SMITH : ON MOLLUSCA FROM TIKRRA DEL FUEOO. 339 



Long. 10-25, diam. 6 mm.; apertura 6 mm. longa, 5 lata. 

 Hah. — Admiralty Sound. 



Apparently very like S. Lehruni, Mabille,' but without the san- 

 guineous apex, and rather more coarsely sculptured. 



20. Amphidoxa (Stephanoda) lyrata (Gould). 



Hab.— Rio McClelland. 



Two specimens apparently belonging to this species, which was 

 collected originally by Couthony at Orange Harbour on the eastern 

 side of Hoste Island, one of the detached islands south of the main 

 island. 



21. Payenia(?) sp. 



A single immature shell from llio McClelland may belong to this 

 genus, created by Mabille & Eochebrune ^ f or the Helix saxatilis of 

 Gould from Orange Harbour. 



22. Chilina Fuegiensis, n.sp. Fig. vii. 



Testa angusta, elongata, tenuis, sub tegmine terreno nigro olivacea. 

 lineis rufis longitudinalibus undulatis picta, lineis incrementi tenuibus 

 striata, striisque spiralibus minutis obscure sculpta ; anfractus 5-6 

 valde convexi, ultimus elongatus, antice oblique descendens ; apertura 

 elongata, inverse auriformis, intus plus minus purpureo tincta et 

 strigata ; columella alba, plica tenui obliqua supra instructa, antice 

 reflexa, superne callo tenui labro juncta. 



Long. 24, diam. 10 mm. ; apertura 13'5mm. longa, 5*5 lata. 



Hah. — Rio Marazzi, Useless Bay. 



This species, the only one recorded from Tierra del Fuego, is re- 

 markable on account of its slender form. All the specimens were 

 coated with a black earthy deposit, which can easily be removed with 

 a little diluted hydrochloric acid. Some examples are shorter than 

 others, on account of the spire being less produced. In these specimens 

 the mouth is consequently longer in proportion to the whole length of 

 the shell. The following are the dimensions of such a specimen : length, 

 19 mm. ; length of aperture, 12 mm.
