12 . Phyloqeny and Classification. 
Haller (136) gives a phylogenetic tree for the principal divisions of 
Mollusca. 
Grobben (132) treats of the phylogeny of the Mollusca and classifies 
as under : — 
Type— Mollusca. 
I. Subtype Amphineura. 
II. „ Conchifera. 
I. Class Prorhipidoglossomorpha. 
1. Subcl. Gasteropoda. 
2. „ Solenoconchce. 
3. ,, Lamellibranchiata, 
II. Class Cephalopoda. 
Schwarz (335) proposes to divide Cephalopoda into Endocochlia : — 
Belemnitidce , Sepiadoz, Teuthidai, and Spirjilidce ; and Ectocochlia : — CL 
Nautiloidea, Ammonoidea , and Octopoda.
