2o6 General Notes, [February, 



(_From the American Naturalist^ February, 1883.) 



A Blind Copepod of the Family Harpacticid^. — The interest 

 now centering upon these animals, which through peculiarities in 

 their habitat have disperfsed with important organs, may warrant 

 the mention of a case of the disappearance of the eyes in an order 

 of Crustacea in which it has not been hitherto noticed so far as I 

 know. 



While collecting marine Copepoda in the Gulf of Mexico a 

 gathering was taken from a very slightly saline marsh, a ditch 

 passing through the marsh affording the only water of sufficient 

 depth in which to use the net. This ditch is about eighteen inches 

 in breadth, but of moderate depth, and extends continuously for 

 some distance ; it is so shaded by high salt sedge grass as not to 

 be found save by accident. The gathering here secured proved 

 to contain a new species of the sub-family Longipediinae and 

 closely allied to the genus Bradya established by Boeck in 1872 

 for a marine Copepod dredged in rather deep waters about North 

 Europe. 



The American species, which has been named Bradya liniicola 

 in allusion to its muddy habitat, was found to lack in both sexes 

 the pigmented eyes which in other Harpacticidse are so con- 

 spicuous in the center of the forehead or on either side. It is to 

 be regretted that lack of opportunity to repeatedly collect this 

 interesting species, and to endeavor to ascertain if truly pelagic 

 species also inhabit our waters, robs this discovery of much of its 

 interest. — C. L. Herrick.
