Skull practically as in sinensis, though the buUas appear to 

 average rather smaller. 



Dimensions of the type (measured on a rather shrunk 

 skin) : — 



Head and body 380 mm. ; tail 30 ; hind foot 83 ; ear 65. 



Skull: greatest length 81 ; basilar length 59 ; zygomatic 

 breadth 37"5 ; length of nasals (diagonally) 37 ; interorbital 

 breadth 16; palatal foramina 19 x 7*5; length of tooth-row 

 (on alveoli) 14'7. 



Another specimen has a hind foot measuring 87 mm. 



Ilab. Formosa; type from Baksa. 



Tt/pe. Adult male. B.M. no. 93. 12. 5. 6. Collected 

 4th "March, 1893, by P. A. Hoist ; presented by Henry 

 Seebohm, Esq. Three young skins also received from the 

 same source. Another specimen obtained on Mt. Arizan by 

 Mr. A. Owston's collectors. 



This hare may be readily distinguished from L. sinensis by 

 its much paler colour, that animal having the pale rings on its 

 dorsal hairs varying from buffy to ochraceous, thus giving a 

 very much warmer tone to the whole animal. 



it is, however, to be noticed that Consul Svvinhoe recorded 

 L. sinensis as a native of Formosa *, and that tlie one adult 

 skin (no. 62. 12. 24. 16) of his collection sent as from the 

 island is certainly more like sinensis than formosus. Wiiether, 

 however, both forms occur in Formosa, or whether this 

 specimen has been wrongly labelled, are questions which can 

 only be settled when the mammal fauna of the island is more 

 completely known. But considering the uniformity among 

 themselves of all the specimens, young and old, that are 

 unquestionably from Formosa, I am inclined to think that 

 the specimen referred to has been incorrectly labelled.
