 sixth ridge in one specimen conspicuously, in the other verj- slightly 

 interrupted in median line. Arrangement as in Pt. dasipnalhis.

 have been living almost seven years in continementj, is similar in 

 colour to the specimen described above. In both of these females 

 the mantle is mixed creamy-white and brownish, not defined by a 

 straight line behind, but passing rather irregularly into the dark 

 brownish colour of the back. In the second cotype, a male (al. ; 

 almost seven years in confinement}, the whole of the mantle, sides
