 castaueis scriptiforniibus acute angulatia frransversis notata. 

 — In 0. scripta, which is a shorter shell, the greatest ex- 

 pansion is towards the spire; in 0. litterata the shell tapers 

 towards the spiral end, and over the small reticulated mark- 

 ings are long angular writing-like markings. 



111. meecatoeia (f. 2G8, 269), Mcurrat. — Subfusiformis, 

 crassa, ventricosa, lactea vel pallide rosea, lineis angulatis 

 rubris aut griseis angulatis reticulata, ad suturam fasciculata ; 

 spira breviter conica ; columella plieis crassis paucis sub- 

 distantibus rugata, callo antico prope terminum purpureo 

 maculato, plieis perobliquis ; labio crasso, intus abraso, ex- 

 tus fusco laqueato. — A stouter shell than the normal form of 

 0. olivacea (reticulata, Lamk.). 



112. nivosa (f. 276, 472), Mcurrat. — 0. mercatorice similis, 

 sed pallida, magis cylindracea. — A full-bodied shell, with 

 narrow aperture. 



113. sceipta (f. 266, 267), Lamlc. — Oblongo-subcylindrica, 

 postice lata, antice subattenuata, subfusca, lineis grisescen- 

 tibus minute reticulata, irregulariter fasciata, sutura fascicu- 

 lata ; spira conica ; columella obsolete plicata, callo antico 

 angustissimo ; apertura intus violacea ; labio postice ex- 

 panso, subangulato. — The posterior part of the outer lip 

 tends to expansion, and the body whorl is broader at that 

 part. 



114. mustelina (f. 272, 273), Lamk. — Oblongo-cylin- 

 dracea, utrinque subtruncata, crassa, griseo-fulva, lineis 

 angulatim undulatis longitudinaliter notata; spira brevi, 

 lata, sutura acuta, punctata; columella omnino plicata, 

 postice in callum elevatum terminanti, plieis calli antici 

 paucis, validis perobliquis; apertura intus violacea; labio 

 crasso, postice elevato, intus extusque abraso. 



115. muceonata (f. 274, 275), Mcurrat. — Cylindraceo-sub- 

 conica, fulvescens, lineis rubris angulatim undulatis notata ; 

 spira, depressa ; anfractibus callosis, apice mucronato, balteo 

 subcarinato, flammtilato; columella tenuiter omnino plicata, 

 plieis calli antici latis concoloribus ; apertura intus sordide 

 alba. — Allied to 0. mustelina, but distinguished from that 

 species by its fine and close columellar plaits. The texture 

 and pattern are also different. The spire is very peculiar — 

 hence the name.
