FASCIOLARIA. 1 1 



acuminata ; canali elongate, angusto truncate. — Our figure 7 

 corresponds fairly with Lamarck's description of his F. ferru- 

 ginea, which, with Kiener, I regard as a variety of this 

 species with more rounded and less tuherculated whorls. 



7. TRAPEZIUM, f. 21, 22, 33, Linnceus. — Testa solida, 

 quadrilateralis, epidermide fusca induta, spiraliter rubro- 

 lineata, supra medium angulato et tuberculis magnis armato, 

 anfractu ultimo infra conspicue vel inconspicue tuber- 

 culato ; spira breviuscula, canali lato, truncate ; apertura 

 magna, intus striata et rubro lineata, margine denticulate. — 

 The extreme form fig. 21 and the rather cylindrical shell 

 f. 23, have been separated as sub-species by Jonas under 

 the names of ponderosa and Audouinii. 



8. Heynemani, f. 11, Dunker. — Testa fusco-aurantia, 

 Isevis, subpyrulata ; spira brevi, anfractibus prope suturam 

 angulatis, ad angulum tuberculis oblenge-retundis armatis, 

 supra angulum declivibus ; apertura pyrifermi, alba leviter 

 purpurea suffusa ; anfractu ultimo obscurissime bilirato. — A 

 very characteristic Cape shell, of which the only specimens I 

 have seen are much worn, and have lost the purple tints 

 from which the species may have been named. 



9. LiGNARiA, f. 18, Linnceus. — Testa angusta, recta 

 turrita fusiformis, subviride fulva, fusee fasciata lasvis ; 

 spira preducta, anfractibus angulatis, ad angulum acute 

 tuberculatis, canali brevi, recto, truncate. — This well-known 

 Mediterranean species is the F. Tarentina of Lamarck. 



10. AURANTiACA, f. 20, Lamavck. — Testa ventricosa, 

 subquadrangulata, aurantie rubroque variegata, spiraliter 

 quadriseriatim tuberculata, duplicatim sulcata, spira bre- 

 viuscula, anfractibus angulatis, ad angulum tuberculis 

 magnis munitis ; apertm-a pyrifermi, intus striata, margine 

 denticulate, canali brevi late. — Commonly called the ' Per- 

 sian vest ' according to Lamarck, without reference to its 

 locality, which is unknown. 



11. Peesica, f. 19, Reeve. — Testa quam F. aurantiaca 

 latior, sulcis magis distantibus, tuberculis majoribus, inter- 

 stitiis maculis nigrescentibus ornatis.— A much broader and 

 heavier shell than F. aurantiaca, with more distant flat- 

 tened grooves, and larger tubercles.
