XXVII. — A Contrihufion to the Si/filemntics of the Pedipalpi. 

 By E,. I. PocoCK. 



Part I. — A Revision of the Generic Names of the 

 Amblypygi. 



The first name Introcluccd into tlic ^roup of Amblypygous 

 Pedi]ialpi was reniforme, Linn., wliicli was assifrned to the 

 genus Phalangium (Syst. Nat. ed. 10, p. 619, 1758). Ihni- 

 forme was based upon — (1) a specimen in the Mus. Ludov. 

 Ulr. and indicated in the description by flie letters M. L. V. ; 

 (2) a figure and description of a Pedipalp from Antigua 

 published in Browne's ' History of Jamaica.' The specimen 

 and the figure are representatives of totally distinct species. 

 To which is the name reniforme to be affixed? 



In the case of a genus based upon two species which sub- 

 sequently prove to be generically distinguishable it is custo- 

 mary, in deciding to which of the two the generic name is to 

 be attached, to abide by tiie verdict of the first reviser who 

 fixes the type species either by direct selection or by elimina- 

 tion. Species should bo similarly treated. 



In the case of reniforme^ Linnwus was his own reviser, 

 for in the catalogue of the Mus. Ludov. Ulr. p. 427 (17()-4) he 

 gives a description of reniforme taken from the actual 

 specimen, and this description obviously excludes the species
