ATILIA. 149 



C. MON1L1FERA, Sowb. PI. 53, fig. 100. 



Shell oblong-acuminated, with well-marked sutures and some- 

 what rounded whorls ; longitudinally ribbed, crossed and decus- 

 sated or tuberculated by revolving riblets ; white, chestnut- 

 spotted on the ribs, leaving a central white band ; aperture rather 



narrow, denticulated within. Length, 5 mill. 



West Indies. 

 Reeve's figure of this species is very inaccurate. 



C. MANGELIOIDES, Reeve. PL 53, fig. 1. 



Shell fusiform, rather solid, longitudinally strongly ribbed ; 

 yellowish, sprinkled with orange-brown spots ; whorls numerous, 

 flatly convex, sutures impressed, the last whorl produced into a 

 canal ; aperture small, lip varicose, denticulated within. 



Length, 8 mill. 



West Indies. 



I reproduce Reeve's description and figure : the species has 

 not been recognized by collectors. I am strongly inclined to 

 consider it a worn specimen or a variety of C. monilifera, in 

 which the revolving riblets have disappeared or failed to be 

 developed. 



C. FULGIDA, Reeve. PL 53, fig. 2. 



Shell rather elongated, transparent white, shining, subangulated 

 on the periphery : painted longitudinally with faint waved orange- 

 brown streaks ; lips slightly denticulated within. 

 Length, 7-8 mill, 



Port Lincoln, Australia (Cuming Coll.). 



Noumea, New Caledonia (Brazier). 



C. LACTEA, Duclos. PL 53, figs. 3, 4. 



Shell smooth, white, striate below ; aperture dentate within. 

 Length, 19 mill. 



Indian Ocean, Seychelles Islands. 



Duclos published a figure with name, but no description : his 

 specimen was possibly denuded of its coloring. The localities 

 are supplied from Kiener's. monograph, although the shell figured 

 by Kiener is so different (fig. 4) that it may well be another 

 species. 



C. ESSINGTONENSIS, Reeve. PL 53, figs. 5, 6. 



Shell smooth, polished, with revolving grooves below; white,
