This species is unfortunately misnamed, for it never lives in salt 

 water. It is a permanent swamp species, often frequenting rain bar- 

 rels and occurring from the Atlantic to the Mississippi Valley. Our 

 records are Chesapeake Beach, Md. (Dyar), Newark, N.J. (Brehme) 

 Urbana, 111. (Knab), Washington, D. C, (Dyar), Georgetown, D. C. 

 (Caudell), Springfield, Mass. (Knab), St. Louis, Mo. (Busck).

 hairs in twos after the second abdominal segment ; subdorsal hairs in 

 threes on segments 3 to 7 . Air tube very long, 8x1, the pecten reach- 

 ing nearly one-third. 



The larvae were collected by Mr. Busckin a small pool in a cave in 

 coral cliffs near the ocean in San Domingo and in a large crab hole in a

 condition of the skins is imperfect . The specimens were named ' ' Cu- 

 lex secutor Theob . ' '
