ECHINODEEMATA. 



In 1886 the " Catalogue of the Blastoidea of the British 

 Museum," by E. Etheridge, jun., and P. H. Carpenter, was 

 published.^ In it, is figured and described Actinocrimis 

 Bennei, a Carboniferous species named by Pi. Etheridge in 

 1876, after the finder, our late fellow, Mr James Bennie.^ 

 This is one of many discoveries by which his name is linked 

 with palaeontology. 



One of the most interesting discoveries of Echinoderm 

 remains recorded from the Palaeozoic rocks during the period 

 under consideration is that of plates, wheels, and anchors of 

 holothurideans from the Carboniferous Limestone rocks of 

 Scotland, by the late Mr Bennie, described by K. Etheridge, 

 jun. Mr Etheridge provisionally ascribes the plates to 

 species of the genus Chirodota and Achistrum. This is the 

 first record of remains of this group having been obtained 

 from Palaeozoic strata.^ 



ANNELIDA. 



In a series of papers published in the Geological Magazine 

 for 1880, E. Etheridge, jun., adds greatly to our knowledge 

 of Scottish Carboniferous tubicolar annelides.^ For this pur- 

 pose he avails himself of materials from the Carboniferous 

 rocks of Scotland, especially from the Calciferous Sandstone 

 and the Carboniferous Limestone groups of Fife and the 

 Lothians, from the collections of the Geological Survey, the 

 late Mr C. W. Peach, and the late Mr James Bennie. 



He reviews the genus Spirorhis, and breaks it up into two 

 sets, Spirorbis and Microconchus. Of nine species from Scot- 

 land, three are new. He also reviews the genus Serpulites, 

 Macleay, and describes three species, two of which are new.
