of C. acutangulus of Chemnitz. The shell described and figured by 

 that author (Conch.-Cab. vol. xi. p. 59, pi. 182. figs. 1772-3) is very 

 much more slender than the form referred to it by the two above- 

 mentioned writers, and has simple non-coronated margins to the 

 whorls of the spire. 



The C. acutangulus of Kiener differs from the typical form of 

 C. turriculatus merely in being more brightly coloured. 



The C. acutangulus, Reeve (Conch. Icon. pi. 37. fig. 200), appears 

 to be a third species, and although agreeing with Kiener's shell 

 as regards form, differs in having a smooth non-tuberculated spire.

G.fioridus, Sowerby, Thesaurus, frontispiece, f. 558, is unques- 

 tionably merely a slight variety of this well-known species, and 

 bears no relationship whatever to C. tulipa, with which it is 

 erroneously united by Weinkauff (Conch.-Cab. p. ISO, and Jahr- 

 biich. deutsch. mal. Gesellsch. 1874, p. 285). 



10. Conus martensi. (Plate XLIV. fig. A.) 



Shell small, turbinate, much narrowed towards the base or front, 

 of an orange colour, rather paler upon the spire. Whorls about 

 10, flat-topped and a little sloping, raised somewhat above one 

 another, concentrically three-grooved, separated by a deepish suture. 

 Last whorl subacutely angled above, then a trifle convex at the 

 sides, and being much attenuated anteriorly has a somewhat piri- 

 form appearance ; it is sculptured with fine lines of growth and 

 transverse indistinct striae or shallow grooves, which around the
