4. Myotis oxygnathus BIontioelH. 



cJ T, ? 8 ; Djebel Taya, N. Algeria. Felirnary 1011. (Also some iu spirits.) 

 (W. Rothschild and E. Hartert.) 



It is probable that all specimens from N. Africa hitherto referred to Ji. mi/otis 

 {Vespertilio tnnriims of Dobson and earlier anthors) are really referable to the 

 smaller species described from S. Italy by Monticelli. 



[This Bat inhabits a side-chamber of the great cave on Mount Taya, east of 

 ( 'onstantine. This is the Bat mentioned by Kobelt, Reisecvinnpvnnqeii aus Alyerien 

 viid Tunis, \i. 285, which Herr von Berlepsch " had recognised as a new species, 

 but not yet — iu 1885 — described." Doubtless this was an erroneous statement, for 

 " Herr von Berlepsch " {i.e. Freiherr Hans von Berlepsch, who was at that time 

 staying at Hammam Meskoutine), had no knowledge of Bats, and could never have 

 intended to describe it. — E. H.] 



5. Fennecus zerda Zimm. 



¥ 5 ; 27 km. south of El-Golea. 



Agrees closely with a specimen from the Natron Valley, N. Egypt, except that 

 the bullae are smaller. Another specimen from Algeria in the Museum collection, 

 however, has the same large bullae as Egyptian exarajiles, so that this character 

 would seem to be variable. 



[The Feunec is entirely restricted to the sandy desert, and especially to the 

 dunes, where they are not entirely without vegetation. It does not seem to occnr 

 near Biskra, or anywhere north of Touggonrt. We have seen the traces as far 

 south as the Erg between Hassi Meksa and Oued Saret. Near In-Salah it does 

 not seem to exist, although there is plenty of sand. It seems to be fond of 

 beetles.— E. H.] 



6. Gerbillus pyramidum F. Cuv. 



? 14; Igosten, near lu-Salah. 



c? 19, 21, ? 20, 22, 23, 28, 29 ; In Salah. 



Very much like the brighter coloured of the Egyptian specimens in the Museum, 

 but not so bright as those from Tripoli which formed the basis of my G. pyramidiiim 

 tarahuU. 



[These little beasts were lirought in in numbers by boys, who obtained them 

 in the " gardens," or better palm-groves of the oasis. — E. H.] 



T. Grerbillus gerbillus 01 iv. 



¥ C ; 27 km. south of El-Golea. 



<?1G; In-Salah. 



cJ 32, ¥ 31 ; Oaed el-Abiodh, near In-Salah. 



<f 38 ; 30 km. south of Fort Miribel. 



Quite like typical Egyptian (}. i/rrbilhts. 



8. Dipodillus campestris roszikae Thus, 

 t? 15, l(i, 24 ; (Jbetma, near Biskra. (W. Rothschild and E. Hartort.)

 S 15; Igosten, near In->Salah. 

 cJ 17, 18, ¥ 24, 25, 20, 27 ; In-Salah.
