The ocular tubercle situated in the middle of the carapace. 



In CercophoniuSj of which squama^ Gervais, is the type, 

 and, so far as I know, the sole representative — a species which 

 occurs both upon the west coast of South America and in 

 South-east Australia — the teeth of the median series are 

 represented bj a host of close-set granules, arranged appa- 

 rently without order in from three to five rows ; and the ocular 

 tubercle is placed in front of the middle of the carapace. 



I select as the type of this genus the species described 

 below as Jheringii; but I also refer to it a specimen in the 

 British Museum from Coquimbo which I identify as Cerco- 

 2)honius hrachycentrus of Thorell. 



These two species further differ from C. squama in having 

 the lower surface of the tail coarsely granular beneath in 

 front, the lower surface of the feet furnished with long white 

 hairs, and from five to six pairs of spurs upon the lower sur- 

 face of the feet of the two posterior pairs. In C squama the 

 last sternite of the abdomen and the anterior segments of the 

 tail are not granular, and the lower surfaces of the feet in 

 question are clothed below with short hairs and armed with 

 only two pairs of spines. 



UropJionius Jheringii^ sp. n. 



Colour flavous, nigro-maculate ; the carapace with its ante- 

 ocular portion black in the middle, flavous at the sides ; the 

 tergites fuscous at the sides, with a fuscous spot on each side 

 of the middle line; four clearer flavous spots along the liinder 

 border ; segments of the tail irregularly fuscous above and 

 at the sides, especially posteriori}^ ,• vesicle flavous ; upper 

 surface of the legs, cheliceraj, and palpi banded or spotted 

 with black ; digits ferrug-inous. 



Carapace exceedingly finely granular above at the sides ; 

 the anterior border almost straight, but the posterior border 

 with a distinct median notch ; the ocular tubercle in the 

 middle, grooved, like the area behind and in front of it, 



Tergites almost entirely smooth, minutely granular laterally 

 and jjosteriorly, not mesially depressed, the last with two 

 abbreviated coarsely granular keels on each side. 



Sternites smooth and polished, minutely ])unctulate, the 

 last tubercular. 



'Tail slender, about five times the length of the carapace ; 

 the second segment as long as wide and wider than the fifth, 

 the segments with liglitly convex lateral outlines ; the superior 

 and superior lateral keels smooth and rounded on all but the 

 first segment, where they are feebly granular or tubercular; 

 the lower surface of the anterior three segments irregularly
