CAMITIA. 4H.> 



The systematic position of this group is not known to me. Fischer 

 places it under Clanculiui as a subgenus. 



C. ROTELLiNA Goulcl. PI. 63, figs. 18, 19. 



Shell covered-perforate, discoidal, depressed, smooth, shining ; 

 whorls 6, under a leris veiy minutely, obliquely striate ; the earliest 

 whitish, spirally obsoletely sulcate, the remainder pale flesh-colored, 

 ornamented with a subsutural linear zone and oblique brown spots ; 

 last whorl dilated, obtuse in the middle, spirally trilineate (one line 

 above, two at periphery), somewhat convex beneath, with two zones 

 of brown spots ; aperture transverse, scarcely sulcate within ; col- 

 umella nearly horizontal, twisted above, truncate beneath, columellar 

 callus forming a coating to the extremely oblique umbilicus.

I have not seen specimens of Camitia. Fisher's remarks under 

 this species are as follows : 



The shell above described is incontestably a Camitia, and verv 

 probably the C. pulcherrima figured by Adams and Chenu, but I 

 have not been able to find the work in which C. pulcherrima was de- 

 scribed by Gray in 1840. Camitia is a Clanculus very much de- 

 pressed, like Rotella, and with a smooth shell like Chrysostoma, 

 Photinula, etc. The right margin of the lip has the character of 

 that of Rotella. 



A copy of Adams' figure oi pulcherrima is given on pi. 57, fig. 11. 



C. GRAYi A. Adams. 



Shell orbicular, convex-conoidal, very smooth, fiesh-colored, or- 

 namented with subquadrate rufous spots at the suture ; peripherv 

 whitish, with two series of reddish-brown transverse spots ; base 

 whitish. (Ad. in P. Z. S. 1854, p. 42.) 



Hahibd unknown.
