1903.] MOLLUSCA OF THE “‘ SKEAT EXPEDITION.” 197 
A single specimen “from rotten wood.” Recalling in shape 
A. perakensis Smith, the present species is larger and stouter, and 
the tube slants obliquely upwards instead of descending ; as com- 
pared with 2. lorraini Pfr., which also has an ascending tube, the 
form is not so cylindrical, the whorls are flatter, and the size is 
much greater. 
RHAPHAULUS PERAKENSIS Smith, var. JALORENSIS, n. var. 
(Plate XX. figs. 9, 10.) 
Shell very similar to 2. perakensis Smith, but a little thinner 
and paler in colour, and the tube is bent along the outer lip, being 
attached to the lip, and not diverted behind it as in typical 
R. perakensis. The tube is broad and short. This form may prove 
to be a distinct species, but bearing in mind the great variation 
shown by Col. Godwin- Austen (Moll. India, vol. i. p. 202, pl. xlvii.) 
to exist in A. blanfordi Benson, and also considering how little we 
know of the group, most forms having been described from very few 
specimens, I have thought it wiser to give only a varietal name.

Agrees well with Stoliezka’s figure 12, but his figure 11 looks as 
if it might belong to a different species.
