The nearest ally of this species appears to be T. 2)hilij)- 

 piamus of Dunker, which is found in the Straits of Magellan, 

 at Cape Horn, and the Falkland Islands. From this species 

 it differs in having the whorls rounded above, and not flattened 

 or excavated, the penultimate is larger and more elevated, the 

 body-whorl is more inflated below the middle and not pro- 

 duced into such an elongated cauda, and the canal is shorter 

 and the aperture rather larger, the longitudinal lamellae are 

 more prominent and not nearly so numerous.

Testa imperforata, ovato-turrita, tenuis, pallide rosea, circa medium 

 anfractuum linea spirali rufa ciucta, epidermide fugaci villosa vel 

 setosa olivacea induta ; anfractus 6, convexi, superne aliquauto 

 tabulati, sutura profundiuscula discreti, ubique spiraliter et oblique 

 minute punctato-striati ; apertura subquadrato-circularis, longitu- 

 dinis totius | aequans ; columella perparum arcuata, ad basini 

 leviter patula ; labrum simplex.

5. Rissoa Kergueleni, sp. nov. 



Testa ovata, semipellucida, vitrea vel lactea, ad apicem pallide 

 rubescens, tenuis, imperforata ; anfractus 5, convexi, politi, sutura 

 augustissime marginata divisi ; apex obtusus ; apertura ovata, 

 superne acuminata, longitudinis totius T 5 ^ adaequans ; peristoma 

 continuum, leviter incrassatum et expansum.

 a narrowly margined suture, and below it there is a faint 

 depression ; the first two whorls form an obtuse apex ; and 

 the penultimate is large.
