This widely distributed Bat was recorded from the Tunisian Chotts 

 by M. Lataste in 1885, and again, in 1885, from El Hammam 

 de Cabes, at the eastern extremity of these salt-water lakes of 

 Tunisia.

 stantine. 



The most easterly point in the distribution of this Bat recorded by 

 M. Lataste was Cape Okas, near Bougie. This new locality brings it 

 close to Tunisia, in which province, however, it has not yet been 

 observed. 



Order INSECTIVORA. 



Family I. Macroscelidid^. 



Genus Macroscelides.

This species has been found at Mount Santa Cruz, Oran (in the 

 Tell), whence also probably came the specimen from which Duvernoy 

 described the species. It likewise inhabits the high plateaux, and has 

 been recorded from (north to south) Ain Oussera, about 3000 ft. 

 above the sea, Djelfa, 3792 ft., Ain el Ibel, about 3700 ft., and also 

 from the slopes tending to the Sahara, such as Laghouat, 2437 ft., 

 and Bou Saada, 1900 ft. The specimen recorded by me from Biskra, 

 360 ft. above the sea-level, was not obtained at this elevation, but 

 from the hills behind, at what height I cannot say. M. Lataste 



belongs to the genus Hyalomma (Koch). The species seems to be either the 

 Ixodes flavipes oi "Koch OT the I. vespertilionis of the same author; it is not 

 possible in the present state of our knowledge to identify it with certainty 

 from immature specimens, but it is probable that the two species are not 

 really distinct ; both have been recorded as bat-parasites, the former by Kolenati, 

 the latter by Koch. According to modern classification this Acarid would 

 belong to the genus Hyalomma, not Ixodes. 



" The other Acarid, of which there are numerous examples, was found by 

 Dr. Anderson upon the same Bat and upon Plecotus aimttis ; it is one of tho 

 creatures described by Kolenati as forming the genus Peplonyssus ; the species 

 is probably his P. cnic'ij)lica. These Peplonyssi are all bat-parasites ; but, 

 although I am not sure that the fact has been publicly recorded, I think there 

 can be no doubt that all the species of the genus are larval forms of Ixodidse, 

 the adults of which we may or may not be acquainted with, but which cannot 

 at present be identified with the larvae."
