from perversus. The deep yellow colour inside aperture is 

 not always present, some specimens I have from Busuanga 

 Island being quite white throughout.

A very unsatisfactory variety : the figure in ' Ost-Asien ' is 

 probably badly coloured, and it is difficult to say to which 

 variety oi perversus it belongs ; the figure referred to in F«5r. 

 is a typical perversus ; but neither agree with the H. dextra 

 (Chem.ix. figs. 1210, 1211), which does agree with a specimen 

 of mine identified by Prof, von Martens as being his var. 

 aurea. This shell is a rather small globose form oi perversus, 

 of a uniform golden-yellow colour.

Diflfers from perversus in having the lower part of the last 

 whorl covered with reddish-brown stripes and spots, which 

 are often interrupted by a narrow yellow spiral band. Closely 

 allied to interruptus of Miiller, but smoother.

Miiller's type, as figured in Chem. figs. 1213, 1214, is a 

 decorticated specimen, with fewer markings than in most 

 specimens. Lamarck's sultanus was founded upon specimens 

 of this variety in good condition.

This variety can generally be distinguished from the fore- 

 going by the absence of any dark colour at back of lip, its
