1 This species has been found by Mr. S. H. Saxby, in the Blue Rag of the Upper Green Sand series, at Bonchurch (Isle of 

 Wight). 



2 Erroneously spelt Egnabergensis, in p. 11. This is Numulus minor of Stobceus, 1732. 



3 Several ventral or attached valves of a Thccidiarn, considered to belong to T. Wetherelli (PI. XII, fig. 39), have been 

 collected by Messrs. Sliarpe, Wright, Morris, and myself, in the Sponge Gravel of Farringdon. They have been found ad- 

 hering to valves of Ter. depressa (Lamarck), to the Aclinopora papyracea, Manon Farringdonensis, &c. Specimens with both valves 

 are found in the Chalk of Brighton. 



4 This shell has (according to M. De Hagenow) been erroneously described and figured in this Monograph, under the name 

 of Arg. decemcostata (p. 16, and PI. Ill, figs. 1 — 13), but corrected again in p. 102. Although I do not yet consider the question 

 finally settled. 



5 Several examples of this shell have been found by Mr. Wiest, in the Chloritic bed of Chardstock, along with T. pectita ; 

 the last-named species has likewise been found by Mr. S. H. Saxby, in the Chlorilic Marl of the Isle of Wight. 



6 In 1852, only one example was known, but since that period several others have been discovered in the neighbourhood of 

 Chardstock, by Mr. Wiest. 



7 In p. 40, I proposed to established a Sub-genus Kingina for the reception of this and other similarly organised forms, 

 based upon certain modifications, in the shape and attachment of the apophysary skeleton or loop; but from its having been 

 subsequently observed that these differences were not essentially distinct from what we find in Professor King's sub-genus 

 Megerlia, I am ready to abandon my former view, as it is always incumbent to simplify the nomenclature, when it can be 

 achieved without serious effects. 



3 M. De Koninck has informed me, that this species was named Spondylus undulalus, by Geinitz, in 1839, and figured in 

 the 'Die Vers., von Kieslingswalda,' pi. vi, fig. 8, 1843. I have seen the original example, now at Liege, in M. De Koninck's 

 collection, and it is certainly the same shell as subsequently described by the name of T. capillata, by Viscount D'Archiac.
