distant spots near the suture, and another of longitudinal spots on 

 the middle of the body-whorl. 



3. stiiiolatus (f. 5, 6), Porro. — T. ventricosa, pallida, fasciis 

 fuscis interruptis tribus ; striis crebris, numerosis, alteris rarioribus 

 magis elevatis ; labro angusto, tenui. 06s. More like P. lessel- 

 latiis than any other, but the lip is thin and very little expanded ; 

 in striation it resembles P. auritus. 



4. Philippianus (f. 21, 22), Gredler. — T. P. tessellaio similis 

 sed gracilior ; labro duplicate). 06s. In the striation and general 

 appearance this resembles the last, but is a much narrower shell, 

 with the inner edge of the aperture forming a ring raised above 

 the flattened outer portion. The middle row of spots not so 

 linear. 



5. scalarinus (f. 17, 18),Filla. — T. P. Philippiano similis, sed 

 labro simplici angusto ; macularum seriebus duabus, et fascia 

 basali. 06s. The lip is duplicated and very little expanded. 

 There is a band of brown colour near the base of the last whorl, 

 besides the two rows of spots above. 



6. patulus (f. 11, 12), Drop. — T. elongata, polita, fusco- 

 plumbea ; striis tenuissimis, crebris, versus anfractum ultimum sub- 

 evanidis; a pert lira subrotunda, patula, labro duplicate. 06s. 

 Towards the lower whorls the very fine striae become faint and 

 almost disappear; the body of the whorl appearing polished and 

 shining. 



7. tersalinus (f. 13, 11), Zehjl. — T. quam P. patulus bre- 

 vior, fasciatim maculata. 06s. Shorter than P. patulus, and 

 having three bands of spots. 



8. obscurus (f. 3, 4), Brap. — T. subcylindrica, fusco-plum- 

 bea, fusco-rubescente triseriatim maculata ; striis teuuibus, crebris ; 

 labro paululum expanso, vix angulato. 06s. A rather pupseform 

 species, with two rows of spots and a band near the base of the 

 last whorl. 



9. maculatis (f. 7, 8), Drop. — T. quam P. obscurus magis 

 angusta, labro baud tantum expanso. 06s. This species — or it 

 may be only variety — is narrower, with less expanded lip than 

 P. o6scurus. P. apprimus is a variety of this. 



10. cineuascens (f. 9, 10). — T. P. o6scuro similis, sed imma- 

 culata; striis crassioribus. 06s. The strioe in the upper whorls
