2 2 GARRETT: ON POLYNESIAN MITRID^. 



represented in Reeve's figure, and one exhibits the same color 

 and markings. The other is ornamented with numerous 

 narrow longitudinal reddish-brown stripes which are minutely 

 dotted with white. The columella has five plaits. 



I am inclined to believe the latter is the form which 

 Dillwyn describes under the name of " Valuta nubila'^ Gmel. 

 variety a, which he says has '■'■longitudinal interrupted reddish- 

 brown stripes and the pillar Jive plaited.^' 



It is very nearly related to M. versicolor Martyn, which 

 is Dillwyn's Valuta nubila variety B. 



Mr. Reeve on the authority of Mr. Cuming gives Anna, 

 Panmotu Islands as the habitat, which is probably an error. 



40. Mitra oleacea Reeve, 1. c, pi. xiv., fig. 105. 



A few examples obtained under large clumps of coral on 

 reefs at the Samoa, Viti and Society Islands. 



The spiral incised lines are occasionally obsolete on the 

 middle of the body whorl, and the color though usually 

 ohvaceous is sometimes of different shades of brown. 



41. Mitra propinqua sp. nov. 



Shell sohd, elliptically-oblong, chestnut-brown with an 

 indistinct irregular pale line on the upper third of the body 

 whorl; aperture and a few small spots near the base, whitish; 

 spire rather short, with slightly convex outUnes, suture 

 grooved; whorls 6-7, flat, last on'e large, coavex, all with 

 regular spiral incised lines which are closely punctured; 

 aperture equal to half the length of the shell; outer lip 

 crenulated and the columella with five plaits. 

 Length 28, diam. 13 mill. (Coll. Garrett). 

 Hab. Society Islands. 



This appears to be a rare species. They were taken 

 from under coral on reefs. It is somewhat similar in shape 

 to M. punctata Swain., and like that species is punctate- 

 Striate but differs in color and number of columellar plaits.
