Type. Adult female. B.M. no. 88. 1. 9. 11. Number 595 

 of the Copenhagen Museum. Collected 13th June, 1851, by 

 Prof. Reinhardt. Received in exchange from the Copenhagen 

 Museum. 



Members of this interesting genus are excessively rare in 

 museums, and, so far as I am aware, no other examples 

 of the true E. spinosus have been recorded. 



Besides the type of E. laticeps, the British Museum con- 

 tains three specimens of E. spinosus from Paraguay, and 

 three more have recently come, collected by Herr W. Elirhardt 

 at Joinville, Santa Catherina. 



XXIX. — Remai'ks on the Species of the Genus Rheinardtius. 

 By D. G. Elliot, D.Sc, F.R.S.E , &c. 



Anavs ocelzatus was founded upon a presumable tail-feather 

 of some unknown bird contained in the collection of the 

 Paris Museum. The name was a MS. one, bestowed by the 

 late Jules Verreaux, but never published by him, and the 

 first description given of the feather was one by mj^self in 

 the Ann. & Mag. Nat. Hist. 1871, viii. p. 119. For many 

 years this feather remained in the bird-gallery of the Paris 

 Museum as sole representative of some unknown but evidently 

 extraordinary species, and when, early in 1880, a complete 

 example of a long-tailed pheasant-like bird was brought 

 from Annam, resembling as regards its tail-feathers the one 

 so long in the Mnseum, the name ocellatus Avas conferred 

 upon it and a new generic term Rheinardtius created for it, 

 and under that name the species has been known up to the 

 present time. 



One naturalist, however, evidently did not believe in the 

 identity of the specimen called at present Rheinardtius ocel- 

 latus with the feather so long in the Museum, for in the 

 ' Bulletin de la Societe Zoologique de France ' Mons. Main- 

 gonnat named the Annam examples Argus rheinardti. 



While very familiar with the long feather in the Paris 

 Museum, of which a plate containing a full-size figure is 

 given in my ' Monograph of the ' Fhasianidse,' I had not 

 until lately had an opportunity of examining the Annam 

 bird and comparing it with the feather called Argus ocellatus ; 

 but this, through the kindness of M. Trouessart, 1 have now 

 been able to do, for the single feather, while no longer
