lantibus. 05s. This common shell has been generally accepted as 

 the Trochus perspectivus of Linnaeus. Of the many figures cited 

 by that author in the tenth or standard edition of his ' Systema/ 

 not one represents it ; and in the twelfth, or final edition only one 

 (Seba, iii. pi. 40, f. 1, 2). Hinds, whose ideal of the Linna?an 

 species was the S. maximum, described this species from a rather 

 elevated abnormal specimen. 



3. maximum, (f. 5, 0), Phil. — T. depresso-conica, sulcis confertis 

 obliquis (corpore lrevi excepto) radiata. Anfractus, infra suturam 

 latam, sulcis profundis 2 (quorum superior est latior), ct super 

 cingulum suprasuturale, quod (etiamque carina, basis cingula, 

 zonaque superior) fusco-rufescente et albido est articulatum, aliis 

 tenuioribus obscuris instrueti. Area; media? fulvee; apicem versus 

 cinereas, pallido violaceo tinctse. Sulcus peripneriae superior 

 latus, filis 1-2 divisus; inferior filosus, satisque latus. Basis 

 area media plerumque marginem exteriorem versus subretusa; 

 interiorem versus maculis subremotis brunneis notatum subpla- 

 nulata, et sa;pius radiatim crasse sulco-plicata. Crenae umbilici 

 amplissimi permultae, vix pergrandes, albre seu pallidas, aliquando 

 sparsim maculatre. Obs. The deeper the spiral sulci, the more 

 elevated are the belts. The second zone is never articulated. 



4. modestum, (f. 11, 12, 27, 28), Phil. — T. depresso-conica, 

 radiatim sulcata (corpore losvi excepto). Anfractus superne bis 

 longitudinaliter suicati ; vitta superior angusta, alba, vel brunneo 

 remote maculata, vel brunneo pallidiorc confertius nebulosa ; vitta 

 inferior brunnea, et ali(juantulum latior. Area media lata, fulva ; 

 cingulum super suturam angustam vel brunneum (aliquando su- 

 perne tantum), vel brunneo pallidiore et saturatiore subarticu- 

 latum. Carina albida, vel strigis fulvis perangustis ornata, vel 

 brunneo remotissime subarticulata. Sulcus peripheralis angustus 

 unifilosus. Basis vel tota immaculata, vel cingula ejus brunneo 

 remotissime articulata, et margo interior areas medise lfevigata; 

 (aut sulcis obsoletis radiatae) maculis linearibus brunneis pictus. 

 Sulcus inter carinam et cingulum proximum basale satis latus, 

 unifilosus. Umbilicus (et crenae ejus alba; satisque multse) haud 

 permagnus. OLs. Mr. Taylor possesses an example which is devoid 

 of the second spiral groove. 



5. quadriceps (f. 3, 4, 25, 26), Hinds. — T. depresso-conica ; 

 sutura conspicuecanaliculata. Anfractus omnes sulcis 3 spiralibns 

 crassis (infimo pracsertim) divisi, et sulcis subcontiguis radiantibus 

 (nisi in anl'ractu ultimo) crasse decussati. Vitta prima et quarta 

 brunneo et albido (vel pallide fulvo) subremote articulata; ; vitta
