II. LIST OF NAMES APPLIED GENERICALLY OR SUBGENER- 

 ICALLY TO THE EXISTING HARES, RABBITS, AND PIKAS 



ABRA 



Proposed by Gray (Cat. Mammals, Birds, etc., presented by B. H. Hodg- 

 son to Brit. Mus., 2d ed., p. 11, 1863) as a subgenus of Lagoinys. 



Type Lagoiitys (Alva) curziniicc Hodgson from the Himalayas of Sikkim, 

 India. 



Preoccupied by Abra Le.\ch, 1818, a genus of Mollusca, fide Palmer, North 

 American Fauna, No. 23, pp. 71, 860, January 22,, 1904. 



BRACHYLAGUS 



Proposed by ^Miller ( Proc. Biol. Soc. Washington, xni, p. 157, June 13, 

 1900) as a subgenus of Lcpus for L. idahocnsis Merriam, the only species and 

 the type. In the present paper it is considered a distinct genus. 



CAPROLAGUS 



Proposed by BIytli (Journ. Asiatic Soc. Bengal, xiv, 1845, p. 247) as a genus 

 to include Lcpus hispidus Pearson. 



Blyth (Cat. Mam. Mus. Asiat. Soc. Calcutta, 1863, p. 133) subsequently 

 replaced Caprolagus hispidus in the genus Lcpus. 



Gray (Ann. Mag. Nat. Hist., xx, 3d sen, 1867, p. 225) under the misprinted 

 lame Carpolagus regarded it as a distinct genus for Lepus hispidus Pearson. 



Trouessart (Catalogus Mammalium, vol. i, fasc. iii, p. 664, 1897) places 

 two species under Caprolagus as a subgenus of Lcpus, hispidus Pearson, and 

 nctscheri Schlegel, the latter being regarded in this paper as the type of the 

 genus Nesolagus Major. 



Major (Trans. Linn. Soc. London, 2d sen, vn, Zool., p. 514, November, 

 1899) regards Caprolagus as a distinct genus containing the three species 

 sivalcnsis Major, valdarnensis Weith, and hispidus Pearson, the first two 

 extinct. He also uses the name in a larger sense for a group, including (i) 

 Caprolagus, (2) Nesolagus, (3) Oryctolagus, (4) Sylvilagus (the last con- 

 taining (a) Lininolagus, (b) Romcrolagus, (c) Tapcfi, and (d) Sylz'ilagus), 

 contrasted with a Lcpus group containing the one genus Lcpus (this the same 

 as the genus Lcpus of the present paper).
