45. Amblyops australis n. sp. 



Frontal margin of the carapax evenly arched. Ocular plates 

 divided by a longitudinal keel, forming a slight projection anteriorly, 

 external part somewhat hollowed. Antennular peduncle rather short 

 and robust. Antennal scale by about half its length surpassiDg the 

 antennular peduncle. rather narrow, lanceolate, the spine on the 

 outer margin placed close to the base of the scale. Posterior part 

 of body wanting in the specimen examined. Length of anterior

Hab. Off entrance to Port Philip, Bass Strait (Stat 161), 38 

 fms. Only the anterior division of the body of an adult male. 



Remarks. Although only represented by a fragment, this form 

 may be satisfactorily distinguished from either of the two other 

 species by the rather different shape of the ocular plates and of 

 the antennal scales.
