The body whorl of this fine species, vvhich I have named after tbat 

 distinguished conchologist Dr. Beck, is upvvards of G inches in 

 length. 



I have long had a bleached specimen in my collection, but the 

 description above given is taken from one with niore colour and 

 in better condition, thoiigh not good, in the cabinet of Miss Saul. 

 My specimen is somevvhat shoiter. There is a very large indivi- 

 dual lately added to the British Museum.

This is an elegant shell, approaching a little in some of its cha- 

 racteis to Fol. Lyriformis, but differing vvidely from it in others. Of 

 the totai length of Fol. concinna two inches and ahalf are occupied 

 by the body whorl, and it is only in the transversely striated plica- 

 tions of the spire, vvhich are hovvever more distant than those of 

 the spire of Fol. Lyriformis, that the resemblance occurs, for the spire 

 of Fol. concinna is very short in proportion to its body \vliorl, \vhile 

 the opposite character is strongly developed in Fol. Lyriformis. In 

 this respect it comes nearer to Fol. gracilis, as well as in the foim
