This species is a very variable one — indeed, it is questionable whether it should not 

 be broken up into at least three different specific types. The specific character is, 

 of course, indicated by its name — a typical pink colour. Secondary to this comes an 

 elevated trochoid spire and the presence of arched secondary apertures on the 

 superior surface of the shell. Both or either of these features may be suppressed 

 or absent in any series of specimens, the secondary apertures being the least constant 

 and apparently confined to large tropical specimens. At Kerimba the species occurs 

 nearly everywhere, and is in nearly all cases represented by a type in which the 

 dominant pink colour is well marked and constant, but the secondary apertures are 

 absent, and the trochoid spire is comparatively inconspicuous. The specimens are 

 thus mainly separable from G. lulloides by their pink coloration only. The only 

 typical specimens presenting the elevated spire and the secondary apertures were noted 

 at Stn. 11, and, curiously enough, the majority were almost devoid of coloration, but 

 a few typically red individuals were found. At Stn. 2 a few individuals were found 

 of the minute type so abundant in Northern Seas in which a comparatively high spire 

 is present, but no coloration. Such individuals are to be found in muddy littoral 

 deposits all over the world.

Fairly generally distributed, but only a few specimens at each Stn., and these 

 poorly developed, except at Stns. 10, 11, and 12, wliere the specimens are larger and 

 quite typical.
