This shell is of the same size, and is nearly allied to M. de- 

 spectus, hut it has the upper part of its whirls more gradually 

 sloped downwards, and has three or four transverse ridges 

 on its body-whirl, and two on the whirls of the spire ; some 

 of the longitudinal striae or plaits, M'hich Fabricius mentions, 

 are also observable in Pennant's Frontispiece, and I have 

 hardly any doubt that M. carinatus belongs to the same 

 species. Born appears to have mistaken this shell for the 

 Linnsean M. Aruanus. 



DESPECTUS. 89. Shell oblong, with the whirls ven- 

 tricose, and two transverse elevated lines ; 

 aj3erture dilated, and the beak short.

The shell which Mr. Donovan has figured, and which he says 

 answers to the Linnsean description and figure, is two inches 

 and a quarter long, and an inch and a quarter broad. Mr. 

 Donovan adds, *' at the first glance this shell appears to be 

 an intermediate kind, between Lister's shell and the Murex 

 carinatus of Pennant and ourselves : indeed the principal 

 difference we perceive between the true M. despectus and 

 Lister's shell, is that the former has the whirls of the spire 

 rather more ventricose, and distinctly marked with two 

 slightly elevated spiral lines ; from Murex carinatus it dif- 

 fers principally in the very prominent angulations of the an- 

 fractibus, where the ridges appear, and more particularly in 

 the strong depression between the upper ridge and the su- 

 ture of the whirls." 



SUBANTIQUATUS. 90. Shell oblong, with eight 

 whirls, angulated, and strongly keeled trans- 

 versely ; aperture dilated, and the beak short.
