'^ Fissurella granifera, Pse., is a good species of Ghjplds.'' 

 I "will take opportunity of examining the animal of the above 



species, and report. I have frequently found it alive on the 



Sandwich Islands. 



Mimula fenestrata not in my collection. 



" Conus fusiformis, Pse., is a small species of Conclla." 



I have collected live and perfect specimens of the above. The 

 whole surface is granulose, resembling much larger species of 

 Cones, inhabiting Polynesia, which belong to genus Jlermes, 

 Mont. Conclla is a connecting link between the Conoid and 

 Columbelloid families. It is of little consequence with which it 

 is associated. 



" Cithara costellifera, Pse. MSS., = atomella, Sby., var." 

 The above name I have changed to ornata. I have collected 



perfect specimens of this species. It is quite distinct from the 



West Indian form. 



'^Borsoma corrugata,'Pse. MSS., = Clathurella nehulosa, Pse." 

 An error, probably, in labels. I have found but one speci- 

 men of the corrugata, which is a peculiar shell, in several 

 respects, and has never been out of my collection. 



" Natica undulata, Pse. MSS. Young of 3Iarroccana, Chem." 

 Mature and perfect specimens of the above have been lately 

 found. I agree with Mr. Cuming that it is distinct from the 

 West Coast form. Species of this type inhabit all the Polynesian 

 islands. It has been customary to class them together, under 

 the name of Marroccana. It will require an examination of 

 their animals, to determine their relation. I have separated 

 another species on the shape and color of its operculum. 



'■^ JVassa plicata, Pse. MSS., = dwarf far. ofoUvacea, Brug., = 

 tcenia, Gme." 



The above name being pre-occupicd, has been changed to 

 a-jyproximata. The aperture of this species belongs to tcenia^ 

 Gme. ; other parts of the shell to approximata, Pse. I have no 

 faith in cosmopolite species, or those common to widely separate 

 and distinct Eaunas. 



" Nassa microstoma, Pse., = a white var. of dcrmestina, Gld." 

 I have collected perfect specimens of the above within the 

 past few years. The following characters will serve to dis- 

 tinguish it from dermestina: Transversely strongly ribbed, 

 columella ridged, with a callosity at top. Outer lip not denticu- 

 late, but lyrate within. Banded with dark chestnut, interstices 

 between transverse ribs same color ; whorls few in number.
