In T. scripta the arrangement is the same to the eleventh peripheral, where it remains low down and crosses the upper third of the pygal. In T. hilli from the front of the bridge the sulci appear to coincide closely with the sutures until the seventh peripheral is reacht. Here the sulci descend on the peripherals, but not far, and they cross the midline on'the upper part of the pygal. In the case of the neurals preserved there are some longitudinal wrinkles on the hinder ends of the third and the fifth, just behind the sulci crossing these bones. On the costals is a.
