coronated ; spire very little raised, apex 

 obtuse, whorls 6, with white nodes, the interspaces with yellowish 

 brown spots, spirally sulcated at the lower part with 7 rather 

 narrow grooves, the upper being the finest; colour cream yellow 

 with snow white flexuous streaks and blotches in the centre; 

 coluinellar base dark brown, ornamented with snow-flake spots; lip 

 straight, somewhat thickened, interior of the aperture white.

//rt6.— Shark's Bay, W.A. {Mr. Podesta). 



The unique specimen of this new cone is slightly sea-worn but 

 quite distinct from any of the species known to me. The upper 

 half of the shell is quite smooth, the lower part having 6 or 7 

 rather narrow spiral grooves, and the centre ornamented with 

 snow white flexuous streaks and blotches. 



I have seen a second specimen formerly for many years in the 

 collection of the late Mrs. Brazier, which diflers ver}' much, both 

 in colour and markings. I define it under a new varietal name. 

 CoNUS Kenyon^ var. Arrowsmithensis, var.nov. 



Spii-e more raised, apex pinkish, less obtuse; colour flesh tinge, 

 ornamented in the centre with somewhat broad white arrow-shaped 

 markings, with the points to the right, spirally sulcated with 4 

 rather narrow but deep grooves rather wide apart, with two 

 others below close together; columella tinged with violet, base 

 tipped with brown intermingled with snov/ white spots, interior 

 of aperture very light violet; lip thickish, straight. 



Long. 36; diam. maj. 21; aperture, 28 mm.
