 f. 63. Glossy brown with spiral bands of brown spots ; 

 whorls five or six, the upper part set round with two 

 series of tubercles ; outer lip slightly toothed, pillar 

 lip rugged and granular. 1 to 2. Weymouth, Dunbar, 

 Plymouth Sound, rare. I have copied this description 

 from Fleming as I have never met with an authenti- 

 cated specimen in a British cabinet; he further adds 

 " in the specimen sent me, the whorls have numerous 

 fine waved spiral stria." It is certainly a young shell 

 and not improbably the adult is the common W, Indian 

 Testiculus.
