86 PATAGONIAN EXPEDITIONS : ZOOLOGY. 



carchiopJiaga in the Rio de la Plata must have been entirely fortuitous, 

 this species is here included, since its capture there in several instances im- 

 plies its occasional occurrence on the coast of Patagonia.

 Ogmorhinus Peters, Monatsb. Akad. Berlin, 1875, 393, footnote. New 



name for Stenorhynchus, preoccupied in carcinology and entomology. 

 Stenorhynchotes Turner, Zool. Challenger Exp., pt. Ixviii, 1888, 63, foot- 

 note. Not adopted, but mentioned as a modification of Stenorhyn- 

 chus that could have been advantageously adopted in place of 

 Ogmorhinus. 

 As has long been known, the generic name Stenorhinchus F. Cuvier, 

 1826, modified by Lesson in 1827 to Stenorhynchus, and by its proposer, 

 in i^2g,io Stenorhy7icus,\s preoccupied by 5y^;/o;'//;';/(:////5 Lamark, 18 18, 

 for a genus of Crustacea, and again in 1823, and still again in 1825, for 

 different genera of insects. On this account Peters in 1875 proposed to 

 replace it with Ogmorhinus. But there appears to have been already an 

 earlier name than Ogmorhinus, as recently shown by Palmer, namely, 

 Hydrurga Gistel, 1848, which should of course be adopted in place of 

 Ogmorhinus. 



Hydrurga leptonyx (Blainville).
