oppressed posteriorly, eared on the upper external angle. When 

 viewed in profile a second lip, similar to the first, is discovered 

 immediately behind the aperture proper. Within the aperture 

 is bevelled and contracted in a funnel, a small tubercle is seated 

 •deep within the aperture on the right side. Length H, breadth

H a b. — Oubatche, New Caledonia. 



Type to be presented to the Australian Museum. 



Oubatche is a station on the north-east coast of New Caledonia 

 about 20" 28" south latitude.* I procured this shell on the slopes 

 of Mount Ignambi, about four miles distant from the house of 

 my kind hosts, Messrs. A. 0. and J. Henry, where the road to 

 Ouaco enters the first piece of jungle. Among fallen leaves and 

 dead sticks on stony ground I found the new Diplommatina in 

 tolerable abundance, AVith the novelty was another and a larger 

 Diplommatina 2^ mm. long. I am inclined to consider it D. 

 perroquiniana, but the account of D. mojitrouzieri answers to it 

 almost as well. In doubt whether it be a 

 distinct species or a link between these two, 

 I refrain from describing it as new, but 

 content myself with presenting a drawing 

 (fig. 11) of this larger Oubatche species. 



From New Caledonia there are alread}' 

 known three representatives of this genus, 

 all found l>y one diligent and acute collector 

 in the southern end of the island. They are 

 D. mariei, Crosse, (Journ. de Conchyl. xv. 

 1867, p. 179, PL XVI. f. 6) ; D. perroqui- 

 niana, Crosse [op. cit. xxi. 1873, p. 144, PI. i. 

 f. 6); and D. montrouzieri, Crosse {op. cit. Fig. 11. 



xxii. 1874, p. 394, PI. xii. f. 8). Besides its distant habitat, 

 D. ohesa is easily separated from these as well as from most known 

 species by its minute size and toothed aperture. This feature is 

 common to such Diplommatina as the Papuan D. symmetrica and
