PYItULA. 103 



pyrula may be compared to a much lengthened and refined 

 P. pugilina. 



17. elongata, f. 8, Lamar ck. — Testa gracillima pallide 

 flavido-castanea, lasvis, leviter spiraliter striata ; anfractihus 

 superioribus angulatis, longitudinaliter plicatis ad angulum 

 acute nodosis, ultimo pyriformi, attenuato, canali elongato, 

 sensim angustato. — The most slender of all the Pyrulse except- 

 ing P. tessellata. 



18. tessellata, f. 6, Kiener. — Testa hevissima, volutse- 

 formis, gracillima, anfractibus brevibus, subrotundatis, ultimo 

 perelongato, maculatis fuscis castaneis seriatim picto, an- 

 tice sensim attenuato. — Much like a slender volute inform, 

 with rows of chestnut spots. 



19. tabttlata, f. 17, Baird.— Testa fusiformis, subventri- 

 cosa, alba ; spira producta, scalariformi, anfractibus ad sutur- 

 am planatis, angulatis ad angulum squamis elevatis angulatis 

 inaequalibus coronatis, infra angulum ventricosis, spiraliter 

 distanter serrato-li rat is, longitudinaliter acute striatis ; ultimo 

 maguo, pyriformi sensim in canalem decurrenti, apertura 

 pyriformi, elongata, margine crenato. — -Although the last 

 whorl is pyriform, I should hesitate in placing the species in 

 this genus, but for its apparent affinity to P. corona, as seen 

 in the tabulated space between the suture and the coronated 

 ridge which borders it. 



20. corona, f. 15, 16, Chemnitz. — Testa subpyriformis, 

 crassa, fusco-nigrescens albo bifasciata, sublsevigata, spira- 

 liter leviter subsulcata ; spira breviuscula, anfractibus 5 

 scalariformibus, superne angulatis, inter angula et suturam 

 plano-excavatis,ad angulum spinisexfoliatismagnisacutis albis 

 coronatis ; ultimo pyriformi ad canalem lato, subumbilicato 

 ad marginem serrato ; apertura pyriformi, intus fusco-pur- 

 purascente picta. — It is a matter of surprise that Lamarck 

 should have placed this species in the genus Fusus, while his 

 P. Vespertilio finds a place here, P. corona being by far 

 the most pear-shaped species of the two. The raised leaflets, 

 forming a kind of corona on the angle, the excavated area 

 at the suture, and the deep colour relieved by bands of 

 white are characteristic and distinctive. 



21. melongena, f. 21, 22, Linnaeus (Murex) — Testa 

 brevi, late pyriformi, crassa, cseruleo-fusca, albo fasciata, 

 leviter sulcata ; spira brevi, anfractibus parvis, longitu-
