large, movable segment of the antenna is represented considerably- 

 wider than in my drawing (fig. 117, a). 



In Bell's figure of the type female (see my fig. 4, pi. 250) the cara- 

 pace is broad behind, the teeth of rostrum and orbit are equally 

 advanced, the outer sides of the orbits diverge anteriorly, the first 

 four lateral teeth are subequal in size and similar, the fifth tooth 

 smaller but not rudimentary. The anterior third of the carapace is 

 smooth, the remaining two-thirds granulated. 



While the illustrations of the two authors at first glance seem 

 irreconcilable, it is possible that some of the differences are attribut- 

 able to exaggeration of sexual characters. 



Color. — -General color brown; feet with alternate rings of reddish 

 and brown (Bell) .

Meas^irements. — Male (Galapagos Islands), length of carapace 16.7, 

 width including spines 16.3, width excluding spines 14, fronto-orbital 

 width 9.7 mm. 



Range. — Bay of Panama; Galapagos Islands. 



Material examined. — Panama; A. Milne Edwards; 1 young male 

 (Paris Mus.). Galapagos Islands; received from British Museum; 

 1 male (Paris Mus.). 



Other records. — It is possible that the carapace figured by Cano*^ 

 belongs to this species, in which event the long filiform stalks from 

 the antennal region may be considered as foreign growths.
