Mr, R. I. Pocock on Neotropical Scorpions. 101 
The ocular tubercle situated in the middle of the carapace. 
In Cercophonius, 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 by 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 Jheringiz; but I also refer to it a specimen in the 
British Museum from Coquimbo which I identify as-Cerco- 
phonius brachycentrus of Thorell. 
These two species further differ from C. sqguama 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. 
Urophonius Sheringii, 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 favous spots along the hinder 
border ; segments ‘of the tail irregularly fuscous above and 
at the sides, especially posteriorly ; vesicle flavous ; upper 
surface of the legs, chelicere, and palpi banded or spotted 
with black; digits ferruginous. 
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 posteriorly, not mesially depressed, the last with tae 
abbreviated coarsely granular keels on each side. 
Sternites smooth and polished, minutely punctulate, the 
last tubercular. 
Tail slender, about five times the length of the carapace ; 
the second seement as long as wide and wider than the fifth, 
the segments with lightly 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
