MUREX. 707 



tinged with violet ; the aperture is not toothed, by which it 

 may be at once distinguished from M. Riciuus. 



MANCiNELLA. 50. Shell ovate, and transversely stri- 

 ated with four rows of obsolete spines ; outer 

 lip toothless, and the pillar umbilicated, tlat- 

 tish, and striated.

Humphreys. 

 Shell about an inch and three-quarters long, and an inch and a 

 quarter broad ; the colour is brownish or yellowish white, 

 with the tubercles black or red, and the pillar-lip yellow 

 with tawny strias. It is too nearly allied to Buccinum hcema- 

 stomum to be placed in a different Genus, and most of the 

 shells in this division agree better with the Luinaean defini- 

 tion of Buccinum than with that of Murex. I rather doubt 

 whether the Murex Pyrum of Chemnitz, xi. p. 122. t. 192. 

 f. 1847 and 1848, is more than a Variety of this species. 



HIPPOCASTANUM. 51. Shell ovate, transversely 

 striated, and armed with four rows of coni- 

 cal spines ; pillar-lip sinuated, and the throat 

 striated.
