THE SPECIES OF AEGLA — SCHMITT 485 



spinules ; second and third hepatic lobes evident, but poorly marked. 



Large hand stubby, palm thick and heavy looking, much swollen, 

 almost subglobular in appearance in some specimens, scabrous. Mov- 

 able finger with a low swelling or rather a small, more or less obso- 

 lescent spinulose lobe on outer margin near base. Palmar crest low, 

 outer margin thick and blunt-tubercular ; the almost tuberclelike ser- 

 rations are furnished with short, more or less transverse rows of small, 

 pointed, corneous scales, few in number. Carpus rough-scabrous, 

 the only longitudinal ridge being the one above the inner marginal 

 row of spines; this ridge appears doubled, as it carries two longi- 

 tudinal series of more or less transverse rows of small, pointed, almost 

 spinulelike corneous scales. Anterior internal lobe or angle of carpus, 

 though at times subacute, more usually blunt, generally furnished 

 with several scattered, more or less subequal, almost spinuliform, 

 corneous scales; occasionally the apical one is a little larger than 

 the others. Merus armed above with a longitudinal series of blunt 

 tubercles topped with one, two, three, or more small, pointed, corne- 

 ous scales ; anterior margin fine denticulate, without lobe or swelling. 

 Inner margin of ventral surface of ischium armed with three to four 

 more or less subequal, more or less equispaced, low, but definite and 

 well formed, conical tubercles or spines with subacute to acute corne- 

 ous tips, one anterior, one posterior, and one or two in the interspace 

 between the first two. 



Dorsal anterior angle of epimeron of second 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 

 here and there usually on the epimeron of one side only. The speci- 

 men selected as the type is, in this respect only, perhaps one of the 

 most atypical specimens in the entire type lot. It is the largest speci- 

 men and has two little scales or tiny denticles on the right epimeron 

 and one tiny "cornule" on the left; the next largest specimen has 

 nothing of the sort on either dorsal epimeral angle; otherwise, only 

 four specimens out of the original lot of 20 have any trace of spinule, 

 denticle, or scale on the right or left epimeron. In about its middle 

 third the sternite between the bases of the chelipeds of the type and 

 one other specimen is somewhat swollen or raised up along the median 

 line, more so anteriorly, where it carries a perhajDS adventitious, tiny, 

 corneous prickle or spinule, than posteriorly. In the next largest 

 specimen this swelling is much less marked. Also, it is unarmed, as 

 it is in the rest of the specimens at hand. Most of these have the 

 median elevation more or less obsolescent, yet have an appreciable, 

 though not very noticeable, convexity of the underside of the sternite; 

 in a few of the smaller specimens it is not evident at all.
