 upon Simon for data concerning distribution in the Old Woild. 



The dissertations on distribution have been included ))ecause a study 

 of the problems of distribution is the main excuse for a faunal list. I 

 well realize that we know far too little of the fauna of this and neighbor- 

 ing regions to attempt to draw final conclusions and I also realize that 

 even if our knowledge of the spiders were perfect it would be necessary

Nearly all of the specimens referred to in this paper came either from the grassy

 of the cliff. 



to study, in connection with their distribution, the distribution of other 

 organisms, especially those of which we have more geologic records, but 

 it seems that we have now a basis for an interesting discussion at least. 

 The new records in this list come mainly from four sources, the speci- 

 mens being in the American Museum of Xatural History: collecting in 

 Cuba in September and early October, 1913, by the author and Mr. C. W.
