TWO VARIETIES OF RANA ARVALIS.

literature on Asiatic Herpetology, I came to the conclusion that these 
specimens were identical with Dr. be Bedriaga’s long forgotten var a 
asiatica , this supposition being corroborated by the same-habitat 
and by the sprinkled throat and belly, in the latter res¬ 
pect an analógon of the Italian Rana Látásiéi Blgr. 
After this historical sketch I shall pass on to a close description of 
the external characters 1 2 * of Rana arvalis Nilss. var. asiatica 
de Bedr. 
Habit and proportions as in the typical form; snout in some 
specimens very obtuse, in one individual as obtuse as in Rana fusca Bős. 
Coloration very aberrant ; dorsal surface (in alcohol) greyish brown, often 
powdered with brown; spots large, 8 dark brown or reddish brown, in 
regular rows, sometimes more or less confluent, situated along the 
sides of the broad, light-greyish vertebral stripe, and below the light dorso¬ 
lateral folds ; a series of large dots on limit of dorsal and ventral surface, 
often confluent ; two large spots on each eyelid and on both sides of occipital 
region always present; loreal and supralabial stripes as well as temporal 
spot (streak) as in the typical form; humeral spots present; fore limbs 
with irregular spots, hind limbs with crossbars, the latter ones sometimes 
fusing on tibia to irregular designs; hind surface of thighs gray with 
small white warts ; lower surface whitish or yellowish powdered with 
gray, especially on gular and pectoral region, in other specimens the 
whole lower surface being profusely strewn 
with grey spots and dots even extending over the 
whole ventral surface of hind limbs; in the latter-mem 
tioned specimens a light, unspotted streak is to be seen extending from 
about middle of gular region to middle region of sternum, resembling by 
this feature Rana Latastci Blgr. or Rana gr aeca Blgr. 
As will be apparent from the above description var. asiatica 
de Bedr. mainly differs from the other specimens of R . arvalis by the 
very large and broad, regularly disposed spots on the dorsal surface, 
being in this respect very like R. esculenta L., as well as by the 
partly or totally sprinkled or powdered lower surfaces. The detailed 
examination of its osteological markings, in comparison with the typical 
form, shall be contained in my Monography on the European and Asiatic 
species of Brown Frogs ({(Ranae fuscae»). 
1 Anatomical observations will be contained in my mentioned Monography. 
2 Larger than in any specimens of typical Rana arvalis Nilss. or its var. 
Wolterstorf fi t somewhat approaching in this respect R. macrocnemis Blgr.
