Mr. W. T. Caiman on a neio Pedalion. 



The type specimen of //. Salvini is the very one referred 

 to and figured by Mr. Alston in tlie work above quoted. 



It is witii great pleasure that I connect with this interesting 

 annectant species the name of Mr. Osbert Salvin, its disco- 

 verer in 1873, and one of the editors of the great work in 

 which it is so beautifully figured. 



A Heteromys from Costa Rica, in the Museum collection, 

 also appears to belong to H. Salvini) its hind feet agree 

 ])recisely in their structure with those of the type, but are 

 even shorter, measuring only 2d millim.

The remarkable rotifer Pedalion mirum, discovered by 

 Dr. Hudson in 1871, has been the source of much interest 

 and speculation to zoologists on account of its aberrant form 

 and supposed arthropod affinities. Though it has since been 

 found in several localities, both in this country and on the 

 continent *, it has always been a great rarity, and no allied
