Descriptions of new or little-knoivn Species. 



Lepreus carinatus, sp. n. (Plate XIV. fig. 3.) 



Colour (dry specimen) almost uniformly dark ochraceous, the 

 ocular tubercle and the anterior border of the cephalothorax black. 



Cephalothorax thickly and somewhat coarsely granular throuo-hout, 

 without trace of keels ; its anterior border lightly emarginate ; the 

 ocular tubercle deeply and widely cleft, granular in front and behind, 

 smooth in the middle ; the post-ocular sulcus deep and T-shaped. 



Tergites closely granular throughout, the granulation coarser in the 

 posterior half ; the first six furnished with a conspicuous median 

 granular keel ; the fourth, fifth, and sixth, in addition, with traces of 

 short lateral keels, formed of two or three large granules set in longi- 

 tudinal series ; the seventh tergite furnished with an anterior median, 

 granular, subcarinate prominence, and two lateral, long, conspicuously 

 denticulated keels, which behind almost attain the posterior margin, 

 and in Iront are more or less connected by a transverse row of 

 stronger granules. 



Sternites: the first four smooth, sparsely punctured and bisulcate; 

 the fifth furnished with four obsolete, subgranular keels. 



Tail long and nearly parallel-sided ; the first four segments 

 hollowed above and minutely granular; the first three furnished with 

 ten keels, the fourth with eight ; the superior keels on the first 

 four denticulate, with the posterior denticle the largest ; the superior 

 lateral keel on these same segments also denticulate, but with the 

 terminal denticle only enlarged on the first and second ; the median 

 lateral keel is also denticulate, but less strongly than those just 

 described — it is complete on the first segment, slightly abbreviated in 

 front on the second, and slightly more abbreviated on the third, on 

 the fourth its position is occupied by a few small granules ; the 

 inferior keels are strong and denticulated on the first four segments, 

 but a little less strongly denticulated on the first than on the second,' 

 on the second than on the third, and on the third than on the fourth : 

 the fifth segment minutely and closely granular and shallowly 

 excavated above, with no conspicuous posterior depression and no 

 superior keels, laterally more coarsely granular ; the three inferior 

 keels strong and complete and evenly denticulated throughout ; the 

 spaces between these keels furnished with strong granules, which in 

 the anterior half of the segment are on each side of the middle line 

 arranged in a definite longitudinal series. Vesicle of moderate size, 

 sparsely but distinctly tubercular beneath, without a spine or 

 enlarged tubercle beneath the aculeus, which is of moderate length 

 and gently curved. 



Palpi distinclly hairy, especially on the brachium, manus, and 

 dactyli ; humerus finely granular above and below, tubercular in 

 front, the keels normal, distinct and strongly granular ; brachium not 

 costate, rounded and smooth behind and below, granular above 

 graiuilar and tubercular in front; manus rounded, neither cariiiate 

 nor granular, slightly wider than the brachium ; dacUjli short, both 

 slightly sinuate ; the armature of the dactyli closely resembling that
