lines below, and three at the shoulder-angle ; marked with brown 

 flames and white and brown dots in revolving series. 

 Length, 1-25 inches. 



Moreton Bay, Australia. 



C. ACUMINATUS, Hwass. PL 8, fig. 54 ; PL 9, fig. 55. 



Spire channeled, concavely elevated ; yellowish or pink-white, 

 with a network of chestnut or chocolate ; sometimes indistinctly 

 banded, with lines of spots on the bands; aperture generally 

 rose-tinted. Length, 1 '5-1 '75 inches. 



Red Sea. 



Besides being smaller, the pattern of coloring on this shell 

 differs from that of C. Amadis by being reticulated rather than 

 triangularly spotted. C. insignis, Sowb., is a synonym. 



Yar. CUNEATUS, Sowb. PL 9, fig. 55. 



Shell not reticulated ; pink-white, with two pale yellow bands 

 and a very few chestnut spots on the body-whorl and spire ; 

 aperture rosy. At first sight appears distinct. Jickeli has 

 figured it as a variety, in his paper on the Cones of the Red Sea. 



C. SCHECH, Jickeli. PL 9, fig. 56. 



Shell narrow; yellowish, reticulated with chestnut or choco- 

 late, witli two broad, spotted dark bands. Length, 1-1*5 inches. 



Eed Sea. 



Is perhaps only an extreme variety of C. acuminatus, Hwass. 

 It is the C. Neptunus of Kiener (not Reeve), and is figured by 

 Sowerby as a variety of C. Amadis. 



C. NODULOSUS, Sowb. PL 9, fig. 59. 



Shell with elevated, channeled spire ; yellowish, delicately and 

 openly reticulated with chestnut ; aperture roseate. 

 Length, 2 inches. 



Australia (Taylor collection). 



The locality is very doubtful, as is also the claim of the shell 

 to recognition as a species distinct from C. acuminatus. 



C. LUCTIFICUS, Reeve. PL 9, fig. 60. 



Spire rather elevated, channeled ; body-whorl with straight 

 sides, closely grooved towards the base ; whitish, stained and 

 longitudinally streaked with reddish brown, and encircled with
