fusus. 89 



garded F. lyratus as a form of despectus, but it is alto- 

 gether a differently textured shell, which can be distinguished 

 through all the modifications of both species. 



Note. — tornattjs, which should follow this, will be found 

 at Sp. 97. 



108. cumingii, f. 109, Crosse. — Testa angulatim subglo- 

 bosa, spiraliter lirata, fulva, fusco fasciatim picta, ad angu- 

 lum anfractuum nodulis exfoliatis, fornicatis coronata ; spira 

 brevi, anfractibus angulatis depressis ; ultimo ventricosis- 

 simo, apertura lata, superne angulata, canali brevi, tortuo. 

 — A bulbous and very ventricose, although angular shell, 

 in some respects resembling some varieties of F. de- 

 spectus. 



109. satuenus, f. 104, 110, 123, 126, Martyn— Testa 

 crassa, rudis, fumoso-fusca, sublsevigata, ovato-fusiformis ; 

 spira brevi, anfractibus 5 plerumque angulatis, interdum 

 nodosis, superne planulatim declivibus, ultimo magno, ventri- 

 coso, interdum costis crassis lirato, interdum bulboso ex- 

 foliate, canali brevi, lato, plerumque tortuo. — A thick, 

 coarse, dull brown northern species subject to great variations 

 of form, among which figure 126, fornicatus Gruel., and 104 

 may be considered the more normal. None of the forms are 

 striated, as in F. antiquus, and they all present more or less 

 flattened slopes from the suture. 



110. kelletii, f. 108, Forbes. — Testa trapezoidea, solida, 

 alba, spiraliter striata ; spira pyramidata ; anfractibus su- 

 perne declivibus, infra medium angulatis, ad angulum nodo- 

 sis ; apertura subquadrata. — Angular, solid, and having 

 the whorls knobbed on the angles. 



111. heeos, f. 120, Gray. — Testa pallide fulva vel ferru- 

 gineo-fusca, elongato-subovata, lsevi ; spira producta, an- 

 fractibus 7, quadrato angulatis, elevatis, ad angulum inagqua- 

 liter plerumque distanter nodoso-plicatis, ultimo ventricoso, 

 apertura pyriformi, canali brevi, aperto, subtruncato. — The 

 whorls are elevated in a peculiarly angular manner from the 

 suture. 



112. abthyriticus, f. 121, Valenciennes. — Testa saturno 

 similis sed spiraliter leviter striatis, anfractibus superne 

 versus suturam convexis, undulatim tuberosis, apertura intus 

 subpurpurea, interne tenuiter lirata. — I cannot feel at all 

 sure that this species is rightly distinguished from F. satur-
