sylz'aticus has had to be renamed Sylz'Hagns florid an us niaHiirus (Thomas, 

 Ann. Mag. Nat. Hist., 7th sen, 11, October, 1898, p. 320; Allen, Bull. Amer. 

 Mus. Nat. Hist., xii, March 4, 1899, p. 13), the latter becomes the type of 

 the genus Sylvilagiis. 



Two other species were placed in this genus by Gray, arteincsia Bachman, 

 and hachmani Waterhouse. 



The name has generally been used by subsequent writers as the subgeneric 

 term for the cottontail rabbits (Sylvilagus Aortdaiuis and its allies) of North 

 America. 



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

 514) uses it in a generic sense for Limnolagus Mearns, Romerolagus 

 Merrriam (both regarded as separate genera in the present account), Tapcti 

 Gray (which I regard as a part of Sy'vilagus), and Sylz'ilagits Gray, which 

 according to Major embraces " S. sylvaticus, etc." 



Trouessart (Catalogus Mammalium, i, fasc. ii, pp. 658-660, 1897) uses it in 

 a subgeneric sense for the following species: sylvaticus Bachman (with the 

 subspecies : transitionalis Bangs, bachmani Waterhouse, alacer Bangs, 

 mcanisi Allen, floridanus Allen, pinctis Allen, arizonce Allen, holzerni 

 Mearns, nuttali Bachman, auduboni Baird, astecus Allen), grangeri Allen, 

 trozi'bridgci Baird, artemisia Bachman, arizonce Allen (with the subspecies 

 major Mearns and minor Mearns), vcrcccrucis Thomas, insolitns Allen, 

 Orizaba Merriam, graysoni Allen, idahocnsis Merriam. 



Of these the last I regard as the only member of the genus Bracliylagus 

 proposed by Miller as a subgenus, and trozvbridgii Baird as a member of the 

 subgenus Microlagns of the genus Sylvilagus. 



Miller and Rehn (Proc. Boston Soc. Nat. Hist., xxx, December 27, 1901, 

 184-188) have included under Sylvilagus, as a subgenus of Lcpus, the fol- 

 lowing species : arizonce Allen, arizonce coniinis Allen, arizonce major 

 Mearns, . arizonce minor Mearns, baileyi Merriam, floridanus Allen, 

 floridanus alacer Bangs, floridanus audubonii Baird, floridanus aztccus Allen, 

 Aoridanus caniclunis Miller, floridanus cliapmani Allen, floridanus holzneri 

 Mearns, floridanus mallurus Thomas, floridanus nicarnsi Allen, floridanus 

 pinetis Allen, floridanus rigidus Mearns, floridanus sanclidiegi Miller, 

 floridanus subcinctus Miller, floridanus transitionalis Bangs, floridanus 

 yucatanicus Miller, grangeri Allen, graysoni Allen, insolitus Allen, 

 nuttallii Bachman, orizibce Merriam, z'crcecrucis Thomas. 



Recently Thomas (Ann. Mag. Nat. Hist., ser. 7, viii, December, 1901, pp. 

 534, 539) following Major has raised Sylvilagus to generic rank. 



I consider Sylvilagus a distinct genus, embracing all the forms given by 

 Miller and Rehn under their subgenera Sylvilagus, Microlagus, and Tapeti 

 (also including Lepus truei Allen, which is found in their list under the 

 subgenus Limnolagus) and all the South American Leporidae. It is also used 

 in the present paper as a subgeneric term for all the species of Sylvilagus 

 just mentioned, except the group embracing Microlagus here regarded as 

 another subgenus of Sylvilagus. 



TAPETI 



Proposed by Gray (Ann. Mag. Nat. Hist., 3d sen, xx, 1867, p. 224) as a 

 generic term for Lcpus brasilicnsis Linn.eus, which, as the only named 

 species, is the type.
