THE SHELL GAME: WHO'S UNDER WHAT? MORPHOLOGICAL EVOLUTION AND TRAJECTORIES THROUGH MORPHOSPACE EXEMPLIFIED WITH SPECIES OF LAMBIS Doctor of Philosophy 1997 J. R. Stone Graduate Department of Zoology University of Toronto Morphological space provides a means of analysing the physical forms of organisms. Mathematical modeling allows patterns generated by biologicai processes to be analysed. And cladistic methodology permits the formulation of phylogenetic hypotheses conceming groups of organisms… 

Mapping cladograms into morphospaces

TLDR
A method for synthesizing phylogenetic results that are interpreted from cladistic analyses with phenetic results from morphological space analyses is presented here; in particular, points that represent forms typifying taxa in morphospace are assigned as terminal nodes for appropriate cladograms that are mapped into morphospaces by positioning nonterminal nodes and orienting internodes according to a geometric algorithm.

Terestrombus and Tridentarius, new genera of Indo- Pacific Strombidae (Gastropoda), with comments on included taxa and on shell characters in Strombidae

TLDR
A previously unrecognized character, nature of edge of outer lip, is discussed, as a potentially informative feature from strombid phylogeny, which has evolved multiple times in Stromboidea, including Tridentarius.
