The following may be used for names preoccupied though 

 with different gender terminations : 



Rhodla Bell, 1835, for Herbdla'Uilne Edwards, 1834. (Hcrh- 

 sthim Leach in Desmarest, Diet. Sci. Nat., XXVIII, 301, 1823, 

 Macrura.) 



Grapsilhis MacLeay, 1838, for Trapezia Latreille, 1825. (Trape- 

 zium Humphrey, Mus. Calonnianum, 1797, Mollusca.) 



HypopeltariumX Miers, 1886, for Peltarion Hombron and 

 Jacquinot, 1852? {Peltarlum. G. Fischer de Waldheim, Bull. 

 Soc. Imp. Nat. Moscou, XVII, part 1, 106, 1844, Coleoptera.) 



Eiiry pan open f^% A. Milne Edwards, 1880, for Panopeus Milne 

 Edwards, 1834. (Panopea Menard, Ann. Mus., IX, 135, 1807, 



*Ortmann, Zool. Jahrb., Syst., YII, Heft .3, 443, 1893, unites Xanthodes 

 with Xantho. 



t Since the publication of my 'Synopsis of the American Species of 

 Palicus Philippi (= Cijmopolla Roux),' pp. 93 to 99 of these Proceedings, 

 Professor Jeffrey Bell and Dr. Hilgendorf have kindly sent me copies of 

 the original description of Palicus. Though brief, it agrees with Ci/mo- 

 polia. Dr. Philippi was doubtless soon convinced of the identity of his 

 genus with the earlier one, as the complete description and figure which 

 he promised to publish in Wiegmann's Archiv never appeared. 



X Hypopeliarium was substituted by Miers, ISS'i, for Peltarion (name 

 preoccupied) and has been in use ever since. 



§ Admitting that Eurytium Stimpson, 1859, is a distinct genus.
