Certainly distinct, I think, from M. mauiensis; even more 
closely resembling M. lateritia. These specimens agree fairly 
with the above-quoted figure, only the last whorl is more con- 
vexly tumid and the aperture more dilated, Long. 22, diam.

2 Halmaheira ; ex Mr. Landauer. 
This is the var. B. of M. Brot, [pl. 32, fig. 1A.], which, how- 
ever, judging from the locality, I consider to be the typical 
orm.

These latter agree exactly with the Ceylon specimens. They are 
the No. 3 [“ M. tuberculata”], var. D. of Theobald’s Catalogue, 
page 40. I should much like to see the locality confirmed. I 
fear there may have been some confusion.

These are doubtless part of the preceding donation, which it 
was not considered necessary to “mount.” ‘T'wo are of a small, 
dwarf race, and three are not decollate, in this state resembling 
very closely the Halmaheira specimens.

These include two or three varieties ; one especially with very 
ventricose last whorl and finer, more close-set sculpture; another 
is without any longitudinal, decussating sculpture, and is of a 
uniform dull violet colour.
