vertical bars ; as in many species of Rana, some specimens have a 

 yellow median stripe, extending from the tip of the snout to the vent : 

 limbs with dark cross-bars. Lower parts white or pale yellow, throat 

 sometimes spotted with brown. Lis golden-green, veined with black 

 and with a black cross. 



This species agrees very closely with E. doriae, in which the 

 wales also show an enlargement of the head and a swelling on the 

 posterior jjart of the interorbital region, as 1 have described and figured 

 in Ann. Mus. Geneva (2) XIII, 1893. p. 328, pi. VIII. fig. 1, thus 

 foreshadowing the condition in 1{. pilcata. 



However there is no flap, and this e.\traordinary development 

 appears to justify the establishment of a new species, althougii it is not 

 i4npossible that the future discovery of intermediate specimens may 

 necessitate the degradation of the species to varietal rank, so close is 

 the agreement in other respects. The only characters which can be 

 adduced as distinctive of Eana pilcata, apart liom the Hap, are tin- 

 greater interorljital width in males, and tiie shorter inner metatarsal 

 tubercle as compared with the inner toe, the measurements of adult. 

 male and female /i". doriae, 57 and 55 mm. long from snout to vent 

 being. 4 mm. for the tubercle, and G for the toe.
