Diagnosis. — Front sinuous, slightly four-lobed. Second lateral 

 tooth large, blunt, or arcuate. Wrist M^ithout distal groove. Several 

 roundish color spots on upper three-fifths of outer surface of hand. 

 Dark color of propodal finger continued a short distance on palm. 

 Abdomen of male arcuate at tip. 



Description of the typical form (Plate 156, figs. 1 and 2). — Carapace 

 about ^(o as long as wide; regions well marked, convexity variable, 

 surface coarsely granulate. A transverse raised granulate line nearly 

 across the branchial reigon and in line with the last sinus of the 

 antero-lateral border; a similar line runs obliquely backward from 

 the anterior margin of the last tooth; shorter transverse lines, some- 

 times Vvavy, are found on anterior half or two-fifths of carapace. 

 First (or outer orbital) tooth of lateral margin triangular, blunt, 

 Httle prominent; second tooth separated from first by a shallow 

 rounded sinus, and larger and nearly as advanced as first, either 

 blunt-pomted and with arcuate outer margin, or lobiform; third and 

 fourth teeth still larger, prominent, with arcuate outer margins and 

 acute tips, the third directed obUquely inward, the fourth forward or 

 sKghtly inward; fifth tooth shorter, with acute tip and straight outer 

 margin. In general the outlines of the teeth form a regular curve from
