 sample which was collected in the eastern Pa-

Hugh M. Smith __ 94 2 females, 0.99 mm. 



Remarks: Although this is a cosmopolitan 

 species, it was observed in but one sample. 

 Possibly its small size permitted most of the 

 specimens to pass through the meshes of the 

 nets employed or perhaps it is not too abundant 

 in the waters sampled.
