1012 A REVISION OF THE AUSTRALIAN ISOPODA, 



the head : the outer were twice as long as the inner pair. In a 

 second specimen the inner pair are as long as the head, composed 

 of five segments of nearly equal size — the foui'th the longest, the 

 fifth shorter, ornamented at the extremity with numerous fine 

 hairs ; the outer are about half the same length as the inner ; 

 their flagellum very stout, a little longer than the peduncle, of 

 eight articuli. In a third specimen the outer antennae are nearly 

 as long as the head and first two segments, the flagellum having 

 thirteen joints ; the inner pair are broken off. 



I may add to the description originally given that the propodos 

 of the first pair of peripods is ornamented on its palmar border 

 with a few fine hairs : the dactyli likewise have a few very short 

 hairs along their inner border. The "palm" of the second and 

 third pereiopods is provided with short straight spines, and there 

 are similar spines on the carpus and propus of the following pairs.

I give here an outline of the antennte of this species. In the 

 flagellum of the outer pair there are seven distinct segments, the 

 first large with indications of subdivision into two ; the last two 

 very small.

A very distinct variety of this species, or perhaps a distinct 

 species, has been described by Miers (I.e.) as found at Dundas 

 Straits by Dr. Coppinger.

 The body is long and narrow ; the first segment is longer than 

 the head and projects like a hump behind ; the segments of the
