WiLCKENS.— Lahillia and other Fossils from the Upper Senonian. 541 
In 1910 Lahillia luisa was cde from the Antarctic Upper 
Senonian (11), and L. larseni Sha & Newt. sp. from the Antarctic 
Tuar (12). Woods (13) in 1917 described a Lahillia from the Upper 
Senonian of New Zealand under the name Mactra? This determination 
was rectified by me in 1920 (14). 
In 1907 v. Ihering (15) wrote, “The genus Lahillia, which is well 
developed in the Upper Cretaceous and Palaeogene faunas of Patagonia cet: 
Chile, has not been found in New Zealand," and “ Lahillia seems not to 
reached New Zealand." One sees that his cautious manner of puting 
was justifiable.

Three крона casts. Only to one of these are rem some small 
pu of the shell. 
e normal sein cast of Protodolium possesses smooth whorls. Such 
ана internal casts as occur at the locality 592 (see above, Lahillia /) 
may have been formed in the following manner: The shell was equally 
dissolved on the whole surface, so that finally the ornamentation was 
transferred to the cast when the innermost layers of the shell were dissolved.
