The above is a condensed translation of the author's Latin des- 

 cription. I have never seen this species, and am inclined to agree 

 with Mr. Sowerby, that it is possible it may belong to the genus 

 Heuiifiisus rather than Latirus. At all events it is a form that 

 deserves more study. 



19. Latirus (Peristernia) sowerbyi Melvill. 



Latirus {Peri sternia) sowerbyi^. C. Melvill, Proc. Malac. Soc, Lond., 



vol. vii., p. 217, fig. 



The following is taken from the original Latin description : — Shell 

 moderate in size, fusiform, attenuate both apically and basally, solid, 

 whorls seven, actual apex small, smooth, the remaining whorls slightly 

 impressed at the sutures, th5 upper becoming rapidly attenuate, the 

 body whorl much exceeds all the others, attenuated at the base, pro- 

 longed, adorned with thickened ribs, of a brown-black or chestnut 

 colour, spirally thickly lirate, the hr?e irregularly white-pustuled, 

 especially towards the base, the aperture is white or violet, pyriform, 

 canal produced, columella shining, and obscurely thrice plaited. 



Long.: 19; diani.- 8 mm. 



Hab. : Galapagos Isles (?). 



I have seen four examples of this pyriform little species. The 

 locality though probably correct, is not absolutely certain. Mr. 

 Sowerby kindly presented me with a co-type, the actual type having 

 been placed by him in the British Museum.
