THE SPECIES OF AEGLA — SCHMTTT 455 



as with a small corneous scale or spinule (present in type), which 

 may represent or take the place of an orbital spine; offset usually 

 with slight notch or incision next to anterolateral spine ; palmar 

 crest thick, almost obsolescent, upper surface not impressed or ex- 

 cavate. Dorsal anterior angle of epimeron of second (in lateral view, 

 apparent first) abdominal somite normally and usually rounded off 

 and unarmed ; very rarely does one find a corneous scale or denticle 

 or two or even a small spinule, and then usually on epimeron of 



one side only papuda (p. 483) 



if'. Not even distal third of rostrum concave from side to side without 

 noticeable intervention of dorsal carina ; rostrum carinated virtually 

 to its distal extremity or else anterior fourth or so of free portion of 

 rostrum so thickened that rostral carina and any longitudinal 

 troughing that dorsal surface of rostrum may otherwise have either 

 side of carina becomes more or less completely obliterated in this 

 terminal fourth of rostrum. 

 Z)\ Dorsal anterior angle of epimeron of second (in lateral view, 

 apparent first) abdominal somite rounded off and unarmed. 

 ^. Margins of palmar crest appreciably and noticeably upturned, upper 

 surface of crest definitely impressed or excavate ; crest some- 

 what or quite subdiscif orm ; movable finger with a definite 

 though sometimes small, but always spined or spiny lobe or 

 projection on outer margin near base ; hands more or less sub- 

 ovoid in outline; rostrum normally not exceeding eyestalks by 

 as much as length of cornea ; rostral carina not even faintly 

 traceable behind anterior margins of protogastric lobes; orbital 

 spine and extraorbital sinus definitely present ; latter always 

 distinct though sometimes small. 

 F^. Palmar crest conspicuously large and expanded, subdisciform, 

 noticeably excavate, much as if it had been impressed or 

 pinched out while soft with the ball of one's thumb ; margin 

 of crest obscurely serrate at best, scabrous and small spinulose ; 

 rostral carina furnished with an irregularly alternating dou- 

 ble (in very small part, at times triple) row of small corneous 



scales odebrechtii (p. 487) 



¥^. Palmar crest only moderately large or expanded and, though 

 somewhat rounded off, not particularly subdisciform, more or 

 less longitudinally troughed ; margin of palmar crest definitely 

 serrate ; rostral carina almost smooth and naked appearing 

 on top, at most sparsely and well-nigh microscopically scaled 



where it appears scaled odebrechtii paulensis (p. 490) 



IP. Margins of palmar crest not noticeably upturned, crest at best only 

 slightly or narrowly and very shallowly, if at all, troughed or 

 excavate, not particularly impressed looking ; crest more sub- 

 rectangular in outline than subdisciform ; at most only a slight 

 lobe or projection on outer margin of movable finger near base; 

 margin of finger rough-spinulose and usually with a few larger 

 spinules on a slight elevation near base of finger, better seen in 

 smaller than in larger specimens. 

 i^. Definite orbital spine or spinule present, set off from anterolateral 

 spine by a small, narrow sinus or notch ; palmar crest thinning 

 out to its outer margin, which is sharply though not deeply 

 saw-toothed, and sharply small-spinulose, not troughed or ex-
