5. Batea catharinensis Miiller 



Pelican Island, Barbados, May 13, 1918. 3 specimens 



Batea catharinensis was discovered at Desterro, Brazil, and in 

 1865 Fritz Miiller created the genus for it. No members of the 

 genus were again met with until 1900 when some specimens were 

 found near Woods Hole, Mass., and described by S. J. Holmes as 

 Batea secunda. The specific differences which this author points 

 out, however, are very slight and the two species will probably 

 prove to be the same. Batea catharinensis has also been found at 

 Chesapeake Bay, Skull Creek, S. C, mouth of May River, S. C, 

 and now at Pelican Island, Barbados. 



6. Pontogeneia verrilli Kunkel 



Pelican Island, Barbados, May 13, 1918. 1 specimen 



In 1910 B. W. Kunkel described this species from Bermuda 

 and this single specimen now from Barbados marks the second 

 record. 



7. Maera inaequipes (A. Costa) 



Pelican Island, Barbados, May 13, 1918. 46 specimens 



This species has been reported from the Azores, Mediterra- 

 nean, Bermuda, Cuba, and South Africa ; and the present record 

 is the first for Barbados. 



8. Elasmopus rapax A. Costa 



Pelican Island, Barbados, May 13, 1918. . 48 specimens 



This species has been reported from Norway, British Isles, 

 France, Azores, Bermuda, Gulf of Mexico, Jamaica, Cuba, and 

 now for the first time from Barbados.
