from F. Tasmaniensis, Ad. and Ang. wliicli is pyrifdrm. Its 

 nearest representative is F. muricalits Montague (in Testacea 

 Britannica as Murex m.), but in that species the costse are 

 much more distinct. 



SiPHONALiA CLARKEi. B. testa fai^va, turrita, suhfusiformi, 

 livida ; mciculis rufo-fuscis sub peripheriam ornata ; anfractibus (6), de- 

 clivis, superne angulatis, regione suttirali concava ; costis radiantibus, 

 (in ult. anfr. 12) ohtusis, rotuiidatis, infra ohsoletis, interstitiis con- 

 cavis costis paulo superantibus ; lirnlis spiraliljus superne et supra castas 

 obsoletis ; canali hrevi, vix curvato ; apertura ovata; labro intus 

 dentato ; labio inconspicuo. Long. 27. Lat. 9. 



S. shell small, turretted, sub fusiform, livid (or brown — it 

 varies in color much as Columhella semiconvexd) with reddish 

 brown spots under the periphery ; whorls sloping, angulate 

 above, and concave at the suture ; radiately ribbed (ribs 12 in 

 last whorl) ribs obtuse, rounded, obsolete below, and narrower 

 than the interstices, spirally lirate ; lirse obsolete above and on 

 the ribs ; canal short sloping, but scarcely curved ; aperture 

 ovate ; labrum toothed within ; lip inconspicuous. 



From the very full and concise descriptions of Siphonalia 

 fascozonata, by Mr. Angas "Zool, Pi'oc. ]865," p. 56, our only 

 Australian species, I am able to pronounce this species distinct 

 and new. It is much larger, the ribs more numerous, the 

 color livid instead of white, and the lirse obsolete or absent, 

 and lip toothed within. The brown spots are often deeply 

 shaded at the summit of the ribs, and form a kind of fascia on 

 the upper whorls. The labrum is often thickened into a kind 

 of varix. At Long Bay, D'Entrecasteaux Channel, Legrand 

 and Atkinson. 



I have dedicated this interesting species to my dear friend 

 and fellow labourer, the Eev. W. B. Clarke, P.G-.S., &c, so 

 long and eminently connected with the history of Australian 

 geology. 



SiPHONAXiA TURRITA, U.S. S.t. fiisiformi-elougata, castanea vel 

 livida ; superne raaculis rufo-fulvis zonata, postice lineis subtillissimis 

 punctatis rufo-castaneis cincta ; spira elata, costata ; anfractibus 7, con- 

 vexis ; ultimo obsolete nodoso-costato ; apertura ovata, intus macidata 

 et fasciata, fasciis interuptis ; labro acuto ; labio concavo ; canali 

 oblique elongato. Long. 16. Lat. 7. 



S. shell fusiformly elongate, chestnut or livid, zoned above 

 with reddish brown spots, and posteriorly girdled with very 

 fine lines of reddish chestnut points ; spire elevated, ribbed ; 

 whorls 7, convex, last obsoletely nodosely ribbed ; aperture 

 ovate, spotted and l:>anded with interrupted color within ; 

 outer lip acute ; inner lip concave ; canal obliquely elongated. 



Long Bay, rare, Coll. Legrand. A shell very closely re- 

 sembling S. clarkei, but more fusiform with a longer canal, and
