selected for illustration happens to be distorted in sucli a manner as 

 to make the transverse striiTc appear to be directed forwards, biit in 

 another individual they certainly incline backwards, and this is probably 

 their normal arrangement. 



AcT.'EON, (Sp. undi.) 



In bi caking up some pieces of shale from either Maud or Lina Island, six 

 specimens of a small gastero)pt)d were discovered, wliieh ])erhaps belong- 

 to this genus. The test is not preserved in any of Ihein, so that their 

 distinctive features are unknown, and it is also doubtful whether there 

 are two species, or only two different stages of groM'th of the same shell. 

 Four of these are composed of three whorls, of which the last one is at 

 least three times as high as the spire. The general shape is ovate ; the 

 bod}'- whorl is intlated and evenly rounded above ; the sutures are not 

 cliaunelled. In the two remaining specimens the spire is broken, but the 

 body whorl is narrowly C3'lindrical and much elongated, it is distinctly 

 shouldered and angular above, and the sutures (of the cast) are deeply 

 grooved. The whole of the specimens have one feature in common; and 

 that is that the last volution of the casts is encircled or im])ressed by 

 revolving grooves. 



No traces of a thickened lip can be detected, and these little shells are 

 therefore placed in Montfort's genus J.(;f^TOn (of which Tornatella, Jjamavck, 

 is a synonym) though they may possibly prove to be Cinalim. 



AcT^ONiNA, (Sp. undt.) 



A narrowl}' cylindrical and short-spired shell which very closely re- 

 sembles some of the European Oolitic Actasoninse, is abundant in pieces 

 of shale from the islands in Skidegate Channel. The specimens occur 

 as mere casts, which have been subjected to almost ever}' variety of 

 compression and distortion. In an average example, about an inch long 

 the body whorl occupies nearly eleven-twelfths of the entire length. 

 It is bluntly angular above, and faintlj' striated longitudinally. In some 

 specimens the apex of the spire is obtuse, in others it is acute. The um- 

 bilicus is entirely closed, and no traces of any plaits at the base of the 

 columella could be detected, though the latter circumstance may be 

 attributable to the inqjerfect state of preservation of the fossils. They 

 are indeed in such bad condition that their generic position even is 

 uncertain,
