Family Naticide. 
Natica impervia, Phil. 
Natica impervia, Philippi, Archiv fiir Naturg., vol. i. p. 65 (1845). 
Hab.—Station 346, from Sponge at 56 fathoms. 
Only very dead and featureless specimens. 
Family Trichotropide. 
Trichotropis antarctica, sp. n. (Plate, fig. 7). 
T. testa parva, imperforata, fragili, breviter fusiformi, sordidé alba, anfractibus 6, quorum apicales tres 
detriti, subleeves, ceteris tenuiter et arcté decussatis, interstitiis quadratulis, ultimo cteros exsuperante, 
apertura ovata, labro multum expanso, inflato, margine columellari paullum excavato. 
Alt. 5°75, diam. (oris) 3°50 mm. 
Hab.—Trawl, Burdwood Bank, at 56 fathoms. Station 346. 
A very interesting form, and we deem it worthy of description, albeit the only 
specimen is imperfect, and the outer lip infested with growth of a Bryozoon. It seems 
adult, and is comparable with no other member of the genus known to us. It is much 
smaller in all its parts than T. «nornata, Hutton, from New Zealand. ‘There is no sign 
of umbilication, and the epidermis is not present, being completely worn off.
