LVTZ, LIST OF GREATER ANTILLEAN SPIDERS 119 



distribntion was concerned. In Jamaica we are troubled by the fact that 

 three species of Saitis are recorded. There are three other species in 

 South America and the genus in the broad sense is known from south- 

 western Europe, western and southern Africa, India, Malasia, Polynesia 

 and Australia. If we include the records for Prostheclina with Saitis 

 the result will be to decrease the apparent distinctness of Jamaica from 

 the other Antilles, but as it is still quite distinct this would probably be 

 the fairest course. 



We then have 30 genera credited to Jamaica of Avhich 6, or 20 per cent., 

 are not known from the other Antilles. Of these 3, or 10 per cent., are 

 •not known elsewhere in ilmerica. Theridionexus and JEpecthinuIa are 

 confined to Jamaica and Cyatholipus has been found elsewhere only in 

 South Africa. Fourteen genera (43.3 per cent.) are strictly American; 

 10, or 33.3 per cent., a;re practically cosmopolitan or cosmotropical. In 

 addition to these and Saitis and Cyatholipus, which have just been me^^L- 

 tioned, Pacliylomerus is known from Jamaica, St. Vincent, Brazil (?), 

 Venezuela to Maryland, the Mediterranean region and Japan. Isclmo- 

 thele is found in Jamaica, South America to Mexico, Bahamas and either 

 it or a closely related genus, which we will consider as it, in eastern 

 Africa, Madagascar and India. Filistata is known from South America, 

 including the Galapagos, to California and southeastern United States, 

 Bermuda and the Atlantic islands, Mediterranean region, Africa, central 

 Asia, Philippines and Australia. Pellenes is reported from Jamaica, 

 Cuba, Central America to Canada, Europe, Mediterranean region and 

 northeastern Asia. The numbers are so few that the reader can easily 

 analyze the distributions from the data just given. 



Of the 10 American genera which have been found on the mainland, 

 6 are known from South America, 10 are known from Central America 

 and Mexico, 7 are kno^vn from United States. 



The American distribution of Jamaican genera is shown in Table VI.
