15 . TorHatellwa wconspicua, Brazier, 1872 . 
Description. Brazier, P.Z.S., 1872, p. 619; Pfeiffer, Mon. Hel. 
Viv., Vol. viii., p. 319 ; Aust. Mus. Mem. 2, p. 27.

published.

17. I). capillacea, Pfeifer , 1854. 
(Plate xxi., fig. 2.) 
Descriptions. Pfr., P.Z.S., 1854, p. 303 ; Pfr., Mon. Pneu. Viv., 
Vol. ii., p. 12.; Brazier, Aust. Mus. Mem. 2, p. 27. 
Type. British Museum. 
Of the smaller Diplommatina I have three lots before me, No. 
1, collected by Mr. Masters on Lord Howe, from which the 
example figured was selected ; No. 2, collected by the expedition 
on Lord Howe ; No. 3, collected by the expedition on Rabbit 
Island. These range in length from 3* (No. 1) to 4i mill. (No. 2) 
in length. Some individuals are more closely costulate than 
others, sometimes the ultimate, sometimes the penultimate whorl 
is the most densely ribbed ; the coloration varies from light yellow 
to pale purple, and some specimens are considerably narrower 
than others. Though none correspond to Pfeiffer’s description of 
chordata , this instability of character inclines me to suppose that 
a larger collection from different parts of the island would supply 
links to connect that species with capillacea. Indeed the large 
form macgillivrayi may also prove but an extreme variation of 
the same type.* 
* Dr. Macdonald has figured (Ann. Mag. Nat. Hist. (4), iv. pi. 4, fig. 9) 
the radula of one of the Lord Howe Diplommatin®, which one he does 
not say.
