160 STYLIFER. 



apertuia obliqua, margine supeine inflexo. — The last whorl 

 but one of the spire being rather raised and inflated, gives 

 this species a more pyramidal appearance than other globose 

 forms. 



5. JAPONicus, f. 17, A. Adams. — S. diibio similis, rectius- 

 culus ; ultimo anfractu ad suturam tumido ; columella soli- 

 diuscula. — The form is nearly the same as in the preceding, 

 the last whorl being a little tumid near the suture. The 

 columella is solid. 



6. GuENTHEBi, f. 1, Angas. — Globoso-pyramidatus ; 

 spira elata, apice flexuoso, ultimo anfractu inflato, prope 

 suturam subplanato, deinde declivi, infra late rotunda, sinu 

 columellari late sinuate. — This and the following seem to 

 combine the characters of the globose and subulate species. 

 A slight leaning shelf is seen on the upper part of the 

 whorls. 



7. CuMiNGiANUS, f. 2, A. Adams? — Infra globosus, spira 

 elevata pyramidata ; anfractibus brevibus gradatim crescen- 

 tibus, apice reflexo ; ultimo maximo. — The spire is more 

 elevated and, consisting of more numerous gradually increased 

 whorls than in the last species, presents a greater contrast 

 between the two parts of the shell. 



8. Barronii, f. \(S,A. Adams. — Ovatus, anfractibus duobus 

 ultimis subcylindricis, prope suturam valide angulatis, infra 

 angulum subcontractis ; apertura subquadrata ; apice styli- 

 formi. — The form is peculiar, having a produced angular 

 ledge at the upper part of the two last whorls. 



9. EBURNEUS, f. 8, Deshayes. — Ovato-pyramidatus, alba 

 polita ; apice brevi, acuto, anfractibus paucis gradatim cre- 

 scentibus, ultimo rotunde subovato. — Of an ovate-globose 

 form, different from the other species, but as found upon 

 Asteroids and Echini in the Mauritius, pronounced by 

 Deshayes to be Stylifers. 



10. ATTENUATUS, f. 10, Sowerby. — Parvus tenuis angustis- 

 simus rectilateralis ; apice ad latus sinistrum inclinato, acutis- 

 simo ; apertura subtrigona. — Extremely small and narrow. 



11. CORALLINUS, f. 11, Ckemnltz. — Quam S. attenuatus 

 infra latior, anfractibus parviusculis apice ad latus dextrum 

 inclinato. — The lower whorls are more pyramidal than S. atte- 

 nuatus, and the apex turned slightly in the other direction.
