Chilton. — On N.Z. Ampliipoda and Isopoda. 259 



not repeated the references already given in the Critical List. 

 In the case of some species I have given only short diagnoses, 

 hoping to supplement these at some future time with fuller 

 descriptions and figures. In other cases I have mentioned 

 species merely to state what questions require solution.

This species was first briefly described by Mr. Thomson 

 in the Neio Zealand Joiirnal of Science, vol. ii., p. 577. 

 This description was reproduced in the Proceedings of the 

 Zoological Society for the 19th January, 1886 (p. 4), by 

 Mr. Stebbing, who afterwards fully described and figured the 

 male in the Transactions of the Zoological Society, and Mr. 

 Thomson supplemented this by a description of the female in 

 the Transactions of the New Zealand Institute, vol. xxi., 

 p. 260. 



The species was originally taken at Purakanui, near 

 Dunedin. I afterwards took it on the Ninety-mile Beach, a 

 few miles north of Timaru ; and in Mr. Thomson's collection 

 there is one specimen from Waipapapa Point, collected by Mr. 

 J. F. Erecson. The form of the second gnathopod of the 

 male varies very considerably, apparently according to the 

 growth of the animal, and its development needs working out 

 in this as in many other species of the Orchestidae.

I have for some years had specimens from Lyttelton Har- 

 bour that I now refer without much doubt to this species, 

 which is described by Stebbing from two female specimens 

 taken off Cape Agulhas, South Africa. My female specimens 

 agree very closely with his description ; the males, whifth he 

 had not seen, differ in having the peduncles of the antennas 

 longer, and especially in the second gnathopoda, which have 

 the propodos very large — about as large as all the rest of the 

 limb ; the anterior edge is convex ; the posterior edge is straight, 

 and produced distally into a sharp tooth, at the base of which 

 is a small projection on the inferior margin. The dactylos is 

 fully as long as the proj)odos, and has a slight enlargement on 

 the inner margin, at some distance from the base; its inner 

 margin, and the whole of the posterior margin of the propodos.
