101. texuistriata (f. Ill), Rve. — Oblonga, gibba, alba, 

 apice versus marginem auticum inclinata, prope apicem minute 

 cancellata, versus marginem minute radiatirn scabroso-striata ; 

 foramine magno, rotundo. Obs. An oblong gibbous white shell, 

 very short, anteriorly cancellated near the apex, the radiate ribs 

 thinning out into even striae near the basal margin. The foramen 

 is very large and round. 



102. pileopsides (f. 120, 121), Rve. — Oblique gibbosa; apice 

 ultra marginem basalem incurvato ; pallide fulva, prope apicem 

 rubro tincta ; costis crenulatis, rotundis, quarum alternis depressis 

 radiata ; foramine elongato, declinato. Obs. The name is happily 

 chosen to express the curving of the apex and its leaning beyond 

 the front basal margin. 



103. gibba (f. 114, 16S), Philippi. — Oblonga, alba, convexa, 

 liris concentricis et costis noduliferis rndiantibus cancellata; fora- 

 mine oblongo ; variat subolivacea, fasciis viridis radiata. Obs. 

 Distinguished by Philippi from the following by the greater con- 

 vexity of its back and sides. F. Candida, of the ' Con. 111.' pro- 

 bably belongs to this. 



104. gibbekula (f. 113, 117), Lamk. — Oblonga, postice at- 

 tenuate, alba vel variegata, cancellata; lateribus depressis; margine 

 basali arcuato ; foramine oblongo. Obs. This species has the 

 sides and back more depressed, the basal margin more arched, and 

 the anterior more narrowed than the preceding. 



105. granifera (f. 165), Pease. — F. gibbte simili, sed multo 

 breviore. Obs. Much shorter than F. gibba. 



106. arctjata (f. 163, 164), Sowb. G. B. 2.— Parva, alba, 

 fulvo radiata, radiatirn minute striata, antice angusta ; apice versus 

 marginem anticum declinato ; dorso gibboso, arcuato ; margine 

 ventrali arcuato ; foramine parvo. Obs. Small, white, with fawn- 

 coloured rays, much inclining forward, and having a curiously- 

 arched and gibbous back. 



107. uiNUTA (f. 169), Sou-b. G.B. 2.— Parva, elongata, dorso 

 arcuata, fulvo- virescente, radiatirn linearum fasciculi* fasciata, con- 

 centrice lirata, costellis crebris minute noduliferis radiata; intus 

 griseo ; margine crenulato; foramine parvo, nigro-marginato, prope 

 marginem anticum posito. Obs. This little shell was figured in 

 the ' Conchological Illustrations/ and agrees well with Lamarck's 

 description of the species. Mr. Pteve's subsequently-imposed 

 name, F. gemmulata. must therefore be dropped.
