274 COLE 



distally, where the dorsal corners are continued into 2 short, knob-like 

 processes. 



Caudal segment moderately long, curved slightly upward, reaching 

 slightly past the middle of the second coxal joint of the fourth pair of legs ; 

 narrow, swollen distally, slightly bifid at the apex as seen from above ; 

 armed with a few short bristles and a longer one on the dorsal side. 



Eye tubercle moderate, taller than the dorsal tubercles, bluntly rounded. 

 Eyes of good size ; near the apex. 



Proboscis equals trunk to base of caudal segment, broadly ovate, some- 

 what narrower in side view. 



Chelifori over half as long as proboscis; second joint about equal to 

 first, clavate, with a number of short bristles at its distal end ; third joint 

 short, less than half as long as second, subchelate, the somewhat triangular 

 pieces representing the fingers of the chela probably being the rudiments 

 of those organs in the larva. The third joint has one short spine. 



Palpi 9-jointed ; when [fully extended but little longer than the pro- 

 boscis, about 3 joints reaching beyond its tip; jj, i and 3 short; jj.2 

 and 4 longer; j.2 somewhat longer than 7.4 ; jj.% to 9 short and decreas- 

 ing gradually in size, sub triangular, being bulged ventrally toward their 

 distal ends, and here armed with numerous short bristles. The fourth 

 joint has scattered similar bristles ; the remaining (basal) joints practically 

 unarmed. 



Ovigera of the female equal to the palpi in length ; j.i short ; 7.2 longer ; 



/3 shorter again ; jj.\ and 5 longest, each about equal to J.i +7.2 ; j/'.6, 



1, and 8 successively smaller; j.g larger again, about equal to j.i ; y.io 



very small, and armed with 2 denticulate spines, as is also the case with 



j.g and/,8. Aside from this the appendage is almost unarmed, except 



for 3 or 4 short curved spines on/. 6. 



Legs stout, somewhat less than twice as long as body; c.i short, 

 square, with a short rounded protuberance dorsally; c.2 longer, consid- 

 erably narrower at proximal end, where it joins c.i, somewhat bulged dis- 

 tally below ; c.$ equals c.i ; f. comparatively short and broad, without the 

 thumb-like protuberance at the distal end usual in Ammothea, but with 

 several bristles at this point and scattered along its dorsal border ; shorter 

 than coxal region; /.i and /.2 each about equal to/., both with more or 

 less wavy dorsal borders, where they have a row of bristles of irregular 

 size; ts.\ not unusual, armed with a few small bristles, especially ven- 

 trally; ts.z equals about four fifths of /.2, rather stout, but slightly arcu- 

 ate ; with a row of small bristles dorsally, 3 stout spines on the heel, and 

 a row of short slender spines along the sole. Claw half as long as ft. 2, 

 rather strongly curved ; aux, cL about half as long as cL
