THE SPECIES OF AEGLA — SCHMITT 499 



angle of first hepatic lobe low, scabrous-tubercular; second and third 

 lobes very poorly marked. 



Hands large, oval, moderately inflated, and without usual lobular 

 tooth on prehensile margin of immovable finger ; movable finger like- 

 wise without such a tooth; there is no lobe on the outer margin of 

 the movable finger, and the palmar crest, though not prominent, is 

 distinctly present, thick, low, and in cross section broadly triangular ; 

 dorsal surface of crest faintly, shallowly, or more or less obscurely 

 excavate; the crest is scabrous with an outline that is more slightly 

 irregular than obscurely serrate; serrations may be spinule tipped.

Figure 59. — Aegla humahuaca, new species, male holotype: a, Dorsal view; b, lateral view 

 of anterior portion; c, sternum of third and fourth thoracic somites; d, inner ventral 

 margin of ischium of left cheliped; e, lateral view of second abdominal epimeron. a, b, 

 natural size; c-e, twice natural size. 



Ridge of carpus of cheliped above inner spined margin not very 

 prominent, low and broad and in small part only slightly scabrous; 

 the armature of the inner margin of the carpus is not so definitely 

 spinelike as in most other Aeglas; here it consists more of spinelike 

 tubercles, perhaps only the most anterior of the series may be so 

 designated, as the next three or four are more or less tuberclelike in 

 appearance; the posterior one or two of these are indeed very low, 

 blunt, and scabrous; anterior internal lobe or angle of carpus scarcely 

 more than obtuse angled ; this angle is armed with one or more small, 

 low-conical but more or less sharp-pointed corneous scales; upper 

 longitudinal margin of merus blunt angled, hardly more than a 

 scabrous ridge marked or armed with a row of fairly well separated, 

 short, subacute, corneous scales; the anterior margin of the merus 

 is finely denticulate, but no lobe or forwardly directed projection
