 radiatim liratd et striatd, liris spinosis, spinis forli- 

 bus, suberectis, striis eximie mwricatis ; fuscesce/i/t'-

 shaped, radiately ridged and striated, ridges spined, 

 spines strong, rather erect, strife delicately prickled ; 

 brownish rose, whitish towards the umbo, dotted

 The allied Spondylus. Shell somewhat triangularly

 with rather long promiscuously twisted scales, in- 

 terstices with five rows of prickles ; brownish-purple, 

 dotted with rose about the umbo, scales wbit-e.

 ground, which in the present species has a more purple 

 tone, while the umbo is rose-spotted. The chief diiference 

 is in the more rudely angular form of this shell.

Mr. Sowerby refers the shell here represented to tli( 



above-cited figure of Chemnitz, but it does not agree with 



it satisfactorily.
