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. 

 l\\ mil.; anfr. 4.

This is the var. B. of M. Brot [pi. 32, fig. lA.], which, how- 

 ever, judging from the locality, I consider to be the typical 

 form.

These latter agree exactly with the Ceylon specimens. They are 

 the No. 3 [" M. t^iherculata"'], 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." Two 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.
