nearly at right angles, the common tubercle broadly grooved above. 

 Posterior lateral eyes long, reniform, .their anterior margins in a line 

 with the posterior margins of the anterior median eyes and their 

 posterior margins in a line with those of the posterior median eyes, 

 their distance from the anterior margin of the carapace subequal to 

 their distance from either median eye of the other side ; the 4 

 median eyes forming a rectangle which is somewhat broader than 

 long, the anterior medians small, much more than a diameter apart, 

 the posterior medians ovate and a little shorter, their distance 

 from the laterals about i more than their distance from one 

 another. 



Legs. Tibia of first leg as long as the metatarsus and \ of the 

 tarsus. Tibia of second leg with about 5 external spines or spini- 

 form setae. Patella of third leg with 1-3 apical spines overhanging 

 the upper posterior part of the distal edge and with a single spine 

 nearer the middle of posterior upper surface (besides the anterior 

 band). All the tarsi spined below. 



Total length 35 mm. ; length of carapace 12 ; length of metatarsus 

 of first leg 4. 



GEN. GALEOSOMA n. g.
