 Long. 30, mnj. lot. 12 millim. 

 Hab. South Sea ? 



A fine handsome species, one of the largest of the genus, and 

 entirely different from any hitherto known or described. I found two 

 perfect specimens of this species in the collection of the late Mr. D. 

 Filby of Hamburg with a label "South Sea," but even this indefinite 

 locality is not to be relied on. The largest of the two, which I 

 have taken for the type, forms part of the gift made by Mrs. Filby to 

 the Hamburg Museum. The second specimen is about 27 milHm. 

 in length, and of the same form, proportions, colour, and markings 

 as the type.
