2o CRUSTACEA OF ALABAMA. 



clawed, the shorter ramus 2- or 3-jointed ; inner rami of the other swimming feet (except 

 occasionally in males) 2-jointed ; fifth feet nearly as in Canthocamptits, which in several 

 respects the genus resembles. Some eight species are recognized with none of which 

 our American form agrees, though sharing some characters of L. similis, Claus, and L. 

 curticaudata, Boeck. Although our knowledge of the species rests upon a single gather- 

 ing containing only the female, it may be safe to apply a specific designation to the above, 

 which, in connection with the habitat will be easily recognized. 



Laoponte mississippiensis, s P- «■ 



(Plate I, Figs. 14, 15; Plate II, Fig. 18; Plate VI, Fig. 5.) 



Laoponte similis ? Herrick, Final Report, etc., 1884. 



Body stout, segments angular, not heavily spined, front produced into a prominent 

 rostrum, (our figure represents the whole body as too stout and the second seta of the 

 caudal stylets too long), eye large ; antennas six- or seven-jointed, the fourth joint small 

 and bearing a rather short process ; antennules nearly as long as the antennse, palp mi- 

 nute, apical segment with four setae ; maxilliped oval, with a claw as long as the main 

 joint ; first foot with the inner ramus 2-jointed, the basal segment being very long, ex- 

 ceeding the entire outer ramus, terminal segment very short, clawed and finely pectinate 

 behind ; outer ramus 3-jointed ; swimming feet with 2-jointed inner rami ; fifth foot with 

 a broad basal joint with three setae within, terminal segment oval, with five unequal spines. 



Genus Bradva, Boeck, (1872.) 



Antennse very short, 6-, 7-jointed ; antennules of moderate size longer, than anten- 

 nae, with a 2- or 3-jointed palp; mandibular palp large; maxillipeds rather large, outer 

 branch (firstfoot-jaw of Brady) much as in Calanida; ; first four pairs of feet nearly 

 alike ; fifth pair small, not lamellate. 



This peculiar genus is not yet well circumscribed and defined, and it is much to be 

 regretted that lack of time prevented from ascertaining how far the western species 

 agrees with the generic characters of the European form and thus determining the va- 

 lidity of the assumed generic criteria. That our species is a member of the genus can 

 not be doubted, but the hurried examination which could be devoted to it failed to cover 

 the entire structure. 



Bradya limicola, Herrick. 



Am. Nat. Feb., 1883; Final Rep., 1884. 



Body flattened ; free margins of the segments of the dorsal carapace rather long ; 

 little separation between abdomen and thorax ; abdomen cylindrical, rather long; stylets
