CRUSTACEA DECAPODA— 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 LXIX, ii, 3, p. 437, 1900) states that the exognath of 

 the third maxilliped of Plagusia has no flagellum. In the present species a small but 

 distinct flagellum is present.
