distantibus, alternis, ad latera late expansis, subreflexis ; area ex- 

 cavata; lunula lined profunda circumscripta. 



Like A. juvenilis and A. scalaris, but witb the ridges laminated ; 

 some ending suddenly and others spread out into broad reflected 

 laminse at the sides. Fig. 87 represents a much less broadly 

 laminated variety.

Art. testa, orbiculari, subventricosa, albida, fusco-purpurascente, 

 late triradiata, omnino rufo pallidt; literata, intus purpureo-tincta, 

 concentrice costellata; costellis sub distantibus, elevato-laminatis, 

 ad latera paucioribus, acutiusculis ; area ligamenti acute excavata, 

 valvse dextra laminata, altera plana, ; lunula rotundata, impressa, 

 purpurea. 



Rather orbicular and ventricose, beautifully variegated with 

 purplish interrupted rays and spots, and having the ribs elevated, 

 rather distant, elevated and laminated, thinner and fewer at the 

 sides.

73. Artemis lirata (pi. cxliv. f. 85), Sowerby, jun. A. 

 variegata, var., Reeve, Conch. Icon. Art. f. 33 a. 



Art. testa suborbiculari, compressa, albida, fusco radiatim lite- 

 rata, concentrice costellis distantibus elevatis continuis lirata ; 

 lunula impressa, suboblonga ; area ligamenti lineari, valvse si- 

 nistra plana, valva? dextra? laminata. 



Platter than A. variegata, with the concentric ridges more dis- 

 tant and continuous, and all traces of the purple colouring are 

 lost, only pure brown angular markings remaining. This species 

 looks so different from A. variegata that one is compelled to se- 

 parate it notwithstanding the existence of intermediate varieties. 



Cagayan, isl. of Mindoro, Philippines. Cuming. 



74. Artemis lenticularis (pi. cxliv. f. 81), Soiverby, jun. 

 A. variegata, var., Reeve. Artemis, f. 29 b, 33 c. 



Art. testa lenticulari, compressa, pallide fulva, fusco-radiata et 

 literata, concentrice confertim costellata ; area, ligamenti vix ex- 

 cavata ; lunula impressa.
