Typical panthera as figured by Ferussac is a solid, heavy 

 shell, marbled and streaked in large pattern on a whitish 

 ground, and with the columella and parietal wall pink or 

 rose, the interior pale blue. PI. 38, fig. 31, is a copy of 

 Ferussac 's type figure. 



PL 39, fig. 32, represents a shorter specimen received from 

 Robillard as from Madagascar. This agrees essentially with 

 Pfeiffer's A. lamarckiana, described as from Madagascar; 

 but the form known to be from Mozambique is also similar, 

 and it seems likely that the solid, ventricose form is wide- 

 spread on the calcareous islets and shore. Pfeiffer, at the 

 time he described lamarckiana, supposed panthera to be a 

 form with white columellar margin. 



Brancsik has described the form from the island of Mozam- 

 bique, similar to Reeve's pi. 3, f. 12, and to my pi. 39, fig. 32, 

 as a new species, under the name A. mossambica. His types 

 measure 168 mm. long, aperture 95 mm. to 137, apert. 83 mm. 

 It is stated to differ from A. panthera by the very ventricose
