verse ridge. Tliere is a small tubercle over the eye, and another 

 on the occiput, besides several minute ones scattered over the 

 upper part of the head. Length of the head and body 2-50 to 

 2*75 in that of the tail. The rings of the body and tail have 

 each above and below on either side a minute tubercle at their 

 hinder ends, There is a row of minute tentacles on the mid-line 

 of the body, and there are others on the dorsal ridges of the tail 

 and on the sides of the egg-pouch. 



Dorsal, pectoral, and caudal tins well developed, and in the 

 female specimens there is also a minute anal. Dorsal placed 

 opposite to the vent, its base covering three segments, and the 

 rays equal to about three-fourths the depth of the body. Egg 

 pouch of the males equal to the trunk in length. 



Colours of preserved examples various, but generally with 

 broad darker cross bands on the sides, and a chain-like pattern 

 of lighter markings on the back. In life they are most brilliant. 

 Some are bright blue along the sides, with broad dark-brown 

 vertical bars, which are more or less in pairs. Back either pure 

 white or variegated with lighter and darker chain-like circles. 

 Opercles scarlet. Others have a similar pattern, but the blue 

 ground is more or less broken by yellow and pink areas. 



Flab. — Seven specimens taken in rock-pools on the coast near 

 Sydney. They appear to differ from Gunther's description only 

 in having fourteen instead of sixteen body-rings.
