CANCELLARTA. 67 



C. SPENGLERIANA, Desh. PI. 1, figs. 2, 3, 4, 5. 



Whorls spirally linearly grooved ; yellow-brown, tinged with 

 chestnut, particularly on the shoulder, body-whorl often light- 

 banded in the middle. Length, 1-5-2-25 inches. 



China, Japan, Philippines, Australia. 



The synonyms are C. Tritonis, Sowb. (fig. 3), and C. undu- 

 lata, Sowb. (figs. 4, 5). The latter has usually been considered 

 a distinct species, but in a series of specimens the differential 

 characters merge. 



The animal is thus described by Mr. Arthur Adams : " Tenta- 

 cles broad, flat, triangularly subulate, wide apart, separated by 

 the base of the retractile proboscis. The eyes are small and 

 black, and are placed on slight tubercles at the outer bases of 

 the tentacles. The mantle is furnished with a small siphonal 

 fold. The foot is large, tiat, truncate in front, with short side- 

 angles, and acuminate and produced behind. 



" The tentacles of this species are rendered dark nearly as far 

 as the eyes by close-set small red-brown dots ; the siphonal fold 

 of the mantle is sparsely spotted with the same ; both dorsum 

 and sole of the foot are reticulate with red-brown lines, and 

 dotted with the same color. 



" The animal is very shy, rarely showing more than the tips 

 of the tentacles beyond the front edge of the shell. It has the 

 power of considerably extending the fore part of the foot, 

 using it as an exploring organ " (Ann. Mag. N. Hist., 3d ser., 

 xiii, 143). 



C. BUCCINOIDES, Sowb. PI. 1, figs. 6-8. 



Flesh-color to dark chocolate, frequently white-banded on the 

 middle of the body-whorl ; rudely decussated by longitudinal 

 and spiral ribs, the intersections often nodulous. 



Length, 1-5-2 inches. 



West Coast of Central America. 

 C. CORROSA, Reeve. PI. 1 , fig. 9. 



Whorls latticed by longitudinal and spiral ridges, <the inter- 

 sections prickly, narrowly umbilicated. Light fulvous. 



Length, 23 mill. China Seas. 



This was originally described by Adams as C. clathrata, a 

 name preoccupied by Lamarck.
