multo magis elevata ; costis tenuioribus. Obs. The ribs are thinner 

 and the shell more elevated and conical than F. Listen; these 

 with the Australian habitat may justify the distinction. 



75. reticulata (f. 112), Doiwv. — Oblonga, antice attenuate, 

 depressa, costis parvis moniliferis insequalibus et liris coucentricis 

 cancellata, pallide fulva, viridi vel fusco radiata; intus alba; mar- 

 gine denticulate ; lateribus arcuatis ; foramine parvo, multo supra 

 medium posito, declinato. Obs. This cancellated species has some 

 of the front ribs more prominent than the others. The basal 

 margin is arched at the sides. 



76. costaria (f. 117), Desk. — F. reticulata simili, sed costis 

 et liris minoribus, magis aequalibus ; margine basali ad latera recto. 

 Obs. The sculpture is finer than in F. reticulata, the ribs more 

 regular, and the basal margin not arched. 



77. Singaporensis (f. 118, 119). — Oblongo-ovali, depressa, 

 alba vel pallide fulva, interruptim fusco seu griseo radiatim fas- 

 ciata, suharcuata, regulariter cancellata; foramine ovali, multo 

 supra medium posito, antice declinato. Obs. Like F. reticulata, 

 but of a more oval form and more regular cancellation. 



7S. latiora (f. — omitted), Sowb. G. B. 2. — Quam F. Sin- 

 gaporensis multo latiore. Obs. I omitted a figure of this, not 

 intending to distinguish it from the preceding, than which, how- 

 ever, it is much broader. 



79. australis (f. 158), Kranss. — Oblongo-ovali, depressa, pos- 

 tice convexa, costellis aequalibus moniliferis cum alteris mino- 

 ribus intermediis et liris miuutis coucentricis cancellata. Obs. 

 The cancellation is much more close and regular than in F. Singa- 

 porensis, and besides the long radiate ribs, there are others inter- 

 mediate which, beginning later, are shorter. 



80. lineata (f. 134, 135), Sowb. — Ovali, antice subattenuata, 

 declivi postice convexa, regulariter cancellata ; costellis nonnullis, 

 moniliferis, rubris ; intus alba ; margine duplicatim denticulato ; 

 foramine ovali, antice posito declivi. Obs. Although first figured 

 from a smaller specimen, there can be no doubt of the identity of 

 this shell, to which the name subsequently given by Mr. Reeve 

 was therefore unnecessary. A few of the beaded ribs are a little 

 prominent and coloured red, and although this is not the case with 

 the larger variety which is obscurely rayed with clouded green, 

 yet the more prominent ribs are present undistinguished by the 

 red line. 



81. densiclathrata (f. 157), Rve. — Ovali, subdepressa, co-
