1. Ehinolophus ferrum-bquinum Schreb. 



San Cristobal, Minorca. 



The Greater Horseshoe Bat is evidently one of the commonest 

 species in Minorca, as we ourselves found examples in two of the 

 caves we visited, and the natives kept bringing in further speci- 

 mens as they explored the different caves on our behalf. But in 

 no case were large numbers found together, one or two being all 

 that were to be obtained in any one cave. 



2. Ehinolophtjs hipposideros Bechst. 



Inca, Majorca. 

 San Cristobal, Minorca. 



All the specimens obtained of the Lesser Horseshoe Bat were 

 found in caves. 



3. Plecotus atjritus L. 



Eecorded by Barcelo from Majorca and Iviza, and described to 

 us as found in a cave at San Cristobal, Minorca. So windy a 

 country is probably not very favourable to the Long-eared Bat. 

 "We ourselves did not see any specimens. 



4. Ybspertilio serotinus Schreb. 

 Recorded by Barcelo from Majorca and Iviza. 



5. Ptbrtgistes nootula Schreb. 

 Majorca (Barcelo). 



6. Pipistrellus pipistrellus Schreb. 



Eecorded as common by Barcelo. Not seen by ourselves, the 

 Bats flying round the houses in Minorca proving to be the next 

 species. 



7. Pipistrellus kuhli Natt. 

 a-c. San Cristobal, Minorca. 



Shot in the close neighbourhood of the village. The flight of 

 this species struck us as very similar to that of its near ally our 

 British Pipistrelle. 



8. Myotis myotis Bechst. 



Minorca (Eaufis fide Barcelo). There was also a specimen, 

 presumably from Majorca, in Don Miguel Eiutort's collection at 

 Inca. 



9. Myotis oapaocinii Bonap. 

 S . Inca, March 26. 



Found in a crevice in the " Cueva de Santa Magdalena," a 

 limestone cave in a hill a couple of miles from Inca. In another 

 crevice close by we found a pair of Miniojitenis schreibersi, the 

 occuiTence together of the two species being just as described in
