tlic first arc strong and smooth, not '' granular" and "rather 

 weak." The shagreened area of the first and second segments 

 is not flanked by an oblique row of granules, giving them a 

 broadly cuneate appearance. It is noticeable, moreover, that 

 Purcell makes no mention of the strong lobate inferior crest 

 running along the fore margin of the lower side of the fourth 

 caudal segment and abutting against and as high as the 

 U-shaped crest on the third — a feature which has no parallel 

 in other species of the genus. Yet, since Purcell states that 

 the description of P. cristatus mentions no structural charac- 

 ter to distinguish that species from breviinaniis, I can only 

 conclude that the cliaracteristie in question is present in 

 brevimanus. If so, it is not a little singular that neither 

 Thorell (who ''minutely describes both sexes o? brevimanus"), 

 Purcell (who devotes nearly three pages to the species, 

 mentioning all the less important details), nor Kraepeliu 

 say a word to justify the belief in its existeace.

$ . — Colour a tolerably uniform yellowish brown, the terga 

 anteriorly darker, fingers darker ; a broAvn spot at the distal 

 extremity of the femur, patella, and protarsus of the leg. 



Carapace densely and closely punctured; the interocular 

 triangle and the area at the sides of and behind the median 

 eyes smooth ; some coarse punctures on the frontal lobes, 

 and a few granules in front of the ocular tubercle ; studded 

 at the sides with coarse but not close-set granules; about as 

 long as the first and the second and one third of the third 

 caudal segments, and a little longer than the third and fourth 

 segments. 



Terga smooth, polished and punctured, except at the sides 

 and along the posterior border, where, except in the middle 

 line, there are many coarse granules ; the last with the lateral 

 crests weak, granular, the area between the admedian pair 

 quite smooth. 



Stei'iia quite smooth, punctulate, the last obsoletely crested. 



TfaY about three times as long as carapace, slender; fourth 

 segment about twice as long as wide, third considerably less 

 than that, fifth almost three times as long as wide; the 

 superior and superior lateral keels denticulated ; the inferior
