Description. — Perhaps only a small species; my material of this 

 form is limited; the largest specimen at hand, a male, in length of 

 carapace and rostrum together measures 20 mm.; the male holotype 

 is just 1 mm. shorter. 



Carapace moderately convex, front of moderate width. Rostrum 

 broad and somewhat stubbily triangular; bluntly carinated nearly 

 to the anterior extremity, noticeably troughed or excavate either side 

 of carina, which broadens out and becomes more or less lost in the 

 general surface of the carapace at a level about halfway between the 

 level of the epigastric prominences and the anterior borders of the 

 protogastric lobes, these last take the form of a low, somewhat arc- 

 uate, blunt elevation or obsolescent ridge ; the epigastric prominences 

 are fairly well developed and nodular or near rounded-tubercular. 



Orbital sinus moderately wide, only moderately deep, fairly deep 

 as compared to A, odehrechtii; orbital spine small; extraorbital 

 sinus is quite shallow and, though small, is relatively moderately 

 wide as compared with A. odehrechtii. 



Anterolateral spines small, stubby, and only moderately advanced 

 beyond the orbital spines (in some apparently more or less worn 

 individuals the orbital spines are nearly on a level with antero- 

 lateral ones). First hepatic lobe set off from anterolateral lobe by 

 a fairly wide, relatively good-sized notch; anterolateral angle of the 

 first hepatic lobes a little produced and subacute, carrying a small 

 corneous granule or denticle, lateral margin of lobe scabrous; second 

 and third hepatic lobes, though not much more so, are a little better 

 marked than in A. odehrechtii. 



Large hand relatively of good size, broadly oval, stockily built, 

 with palm rather thick and swollen toward outer margin. Movable 

 finger with a small, definite, though not particularly conspicuous, 

 scabrous lobe on outer margin near base. 



Inner margin of palm with a well-developed, impressed or exca- 

 vate crest, having its outer margin somewhat parallel to the dorsal 

 margin of the palm proper, not nearly so subdisciform as in A. 

 odehrechtii^' margin of this palmar crest more or less definitely serrate, 

 serrations marginally scabrous or fine denticulate or corneous gran- 

 uled, perhaps even small spinulate at or on apices of serrations. 



Ridge of carpus of cheliped above spined inner margin more or 

 less well developed, scabrous-nodular; large anterior spine of series 

 arming inner margin of carpus may be as large and tliick as if it
