Neio Generic Names' for some Entomostraca and Girripedia. 

 By Canon A. M. Norman, F.R.S. &c. 



In preparing for publication a second edition of the Catalogue 

 of the Crustacea in my collection and tracing the generic 

 names of the lower orders in that class I find that the 

 following changes are necessary. 



Cladocera. 



Genus SiMOSA*, nov. nom. 



= Shnocephahis, Schoedler. 



Two genera named Simocepkalus were published almost 

 simultaneously. The name was used for a genus of snakes 

 by Dr. Giinther in his ' Catalogue of Colurabrine Snakes,' 

 the exact date of the publication of which, I learn from him, 

 was October 9, 1858 ; and the name was applied to a 

 genus of Cladocera by Schoedler in a paper read September 22, 

 1858, and as it was illustrated by a quarto plate, it is not 

 likely that it could have been published within so short a 

 time after the reading as October 9. 



Genus Rhynchotalona f, nov. nom. 



In 1861 G. 0. Sars instituted a genus Harporhynchus for 

 the interesting species he was describing — H.falcatus; but 

 that name having been previously (in 1848) employed by 

 Cabanis for a genus of birds, in 1884 C. L. Herrick substi- 

 tuted the name Leptorhynchus — a still more unfortunate 

 choice, for that name had been employed at least three times 

 previously, and it is therefore necessary to supersede it. 



* <rt/xo'y, snub-nosed, 



t pvyp^uToy, having a beak.
