had a reason for endeavouring to supply the latter. However, as this is not the 
case with the critical lists of the Brachiopoda, Avhich arc probably at the present 
time in preparation, I have not the same ohjeet in view as I had before. Besides, we 
may fairly expeet that Prof. Pictet’s aecounts, Avith the larger materials at his 
disposal, will he far more eomplete than anything I could supply. 
In this AA'ay my Avorlc will he limited to giving detailed descriptions and figures 
of those species Avliich occur in oiu South Indian cretaceous deposits, and I shall 
only briefly preface these descriptions by a short statement of the organisation of 
tlie class, and of the families and genera to Avhich the Indian speeies are referable. 
A brief summary of the geological results Avill be given in a separate article at 
the end of this paper.
