_Euryapteryx valgus_ Hutton, Trans. N.Z. Inst. XXV, p. 12 (1893).
This species is at once distinguishable from all others by the
extraordinary internal expansion of the distal end of the tibio-tarsus. The
tarso-metatarsus is 8.5 inches = 216 mm. in length and the proximal width
3.5 inches = 89 mm., and does not differ much from _crassus_ except in the
great proximal width, necessary to articulate with the distal internal
expansion described above.
The type came from Enfield in New Zealand.
