History. — It is to be regretted that Mr. J. W. Salter, whose 

 masterly descriptions of British Trilobites have been of such 

 assistance to us, did not live to describe the New South Wales 

 species submitted to him by the Rev. W. B. Clarke; it is more 

 than possible that some of his MS. names would fit several of the 

 trilobites described by us. 



Calymene was first reported as an Australian fossil by Dr. A. 

 R. C. Selwyn, from Simmonds' Bridge, Upper Yarra, and Duck 

 Creek, near Melbourne;* and was followed by Salter, who named 

 one of Clarke's specimens C. Macleayi, from somewhere in the 

 " Southern Districts."! It would appear that one or more of the 

 Victorian specimens was named C. tuberculata by McCoy, | but, 

 as no author's name is attached, it is impossible to say whether 

 this was a MS. name of McCoy's, or intended for C. tuberculosa 

 Salter, a well known species of the Wenlock Series. Next in 

 order, we again meet with our friend De Koninck, who reported
