156 DELPHINULA. 



depresso angalatim squamoso, anfractibus infra an^ulum 

 seriatim spiniferis ; umbilico parviusculo. — Not unlike a 

 Trochus of the Calcar division. 



14. MURiCATA, p. 18, Reeve. — Subconica, pallida fulva, 

 rubro lineata et maculata ; infra angulum carinis tribus 

 prominentibus spiniferis cincta. — Differing from D. radiata 

 in being more stout and Turbo-like, with the top row of 

 projections not conspicuously larger than the others. 



Genus LIOTIA, Rang. 



Testa turbinata crassiuscula varie sculpta, albida, non 

 nacrea, umbilicata ; apertura rotunda ; operculum corneum 

 multispirale. — The shells of this genus might be placed with 

 the Delphinulse, but are not pearly. Most of them are more 

 closely spiral than the true Delphinute, and have a smaller 

 umbilicus. 



15. Peronii, f. 19, Kiener. — Subrotundato-depressa, seria- 

 tim foveolata, superne varicosa ; anfractibus superne angulatis, 

 undulatim carinatis ; apertura extus laqueata, intus subcon- 

 tracta, umbilico parvo. — Very curiously pitted, particularly 

 near the margin of the umbilicus. The varices vary, and in 

 some specimens commencing at the suture do not reach 

 farther than the upper angle of the whorl. 



16. ciDARis, f. 20, Reeve. — Depresso-subglobosa multivari- 

 cosa, varicibus rotundis distinctis per liras spirales junctis. — 

 The rather frequent and distinct varices are united by several 

 spiral ridges. 



17. SCALAROIDES, f. 24, Reeve. — Globosa, anfractibus vari- 

 cosis ; varicibus magnis paucis. — In this species the large 

 varices are not united by spiral ribs as in the last. 



18. VARICOSA, f. 25, Reeve. — Angulato-globosa, omnino 

 foveolata, varicosa ; varicibus prominentibus puncturatis ;
