Foasil Vohites. 199 



but if so. his treutiiit'iit of it is of such an obscure and uncertain 

 character, that it wouhl l)e the merest guesswork to place it. In 

 1888 Mr. Johnston gave a figure in the Geology of Tasmania 

 ■which did not represent V. allporti, though purporting to do so. 

 In the same year Professor Tate failed to recognise V. allporti^ 

 Johnston. 



The original descriptidu of V. allporti, is. " Shell large, ovately 

 fusiform, of six regularly increasing whorls, besides a small pullus, 

 Avhich is too imperfect in the various specimens for description; 

 spire acute; apical angle 45 deg., slightly concave in outline; 

 whorls slightly convex, and only ornamented with line longitudinal 

 lines of growth; aperture I'ather narrow, elliptical; lip not ex- 

 panded into a wing, simple; columella curved, with four distinct 

 slender o])lique plaits; length, when perfect, about eight inches, or 

 20(» mil., breadth 65 mil., proportional length of body-Avhorl about 

 eo-KKlths of penultimate 9-lOOths.'" 



This species is referred to as the " largest Volute in Table Cape 

 Beds, and has much the general appearance of V. macroptera 

 (McCoy) in its young state, but has a smaller pullus, and differs; 

 materially in the size, number of whorls, and the absence of an. 

 expanded wing." 



This description does not agree with V . /uilli, and might confuse 

 two or three species, and in view of the confusion already existing 

 I would recommend the removal of V. allporti from our lists.

 specimen so labelled that I have examined in that Museum is a 

 young example of T'. /inlli. Recently I received a genuine young 

 example of this species from Mr. R. X. Atkinson, and this is the 

 first occasion on whicli a specimen has come under my notice. The 

 Tal)le Cape specimen is a slight variant on McCoy's species, as it
