76 COLLECTIONS FROM MELANESIA. 



Messrs. Adams described these spots as being " round '' in the 

 specimen they examined ; in those before me they are rather 

 angular, being the zigzag turn of the longitudinal lines. A third 

 variety has a pale band round the middle of the last volution which 

 falls at the lower part of the upper ones, the upper portion being 

 pinkish or closely lineolated with pink. The lower half of the body- 

 whorl has a broad pinkish band beneath the centralwhite one, which 

 is succeeded by a narrower plain zone, which in turn is followed by 

 another fine pink one. 



A fourth form, with the exception of the upper part of the spire 

 and the umbilical region, is of a uniform greyish violet. 



The largest specimen is twelve millim. long, and consists of 

 eight whorls. The spiral suleation and ridging is much more deve- 

 loped in some specimens than others. In the largest there is quite 

 a strong keel near the base of the upper whorls, which gradually 

 diminishes upon the last. In others the whorls are almost smooth, 

 with the exception of the base of the last, which invariably presents 

 a few sulci circumscribing the narrow umbilicus. The presence of 

 the latter peculiarity and the very slight difference in the columella 

 do not appear to me sufficient characters to separate this species 

 generically from Bankivia. The general form of the shell, its 

 texture, and the style and variation of painting are the same. Other 

 points of resemblance are the thickening or margination of %e whorls 

 at the suture, the striation or suleation of the base of the last, the 

 non-pearly aperture, and finally their geographical distribution. 



A second species (?) of the section Leiopyrga has been briefly 

 described by A. Adams (P. Z. S. 1863, p. 507) from Port Essington, 

 under the name of L. cmgulata. It presents similar variations in 

 colouring as in the other species, and, indeed, might even be con- 

 sidered another form of it with the carinations and lirse more pro- 

 nounced.
