25. Paratelphusa (Oziotelphusa) hydrodromus, var. (?) 



This is a small and immature male, and I do not know what to make of it. 

 It is like hydrodromus, but the post-orbital crests are very strongly sinuous, the 

 inner half being oblique and the outer half running into the epibranchial 

 tooth ; they are also more overlapped by, and more in rear of, the epigastric 

 crests.

•26. Paratelphusa (Oziotelphusa) bouvieri, Kathbun. (Fig. 61.) 



Polamou {Potitmon) bouvieri, Mary J. Rathbun, Nouv. Archiv. du Museum (4), VL, 1904, p. 293 («/>( synon.), 

 pi. xii., fig. 5. 



Agrees very closely with Paratelphusa hydrodromus, and differs only in 

 the following particulars : — ■ 



The carapace (at least in adult males) is not so convex; it is closely 

 covered with a fine fiu'furaceous pubescence beneath which it is closely and 

 minutely granular; its antero-lateral borders are much less convex and the 

 lateral epibranchial teeth are larger, more prominent, and sharper ; the oblique 

 striee crossing the postero-lateral borders are more numerous and more distinct ; 

 the postero-lateral borders are less convergent. 



The front is broader, its breadth in the adult being decidedly more than a 

 third the greatest breadth of the carapace, and is less declivous. 



The post-orbital crests are straighter and more transverse, and they run 

 almost to the base of the lateral epibranchial spine. 



The legs are slightly stronger and longer.

The above form is probably only a hill variety of P. hydvodro'iims.
