CRUSTACEA DECAPOD A—BORRADAILE. 
101 
The figures given by Leach and Milne-Edwards do not accurately 
represent the third maxilliped of this species. The propodite is 
articulated to the outer angle of the distal end of the ischiomeropodite, 
and does not project beyond its inner edge. In this, as in all other 
respects, the New Zealand specimens agree with British examples. 
Two female specimens from D’Urville Island, and one from Nelson, 
New Zealand, all taken in mussels.

Alcock (J. As. Soc. Bengal UNIX, ii, 3, p. 437, 1900) states that the exognatli of 
the third maxilliped of Plagusia has no flagellum. In the present species a small but 
distinct flagellum is present.
