The 2 teeth of the 1st jomt of the specunen illustrated by Miiller and 

 the one I examined are quite similar. Miiller apparently interprets 

 the 2 bristles, which I consider to be on the posterior surface of the 

 2nd joint, to be on the inner lobe of the 3rd joint. This is quite 

 possible, but difficult to verify, because the suture between 2nd and 

 3rd joints is not visible on specimens I examined. The 4th joint 

 illustrated by Miiller (figs. 43, 46) does not have the short terminal 

 bristle present on the specimen I exammed. This may have been 

 overlooked by Miiller, or possibly the number of bristles on the 4th 

 joint varies slightly within the species. 



Sixth lunb (fig. 8/) : Fu'st endite with 2 bristles; 2nd endite with 5 

 bristles; 3rd endite with 4 bristles; end joint with 5 (?) bristles; single 

 bristle in place of epipodial appendage. 



The appendage illustrated by Miiller (1894, pi. 3, fig. 54) is quite 

 sunilar to the one I examined with the exception of bearing 8 bristles 

 on the end joint. Since the end joint I examined belongs to an im- 

 mature specimen, it is possible that it has fewer bristles; because of the 

 position of the 6th limb on the slide, I was not able to see the end joint 

 clearly, so it is likely that more than 5 bristles are present. 



Furca (figs. 8^-^): Each lameUa with 6 claws; claws 1, 2, 4 being 

 stout claws, and claws 3, 5, 6 slender claws; claw 3 shorter than claw 4; 

 each claw separated from lamella by suture; claw 1 with stout spines 

 in row proxknally on lateral margm, slender spines distaUy on lateral 

 and medial margins, and 1 large spine near middle of medial margin. 

 Remaining claws with spines along medial and lateral margins; lamella, 

 in area of distal and proximal claws, with hairs. 



Miiller (1894, pi. 3, figs. 34, 53) figures a furca with the 3rd claw 

 almost equal m length to the 4th claw. This suggests that the length 

 of the 3rd claw may be somewhat variable within the species. Miil- 

 ler's figures do not show peripheral spines on claws 3, 5, 6. It seems 

 probable that these were overlooked by Muller. In this regard, it is 

 interesting that Brady and Norman (1896, p. 672) state that the larger 

 furcal claws of Pseudophilomedes infatus are ciliated on the edge and 

 in the figure of this appendage (1896, pi. 59, fig. 10) show claws 3 and 

 8-10 without marginal spines. In view of MuUer's omission of mar- 

 ginal spines on slender claws, it seems likely that they also were over- 

 looked by Brady and Norman. It would be most unusual and seems 

 quite unlikely for spines to be absent from the slender claws, especially 

 claw 3.
