to this, the youngest of the chests. And the tikis, which were 

 carved by Kohuru five generations earlier, must therefore be 

 about two hundred years old. Their condition and general 

 appearance quite bear out this assumption, to say nothing of 

 the archaic style of carving, as already described. 



Quite recently another discovery of burial-chests has been 

 made, this time to the south of Auckland, on the sandhills near 

 Raglan. I understand that they have been purchased by a 

 gentleman at Wellington for his private collection. :

Though the Callianassidce of New Zealand_*are few in numbers 

 they have been only imperfectly described, and there has been 

 some confusion as to the number of species found in New Zealand. 

 This has been mainly due to the fact that, owing to their habit 

 of burrowing in sand and mud, specimens are obtained only 

 by some fortunate accident. Through the kindness of various 

 friends I have now specimens of three species, and in this 

 paper I give descriptions of these and endeavour to clear up 

 the synonymy as much as possible. I am taking the family 

 Callianassidce as used by the Rev. T. R. R. Stebbing* to in- 

 clude, among others, the two genera Upogebia and Callianassa, 

 to which our New Zealand species have been assigned, and I 

 make no attempt to discuss the characters of the genera. Some 

 discussion of these two genera is given in Mr. Stebbing' s " South 

 African Crustacea," part i, pp. 38-46, where those who are 

 interested in the matter will find numerous references to other 

 papers. Upogebia and Gebia are two names used by Leach 

 for the same genus, the former being the earlier and therefore 

 the one to be retained, f
