FUSUS regiilaris. 



TAB. CCCCXXIII.— >^. 1. 



Syn. Murex regiilaris o/'7^aZ». 187./. 2. Murex 

 antiquus, Branderf. 74. sed non Linn. 



jL he small specimens of this species figured formerly, 

 were not suspected to belong to Brander's M. antiquus, 

 but a series presented by the Rev. T. Cooke, several of 

 which agree exactly with Brander's figure and descrip- 

 tion, prove that they are the same. 



The three species figured upon the same plate, (tab. 

 187.) and called Murices, certainly belong to the Genus 

 Fusus, as it is at present established by Lamarck; they 

 are all remarkable for the square shape of the elevated- 

 lines that cross them, and are not met with abroad. 



FUSUS complanatus. ^ 



TAB. CCCCXXIIL— /^5. 2 and 3. 



Spec. Char. Ovato-fusiform, pointed, costa- 

 ted, and transversely striated ; superior 

 edges of the whorls elevated and pressed 

 upon the spire ; striae contiguous ; columel- 

 la curved; 



J. HERE are two varieties of this Fusus, one of them has 

 the costae much more prominent than the other; in both 

 the obtuse, slightly elevated ridges between the strict 

 give the surfaces a uniformity of character by which the 

 species is well distingiished. The beak is shorter than 

 the spire, and a little expanded ; there is no appearance 

 of a fold upon the columella, by which it is distinguished 

 from several nearly allied French species. 



Both varieties were found plentifully at Highgate^ 

 while the road through the Hill was in progress. 



Fig. 3, represents tlie costated variety.
