Subfamily LEPTOPODIIN^. 



Eyes slender, not retractile, laterally projecting. Preocular and post- 

 ocular spines small or wanting. Basal joint of the antennae slender

Carapace pyriform; gastric region prominent, rounded, and bearing tufts 

 of curved setae; hepatic regions tumid, bearing two pointed tubercles, 

 the larger one above and in front of the smaller; cardiac region separated 

 by shallow grooves from the branchial and bearing a prominent elevation; 

 branchial regions flattened or tumid. Kostrum triangular, acute, and 

 bearing two double rows of curved setae above; it varies considerably in 

 length, being sometimes broadly and sometimes narrowly triangular. 

 The area between the two projecting rims of the orbits is concave. There 

 is no tooth at the posterior margin of the orbit, but there may be a small 

 one a short distance behind it. Eye-stalks constricted at the middle and
