6. 



Caten'ata. V. with an oblong-oval, ftrong, fub-pellucid, white. 



Tab. 6. f. 2. and extremely glofTy flicll, with four bands of ojjaque, 

 white, oblong fpots, connecied by linall rufous |"pots or 

 flreaks, in a very elegant manner, like fo many fmall chains : 

 upper volution fcarcely defined ; apex indented, involu- 

 ted : aperture the whole length of the fliell, linear: outer 

 lip thick, but not marginated, and obfoletely denticula- 

 ted : Columella quadriplicated, with two flrong, and two 

 faint folds. Length a quarter of an inch ; breadth at the 

 top one eighth. We obferved feveral of this new and 

 elegant fpecies in Mr. Swainson's cabinet of Britijk 

 fliells, under the title of Cyprcea catenata; who obligingly 

 favoured us with a fpecimen. 



The trivial name we have therefore continued it by, but 

 have been induced to place it in this genus, from the 

 flruclure of the Columella, and not being denticulated on 

 the inner lip. It is, however, a connefting link between 

 the two genera. We are wholly indebted to that Gen- 

 tleman for all we have been able to colleft concerning 

 this fhell : who, in a letter upon the fubjeft, fays, 



" I never found this (hell alive ; I got three or four dead 

 fpecimens, in the fediment at the bottom of pools of water, 

 (if thev may be fo called) left in the holes of the rocks in 

 St. Aujlle bay, near Fozoey : have heard of its being taken 

 off the Lizard, and alfo at Penzance." 



Is faid to be found in Guenifey of a fuperior fize.
