1 00 PYRtJLA. 



3. orbignyi, f. 42, Reeve (Purpura). — Testa breviter tur- 

 binata, epidermide crasso subserrato induta, liris acute an- 

 gulatis solidis distantibus spiralibus cincta ; spira breviter 

 turrita ; apertura lata, labio interno crassiuseulo, labio 

 esterno acute laqueato. — The distant ridges are sharp 

 enough to be considered keels. The shell is hardly pyriform 

 enovigh for this genus, and is therefore included with much 

 doubt. 



3*. pallida, f. 37, 38, Broderip. — Testa subovata sub- 

 ventricosa, nodulosa, epidermide induta, apertura elongata 

 pyriformi, intus pallide violacea, margine crenato. 



4. galeodes, f. 18, 20, Lamarck. — Testa griseo-fusca 

 solida rubro lineata, angulatim turbinata, spiraliter inasqua- 

 liter striata et lirata ; spira breviuscula, acuta, anfractibus 

 superne declivibus, angulatis, ad suturam spinoso-squamatis, 

 ad angulum subnodosis subcarinatis, ultimo ad canalem spira- 

 liter squamoso-varicoso, subumbilicato ; apertura pyriformi 

 postice subcanaliculata. — A brown angular turbinated shell 

 with red lines on the grooves or ridges. The lower part of the 

 last whorl is varicose, and the upper part joins the suture 

 with pointed scales. 



5. angplata, f. 19, Lamk. — Testa griseo-alba, F. galeodi 

 simili sed ad suturam baud squamata, ad angulum nodoso- 

 spinosa, infra medium etiam subspinosa. — The want of spine- 

 like scales at the suture, and the presence of spines on the 

 angle and below the middle of the whorls may possibly be 

 admitted as reasons for separating the present from the 

 preceding species. 



6. squamosa, f. 13, 14, Lamarck. — Testa cretacea pallida 

 F. galeodi similis, sed ad suturam squamis rotundis, ad 

 angulurn duplicatim spinoso-squamata infra medium plus 

 minusve spinosa. — This and the two preceding species might 

 be united as only representing variations in the disposition 

 of the scales and spines such as are not uncommon in this 

 very variable genus. Yet the comparative lightness of shell 

 and the roundness of the whorls give to P. squamosa a dif- 

 ferent general aspect. 



7. nodosa, f. 25, 26, Chemnitz. — Testa lasvis conica grisea 

 fulvescens griseo-fusco fasciata ; spira depressa, conica, ultimo 

 anfractu superne angulato, ad angulum nodosa, supra an-
