in Locustidce). In Oryllus capensis regenerated tarsi still 

 show three joints, but the new tarsus in this case is in some 

 respects more massive than the normal one. Tlie third joint 

 is nearly equal to the first, while in the normal tarsus it is 

 considerably longer than the latter. Finally, the second 

 joint, which in the ordinary tarsus is very small and almost 

 entirely hidden, is quite visible in the regenerated one. This 

 difference is particularly noticeable in the case of the posterior 

 limbs'^. 



So far as the nature of the tarsal regenerations is con- 

 cerned in Acridium ruhellum I cannot at present speak, my 

 experiments with this species not being yet completed f.

FoK many years every student of the Chiroptera has known of, 

 and hoped for the publication of, the magnificent series of plates to 

 illustrate this group of auimals drawn by the famous draughtsman 

 J. D. L. Franz Wagner under the direction of the late Prof. Peters. 

 A foretaste of their quality was given by the publication of a few 

 of them in illustration of some of Prof. Peters's papers, but other- 

 wise, although many of them are now more than 30 years old, no one 

 had been able to see them except at Berlin or at Genoa, to whose 

 Museum Prof. Peters had given a set. 



Now at last an instalment of them is published in illustration 

 of a general work on Bats by Dr. Paul Matschie, accompanied by 

 further plates drawn by that author's deceased wife. 



This work will be of the greatest utility to all students of Bats, 

 and abounds with evidences of the author's care and of the richness 

 of the materials on which it is based. Synoptical tables are given 

 of all the genera, subgenera, and species ; and although some of those 

 we have tried have not quite responded to the call made upon them, 

 yet they give a most useful index to the characters mainly relied upon 

 by the author in distinguishing the various forms. 



• It should be stated that the regenerated tarsus represents one of the 

 organic positions of stability intermediate between the actual normal form 

 and an ancestral one. 



t In Locustidae and Gryllidse the tibia of regenerated anterior limbs 

 does not possess the tympanic apparatus which exists on the original 

 limb.
