T. Sagrfe simili, sed magis depressa, anfractu ultimo minoii, 

 niagis rotundato. 



Smaller and more globose than the last, with the last whorl 

 smaller in proportion and less angulated, probably however only a 

 variety of H. Sagra. Cuba.

T. H. Sagrae simili, sed magis globosa,striis concentricis regula- 

 ribus, distinctis. 



Rather lighter and much more globose than the last, with the 

 stiise distinct and regular. 



12. H. FESTivA. (pi. i. f. 9.) Gray. Beech. App. 



T. H. Sagrae simili, sed concentrice lirata, interstitiis rubro- 

 liiieatis. 



Shaped like Helicina Sagra, but concentrically grooved, with the 

 interstices coloured red. The figure is taken from Beechey's 

 Appendix; we are inclined to think it over-coloured. 



Sec. 3. Shell more globose, thinner, notch deeper,
