WHITE, Charles A. -Continued. 



In this article the origin of the Umonidae is 

 traced and an explanation for their distribu- 

 tion is given. The paper is illustrated by 6 

 plates, the originals of the figures being the 

 property of the U. S. National Museum. 

 Viilo stantoni, new species, of the Laramie 

 Group, is proposed for a specimen formerly 

 referred to Unio danx Meek and Hayden.

Some changes in crustacean no- 

 menclature. 



/'roe Biol. Soi . Wash., xvn, Dec. 27. 1904, 

 pp. 169- 172. 

 These changes are necessitated by the dis- 

 covery that several genera of Weber's "No- 

 menclator entomologicus." 1795, have been 

 ignored by subsequent authors. Alpheus 

 Weber and Ligia Weber are synonyms of 

 Cancer Linnaeus; Crangon Weber takes pre- 

 cedence of .47pAfwsFahricius; I Id mar us Weber 

 may be used in its present sense, for the lob- 

 sters; Parthenopi Weber is equivalent to the 

 later Lambrusoi Leach; Daldorfia is proposed 

 asa new generic name for Parthenopi Fabri- 

 cius; Euryala Weber= Corystes Latreille 1802; 

 Idotea Weber is a synonym of Emerita Grono- 

 vius.
