RANA SWINHOANA" Boulenger. 



1903. Rana swinhoana Boulencer, Ann. Mag. Nat. Hist. (7), XII, Nov., 1903, 

 p. 556 (type-locality, Bangkimtsing, Formosa; types, Brit. Mus. Nos. 99. 

 4. 24. 104-105; J. D. La Touche, collector). 



Description of types. — FeTnale. Vomerine teeth in two oblique series 

 between the choanse; head much depressed, sH^litly broader than 

 long; snout as long as the diameter of the orbit, rounded; can thus 

 rostralis obtuse; loreal region not very oblique, concave; nostril 

 equally distant from the end of the snout and from the eye ; interor- 

 bital space as broad as the upper eyelid ; tympanum distinct, one-half 

 to three-fifths the diameter of the eye; fingers moderate, first not 

 extending beyond second; toes entirely webbed; tips of fingers and 

 toes dilated into well-developed disks, which are much smaller than 

 the tympanum; subarticular tubercles rather small; a small, oval 

 inner metatarsal tubercle ; the tibio-tarsal articulation reaches the tip 

 of the snout; skin smooth, granular on the side; no dorso-lateral fold. 

 Brown above, with small darker spots; a dark canthal streak and a 

 dark temporal blotch; a wdiitish streak on the upper lip; limbs with 

 rather indistinct dark crossbars; lower parts white. 



Dimensions. — From snout to vent 80 mm. (Boulenger's original 

 description). 



Remarks. — Doctor Boulenger states that the nearest ally to this 

 species is Rana livida Bly th { = R cMoronota Guenther) , the range of 

 which extends from Darjeeling, in the Himalayas, through the moun- 

 tains of Assam and Tenasserim to Hongkong. 



Habitat. — Thus far only recorded from Bangkimtsing, Formosa, 

 where the types were collected by J. D. La Touche.

 No. 30). 



The outward appearance of the last joint of fingers and toes together 

 with the large disks misled me into believing that this species had an 

 interpolated phalanx between the regular ultimate and the penidti- 

 mate ones, but dissection has failed to discover such a bone, so that 

 it appears safest to refer it to the genus Rana. 



Description. — Adult; Tokyo Imperial Museum, No. 30; Okinawa 

 shima. (Figs. 111-116.) Vomerine teeth in two short series behind 

 the level of the choan»; fiat above, blunt, descending vertically at the 

 tip; nostril much nearer the tip of snout than eye; canthus rostralis
