The typical form has only a few scattered brown stripes, ornamented by white dots; 
but the var. heynemanni is very richly painted with broad black stripes on a ground 
which is whitish on the upper whorls and becomes more and more ochraceous-yellow 
towards the lower half of the last whorl. The stripes often include small pure white 
round spots, or are jagged on the side towards the aperture, sometimes projecting two 
or three branches in that direction, which, if they are repeated in the following stripes, 
may form three broad interrupted spiral bands. All the stripes break off at the same 
distance from the umbilicus. Inside the aperture the black stripes are quite as con- 
spicuous as on the outside. 
In Dr. Pfeiffer’s monograph °, Bulimus heynemanni, Pfr., and B. inglorius, Reeve, 
are somewhat widely separated, the former in 4 49, “ subperforati vel obtecte perforati,” 
and the latter in § 54, “perforati vel umbilicati.” The umbilicus is always minute, 
but in some specimens cleft-like, oblong; in others from the same locality, similar in 
all other respects, it is nearly circular. Strebel’ has already suggested the identity of 
B. heynemanni and B. inglorius, and after having examined a considerable number of 
specimens collected by Herr Hége, I quite agree with him.
