 SPECIAL REFERENCE TO CERTAIN AUSTRALIAN 

 FORMS.

The following notes have reference chiefly to a remarkable 

 member of this family which occurs on the Queensland coast ; but 

 the opportunity has been taken to give some account at the same 

 time of two other Chloraemids which have been found by the 

 author in Port Jackson, and which have not hitherto been 

 described.* A specimen of Stylarioides monilifer was investigated 

 for comparison with the new species, and a few remarks on its 

 structure will be found here and there in the following pages. 



I. Description of Coppingeria longisetosa, n.g. et sp. 



I have seen only two specimens of this remarkable Chaetopod. 

 One was dredged in 1881 by Dr. Coppinger and myself in Port 

 Molle, Queensland (lat. 20° S.), at a depth of 15 fathoms. The 

 other was got long before by the Hon. Sir William Macleay 

 during his expedition to Torres Straits and New Guinea in the 

 11 Chevert," and was dredged off Darnley Island. I have figured 

 both of these specimens, as one is more complete in one respect 

 and the other in another ; and I find it advantageous to describe 



* The only previously known Australian species of this family appears 

 to be the Siphonostomum affine described by me in a paper published in the 

 Proceedings of this Society. The same name had, unfortunately, been 

 applied previously by Leidy to another species ; but the latter, as pointed 

 out by Grube, is probably a Stylarioides.
