You spelled it wrong...
According to the Garstang Hypothesis, development of sexual maturity in a non-metamorphosing lineage of tunicates might provide the immediate proto-chordate ancestors of more typical chordates such as Amphioxus (Subphylum Cephalochordata), or even of early Vertebrata (Ostracoderms) as shown here. Development of sexual maturity in a larval form is an example of Progenesis (Garstang called the process Neoteny, which today is used for a different but related differnetial growth phenomenon).
