Subgenus III. — Oziotelphusa, Miiller. 

 Type : Oziotelphusa hydrodromus (Herbst). 



No spine on upper border of merus of chelipeds ; no large spines or teeth 

 — other than perhaps the external orbital angle and the lateral epibranchial 

 tooth — on the antero-lateral borders of the carapace. 



The epigastric crests are sharpish and are in advance of and quite 

 independent of the post-orbital crests. 



The exopodite of the external maxillipeds carries a long, strong, plumose 

 flagellum. 



The cervical groove runs in the direction of the outer orbital tooth, becom- 

 ing indistinct just behind the post-orbital crests. 



As the generic name Hydrodromus is occupied, P. Mullein's name, Oziotel- 

 phusa, may stand for this subgenus, though not in the sense proposed by that 

 author. 



The Indian species may be tabulated as follows : — 



I. The free edge of the "front" proper and the antennular edge of the 

 front are separate : — 



i. Post-orbital crests ending well in rear of the lateral epibranchial 

 tooth, which is small . . . . . .P. hydrodromus. 



ii. Post-orbital crests ending almost on a level with the lateral epi- 

 branchial tooth, which is prominent and acute . . .P. boiwieri. 

 II. The free edge of the front is identical with the antennular edge ; legs 

 long and slender, the propodite of the 2nd pair more than three times 

 as long as broad . . . . . . .P. sp.
