MEXICAN, CENTRAL AMERICAN, AND CUBAN CAMBARI 13 



The words emphasized by me cannot be understood as they 

 stand. But if we conjecture that v. Martens wrote or intended 

 to write, instead of zwrderen (anterior), anderen (other), every- 

 thing is clear : he meant to say, that the inner plane face of the 

 inner part is adjacent to the identical face of the appendage of 

 the otJicr side. 



Thus the whole description is intelligible, and indeed, it is a 

 correct characterization of the chief features of this organ. It 

 is very interesting to note, that already v. Martens attributes to 

 the inner part two lobes, and his second one is clearly the acces- 

 sorv spine, which is not horny in the male of the second form ; 

 v. Martens, consequently, describes this organ of the male of 

 the second form. 



He has also correctly interpreted this organ. There is also 

 in our specimens an outer part, which ends bluntly, and has the 

 anterior margin slightly swollen just below the tip. The inner 

 part is dilated and flattened on the inside, and forms, on the 

 anterior margin, near the tip, a sharp shoulder. Its posterior 

 margin extends considerably beyond the margin of the outer 

 part, which is due to the extreme dilatation of the inner face. 

 Its tip is pointed, and has, in the second form, a rounded, pro- 

 jecting lobe anteriorly. 



In the male of the first form, the tip of the inner part is more 

 slender and thin, almost setiform, but soft (not horny). The 

 projecting lobe is replaced by a slightly procurved, horny spine, 

 which is two-pointed, one point being blunt, the other acute and 

 thin. 



Faxon's figures (1885, pi. 8, f. 5, 5', 5", 5"') are only partly 

 correct. There is hardly any objection to Fig. 5"', which repre- 

 sents the inner view of this organ of the left side of the male of 

 the second form. It shows plainly the pointed tip of the inner 

 part and the lobiform accessory process, as well as the thickened 

 anterior margin of the tip of the outer part. Fig. 5" represents 

 the same organ from the outside. The different parts are recog- 

 nizable, but the outer part is not marked off at the tip, and the 

 accessory lobe of the inner part is rendered incorrectly (as a 

 recurved, blunt hook). Fig. 5' is intended to represent the 

 inner view of this organ of the left side in the male of the first
