PYRUXA. 101 



guluin concavo ; apertura subpyriformi, intus et usque ad 

 marginem sulcato, fusco lineato. — Although Lamarck de- 

 scribes this as a pale yellow shell instead of greyish-brown 

 or striped as our specimens are, the figure of Chemnitz to 

 which he refers exhibits the differences in form and sculpture 

 which distinguish P. nodosus from P.paradisiacus (citrinus, 

 Lamarck). 



8. paradipiaca, f. 24, Martini. — Testa laevis citrina tur- 

 binata, crassa ; spira brevi, planata, ultimo anfractu superne 

 obtuse angulato, supra angulum subexcavato, infra spiraliter 

 leviter striato, apertura pyriformi labio externo intus striate. 

 — This simple smooth, orange-coloured shell is undeniably 

 represented by Martini's figures 909, 910. Besides the 

 absence of regular nodules on the angle of the whorls, it has 

 a more obtuse and straight conical form. 



9. carnaeia, f. 23, Chemnitz. — Testa crassa late tur- 

 binata, fiavido-carnaria keviuscula ; spira brevi, anfractibus 

 depressis angulatis nodosis, ultimo superne biangulato, ad 

 angulum superiorem spiuis magnis crassis coronato, ad an- 

 gulum inferiorem nodis rotundis cincto, infra lirato, ad cana- 

 lem varicoso, crasso, subumbilicato. — Large and ponderous, 

 of a yellowish flesh-colour, much broader than P. citrina and 

 P.paradisiaca, with large protruding spines on the angle and 

 towards the middle of the last whorl. 



10. lactea, f. 10, Reeve. — Testa fusiformis, pallide carnea, 

 rugoso-undulatim inasqualiter lirata ; spira exserta, an- 

 fractibus angulatis, longitudinaliter plicatis, ultimo pyriformi 

 ad canalem attenuate, subumbilicato ; apertura pyriformi, 

 intus striata, margine tenui, denticulate. — Of a pale fleshy 

 tint with unequal ridges undulating over longitudinal ribs. 

 Although not so pyriform as most of the genus, it is placed 

 here on account of its general proximity to P. pugilina, P. 

 Morio. &o. 



11. pugilina, f. 11, 12, 41, Born. — Testa subfusiformis 

 ponderosa keviuscula, spiraliter leviter sulcata, rubro-fusca, 

 spira conica, anfractibus depressis angulatis, ad angulum 

 tuberculis magnis acutis coronatis, supra angulum subcon- 

 cavo-depressis, ultimo ad canalem subcoarctato, canali lato, 

 truncate. — More commonly known as P. vespertilio ; in its 

 ordinary form a broad, ponderous, mahogany- brown angularly 

 nodose pyriform shell. In the more dwarf or stunted form,
