A fully illustrated account of this southern species is given in the first reference, 

 and a brief diagnosis of the species will be found in the second. 



Colour. — The umbrella is colourless, but the general tint of the creature is 

 pale brown, due to the colour of the endodermal canals and of the female gonads, 

 which are orange-brown. (According to von Lendenfeld, the male gonads are rose- 

 coloured, but I have no note as to any of the specimens seen by us being thus tinted.) 

 The oral lobes or arms are " white, with purple margin, or purple throughout." 



Dimensians. — Only moderate-sized individuals were captured, measuring about 

 6 in. in diameter, but I have seen specimens thrown ashore on the beaches near 

 Dunedin which attain a diameter of 15 in., or 375 mm. 



The exumbrella is covered with " nettle-warts," which are not limited to the 

 centre, as von Lendenfeld states. 



The margin of the umbrella ic notched so as to form 16 rounded lobes, in 8 of 

 which notches the tentaculocysts are situated. 



The long delicate tentacles in this genus are arranged in 8 groups, at some 

 distance within the margin of the umbrella ; there are about 24 tentacles in each 

 group, arising in 3 or 4 rows from a crescentic or semicircular area. 



Locality. — Auckland Island : Norman's Inlet (W. B. B.). 



Distribution. — New Zealand, Australia (Port Jackson).

Although my specimens do not agree in all points with the diagnosis of this 

 species given by von Lendenfeld, and in several respects resemble A. aurita, Lamarck, 

 yet, as the latter species appears to be confined to the Atlantic and European seas, 

 and as A. coerulea is the only species to which the present specimens bear any close 

 resemblance, I prefer, in the absence of more certain data, to refer them to this Aus- 

 tralian species. At the same time, the difference between the two species appears 

 to be very slight, though I observe that in a recent communication to the Proc. 

 Zool. Soc. (1909, p. 78), Mr. Goodey makes mention of having examined A. coerulea, 

 80 that I presume the species is valid. But a careful comparison of a good series 

 of specimens may perhaps necessitate their union. 



I have been able to compare our jellyfish with specimens of A. aurita obtained 

 from Plymouth, England, some years ago. They are not now in such a good state
