probably correct; but this being a matter of uncertainty, it is 

 perhaps best to allow Lamarck's generally adopted identifica- 

 tion to stand. Donovan's N. nitidu seems to be the Medi- 

 terranean shell (our fig. 118); and the present species was 

 renamed because it did not appear to be rightly identified 

 with Donovan's shell. 



95. MACILENTA, f. 154, PhUippi. — Pyramidata, maculis 

 sagittatis. inter fascias fuscas variegata, umbilico angusto, 

 callo columellari fusco, infra oblique attenuato; apertura 

 castanea. 



96. JAMAiCENSis, f. 110, C. B. Ad. — Oblique subovata, 

 livida, fiammis undulatis ornata, callo columellari lato rotundo 

 castaneo-purpureo, umbilicum latum tegenti. — A more globose 

 form would have been more characteristic of this species, 

 which is remarkable for the round, broad, chestnut-coloured 

 pad covering a broad umbilicus. 



97. pisiroKMis, f. 163, Recluz. — Parva alba oblique sub- 

 globosa ; umbilico parvo, columella ad umbilicum lobata. — A 

 little white shell without distinctive characters. 



98. VENUSTULA,f. l^Q^Recluz. — Gracilis ovata pallida, lineis 

 castaneis maculisque picta, spira elevata, anfractibus convexis ; 

 apertura brevi, labio columellari lato, expanso, umbilicum 

 tegenti. — A pale buff little shell, with the last whorl swollen 

 and raised above the aperture, and the columella broadly 

 swollen so as to cover the umbilicus. 



99. NUCULA, f. 145, Reeve. — Parva sordida, subquadratim 

 globosa, columella callosa, medio lobata, umbilicum tegenti. 

 — The umbilicus is covered by the columellar rounded pad in 

 this little dull brown shell. 



100. ABBREViATA, f. 157, 158, Soivevby. — Parva, livida, 

 obscure bifasciatim maculata ; spira brevi, anfractibus apicali- 

 bus parvis rotundis ; ultimo subcylindraceo, ad suturam 

 leviter plicato, albo fasciato, apertura castanea, superne canali- 

 culata, labio externo superne depresso, tenui, labio interno 

 superne calloso, lobato, umbilicum tegenti. — This species 

 has a resemblance to several species of livid colour, but is 

 short and rather cylindrical, and has a closed operculum. 



101. Antonii, f. 128, Philippi. — Ovato-pyramidata livida, 

 triseriatim maculata, apertura semicirculari castanea; labio
