The association oi Siphonotreta Scotica, Dav., has thus been given 

 both as regards its Canadian and European contemporaries. There are 

 are a number of other forms occurring throughout the section at the 

 Eapids, in Gloucester, not mentioned which would swell the list con- 

 siderably, but subsequent researches will help in ascertaining their 

 precise affinities and lead to other forms being found. 



There remains much work, however, to be done in ascertaining 

 the internal characters of this pretty little spinose brachiopod which in 

 Scotland and Canada used to flourish in the old Cambro-SUurian 

 Seas. 



Should any member of the Club find any specimen or S:pecimens 

 of Sip/ionoireta Scotica or of its Canadian variety which would throw 

 additional light and show the muscular and other impressions of the 

 interior of this shell belonging to the division of the Tretenterata, he 

 or she would be conferring a favour to Science by contributing the 

 same in the Club's Transactions or elsewhere.
