particularly natural rafts operating through long geologic time ; and the paucity 

 of mammalia was finally a killing argument against a purely theoretical land 

 connection. 



Mr. Leng recalled in support of the drift and hurricane theory the fact 

 that specific identity between Floridian and Cuban forms was in fact largely 

 found in the seashore and strong flying insects. 



In reference to the relation between West Indian and Yucatan insects. 

 Dr. Lutz cited tables he had prepared from the Petrunkevitch catalogue of 

 Spiders showing only 4 5/10 per cent, of the genera as common to the two 

 regions. 



Mr. Harris said he could add to the data on Cicindelidae, Tetracha sp. 

 and Cicindela trifasciata from Grand Cayman. 



The secretary read a letter from Col. Wirt Robinson pointing out an error

Mr. Hall exhibited butterflies caught in the Black Mountains, X. C, in 

 June, 1912, with photographs of the region, which was elevated about 2,300 

 feet above the sea. He commented on the small number of diurnals, 29 species 

 in all, and spoke of the construction of a logging railroad, from Black Mt. 

 Station into the mountains, which will facilitate collecting in future. 



This paper was discussed by Messrs. Schaeffer, Davis, Engelhardt and 

 Leng, all of whom had had some experience in the southern mountains, and 

 it was suggested that it was necessary to collect in varied environments to 

 secure many species, and especially along the summits of the ridges, often 

 more open than their flanks, for butterflies. 



Mr. Harris made an "Exhibition of Exotic Genera of Cicindclida; " show-
