SYSTEMATIC ACCOUNT OF THE SPECIES. 97 



than upper eyelid; tympanum scarcely visible; first finger shorter than second; 

 tips of fingers and toes not dilated and hardly swollen at all; fingers slender, 

 longer than in B. longinasus; toes sUghtly webbed; subarticular tubercles large, 

 single; both metatarsal tubercles well developed; a tarsal fold; tibiotarsal 

 articulation of adpressed hind limb reaches midway between insertion of fore 

 hmb and tympanic region; skin itself smooth, with small wrinkles and many 

 tubercles arranged in more or less regular longitudinal series ; parotoids greatly 

 developed as in Bufo longinasus. 



Colour (in alcohol) : — Above almost black, a conspicuous hght stripe from 

 snout to vent, this stripe is extended laterally on the eyelids and thus widens to 

 a rhomb-like figure on the head. The light stripe is bordered on each side by 

 a narrow band of deep velvety black. Below, the throat is mahogany-brown, 

 the fore part of the chest and angles of the jaws deep brown; the belly is white, 

 profusely spotted and streaked with dark brown, as are also the Ups and upper 

 surfaces of the hmbs. 



Dimensions: — Tip of snout to vent 21 . mm. 



Width of head 9. mm. 



Fore limb from axilla 11.2 mm. 



Hind Umb from vent 25 . 2 mm. 



Vent to heel 14 . 5 mm. 



When Bufo ramsdeni was described only the type, a female, was known, 

 while of B. longinasus the type also was unique and a male. There was nat- 

 urally on our part a slight feeUng that possibly these might represent the oppo- 

 site sexes of a species in which the sexual dimorphism was much greater than 

 usual. Happily we can now state definitely that this is not the case, since 

 careful collecting at Los Hondones has revealed three other specimens, an adult 

 and two young males. The adult pair are of the same size, about 30-35 mm. 

 from snout to vent. The male agrees very closely with the female described 

 in all essential characters, except colouration. This is quite different, being 

 uniform chocolate on all the upper surfaces, while the ventral surfaces are like 

 the female. 



All of these examples, the only ones found, were caught in a deep forest, 

 in a very wet area on the road from Guantanamo to Los Hondones, and some 

 fifteen miles north of Guantanamo. Here the road, only about five feet wide, 

 passes between two large moss covered boulders called "Las Comadres." On 

 each occasion when toads were found it had been raining heavily and the ground
