334 SMITHSONIAN MISCELLANEOUS COLLECTIONS [vOL. 45 



Trouessart (Catalogus Mammalinm, i, fasc. iii, 1897, pp. 662-663) places 

 the following species under it used as a subgenus, gabbi Allen, dcHlippii 

 Cornelia, nigronuchaUs Hartert, brasiltensis Linnaeus. 



Miller and Rehn (Proc. Boston Soc. Nat. Hist., xxx, p. 190, December 27, 

 1901) have included under it (as a subgenus of Lepus) brasiliensis Linn^us 

 and gabbi Allen. 



Major (Trans. Linn. Soc. London, 2d sen, vii, Zool., November, 1899, p. 

 514) regards Tapeti as one of four subgenera (the other three being Limiio- 

 lagus, Romerolagns, and true Sylvilagiis) forming the genus Syivilagus. 



Gray describes Tapeti as follows : " Skull like Lcpus, but with hinder 

 supraorbital notch narrow, the lobes short, with a sharp inner edge ; the front 

 of the lower edge of the zygoma dilated, sharp-edged, porous above, hinder 

 nasal opening rather narrower. Tail, none. Ears short." This description 

 of the skull does not agree with the skulls of Syivilagus niinensis, paraguen- 

 sis or gabbi at hand, and I am at a loss to understand the true status of 

 Tapeti. The available material shows that Tapeti is nothing else than a part 

 of Syivilagus, and it is so here regarded. 



IIL LIST OF THE EXISTING SPECIES OF THE DUPLICIDEN- 

 TATA ARRANGED BY GENERA AND SUBGENERA 



The species under each group are arranged alphabetically. The 

 list includes all the names that are found in Trouessart's Catalogus 

 Mammalium, 1897, and in Miller and Rehn's Systematic Results 

 of the Study of North American Land Mammals to the Close of 

 the Year 1900 (Proc. Boston Soc. Nat. Hist., xxx, December 27, 

 1901) together with the names that have appeared since these twO' 

 works. Those species of which the writer has seen skulls or 

 skeletons are printed in small capitals, those of which he has seen 

 figures of the skulls or skeletons are in italic, and those of which 

 he has seen neither specimens nor figures are in ordinary type.
