A1 with the 8th-9th and 24th-25th segments fused; it reaches as far as the line separating the 3rd and 4th thoracic somites, which is considerably shorter than the condition described by Rose (1942, fig.16). The P5, although in agreement with Rose's and Giesbrecht's notes, has the terminal segment almost completely divided into 2 smaller segments, so that the foot appears to be 3-segmented.
