200 1MBRICARIA. 



I. PUNCTATA, Swainson. PL 58, figs. 6*79-681. 



Yellowish white, clouded with a darker shade, apex black ; 

 body-whorl encircled. with engraved, sometimes minutely punc- 

 tured lines. 



Length, -5-'8 inch. 



Society Islands. 



With this species must be united M. conovula, Quoy, partly 

 (fig. 681), and M. ossea, Reeve, a name given because Swainson 

 had previously given that of punctata to a Mitra; M. truncata, 

 Kiener (fig. 680), a poorly figured shell, may also be placed here 

 for the present. 



I. LINEATA, Swainson. PI. 58, fig. 678. 



Yellowish, smooth, with revolving chestnut hair-like lines. 



Length, 1 inch. 



Inhabits the South Seas. 



This species has not been recognized by the monographers. 

 It is described as smooth, yet I think it is merely a large punctata, 

 which it much resembles in the spire and upper part of aperture. 



I. VIRGO, Swainson. PI. 58, fig. 683. 



Yellowish white, apex and base tipped with black-violet, spire 

 much depressed, mucronate, upper portion of body r whorl swollen. 



Length, '6 inch. 



Polynesia ? sand at low water. 



Although so bulbous, I cannot help thinking that this will 

 prove to be an extreme variation of /. punctata. 



I. YANIKORENSIS, Quoy. PI. 58, figs. 684, 682. 



Encircled by closely punctured striae ; ashy, or reddish gray, 

 whitish towards top of body-whorl and on the spire, ornamented 

 with numerous minute white spots and streaks, edged with 

 chestnut ; aperture chestnut within. Length, '65-'9 inch. 



Philippines ; Polynesia, in sandy mud at low water. 



I find no good reason for the separation from this species of 

 I. DeburgMx, Sowb. (fig. 682), recently described from Taheiti.
