fusus. 85 



ducta, turrita, anfractibus 7 angulatis, ultimo subquadrato ; 

 apertura brevi, canali brevissimo. — An interesting form de- 

 scribed by Mr. E. Smith of the British Museum. 



86. ficula, f. 88, Reeve. — Testa anguste rhomboidea, pal- 

 lide fusca, lineis rubris super costas picta, spira pyramidali, 

 anfractibus distanter plicatis, supra medium angulatis, supra 

 angulum subexcavatis, omnino spiraliter sulcatis ; apertura 

 subquadrata, labio externo denticulato ; canali brevi, lato. — 

 The distant plaits are crossed by lira? with little red bands 

 between. 



87. CRENULATus, f. 170, Sowerby. — Testa quam F. 

 robustior magis cylindrica, angustior, spira magis elevata, 

 anfractibus ad suturam tumidis, infra canaliculars, liris 

 spiralibus crenulatis, ad angidum anfractuum nodosis. — This 

 species was at first passed by as a variety of F. robustior or 

 F. ocellifera, but the elevated form of the spine and the 

 crenulation of the ridges compel the separation. 



The correct place of this species would be following F. 

 ocelliferus, No. 74. 



88. mexicanus, f. 90, Reeve. — Testa breviter fusiformis, 

 subquadrata, fulva, griseaceus, rubro longitudinaliter et spira- 

 liter inter costas fasciata ; spira subproducta, anfractibus 

 quadratis, superne angulatis, longitudinaliter nodoso-plicatis, 

 spiraliter nodoso-liratis ; canali brevi, truncato ; apertura 

 quadrata, margine crenato. — Crossed with red bands be- 

 tween the spiral lirse and the nodose longitudinal plaits. 



89. cinereus, f. 87, Say. — Testa oblongo-fusiformis, 

 grisea, spiraliter rude lirata, longitudinaliter rotunde plicata, 

 spira producta, anfractibus rotundis, prominentibus ; aper- 

 tura pyriformi, margine crenato, canali brevi, lato, truncato, 

 recto. — A plain shell of ashy white hue. 



90. norrissii, figured as Trophon, f. 36, is a more ventri- 

 cose shell than F. cinereus, but neither species is character- 

 istic of the present genus. 



91. tenuistriatus, f. 140, Sowerby. — (Type in Mr. Hanley's 

 collection from Capt. Beecbey.) — Testa parva, angusta, striata, 

 solida, alba, versus apicem subaurea ; spira subturrita, an- 

 fractibus 6, brevibus, superne angulatis, longitudinaliter 

 medio usque ad angulum superiorem rotundo-plicatis. — The 

 place of this species is next to
