AND BATEACHIANS OF BARBABY. 159 



tubercles ; a tarsal fold. Above usually with large insuliform, dark-edged, reddish- 

 brown spots. Male with a subgular vocal sac. 



From snout to vent 140 millim. 



This fine large Toad appears to be peculiar to Barbary. It has beea found in every 

 part of Morocco yet investigated, and is very common all over Algeria as far south as 

 the limit of the Sahara, M. Lataste having obtained it at Biskra, Bou-Saada, and 

 Laghouat. It is found near Tunis, and M. Lataste met with it at Tozeur, Gafsa, and 

 Ferriana, but not at Cabes, where Bufo viridis and Uana esculenta are abundant. 



I have given a figure of B. mauritanicus in Proc. Zool. Soc. 1880, pi. li. 



3. Bufo vulgaris, Lauren ti, 1768. 



Interorbital space broader than the upper eyelid ; tympanum more or less distinct. 

 First finger extending scarcely beyond second ; toes at least half webbed, with double 

 subarticular tubercles ; no tarsal fold. Brown or dull olive aoove, with darker spots ; 

 parotoid glands with a dark outer margin. Male without vocal sac. 



From snout to vent 130 millim. 



The Common Toad of Europe and Palsearctic Asia is rare in Algeria, and at present 

 only known from Algiers {Strauch, Latade), Tlemsen {Boettger), and Bona, where 

 Dr. HagenmiiUer states it is not unfrequent. It is undoubtedly the rarer of the three 

 toads of Barbary. Camerano has recorded it from Larache in Morocco. It has not 

 yet been obtained in Tunisia. 



Fam. 3. HYLIU^. 

 1. Htla, Laurenti, 1708. 

 Pupil horizontal. Vomerine teeth. Tongue subcircular, entire or slightly nicked 

 and more or less free behind. Fingers free or webbed, toes webbed. 



Of this large genus a single species occurs in Europe and round the Mediterranean. 



1. Hyla aeboeea, Linnaeus, 1766. 

 H. viridis, Guicheuot. 



Fingers webbed at the base ; tympanum distinct ; upper parts perfectly smooth, belly

The Tree-Frog of Barbary belongs to the var. meridionalis, Boettg., 1874 {=zperezi, 

 Bosca, 18S0, larytonus, Heron-Royer, 1881), which is uniforai green, without a dark 

 stripe along the side of the body, and with the green colour extending to the sides of 

 the throat. It inhabits the south of France, North Italy, Spain and Portugal, the 

 Canary Islands and Madeira, and Barbary, where it is common all over the Tell. It has 

 been found everywhere in Morocco. 



This variety is figured by Bosca, Ann. Soc. Esp. x. 1881, pi. ii. figs. 7-10, and by 

 Heron-Royer, BuU. Soc. Zool, France, 1884, pi. ix.
