VESPERTILIO AKOKOMULI. 39 



figure does not belong to V. abramus , which latter spe- 

 cies has a postcalcaneal lobe, an orgaue not represented 

 in the figure referred to. The figures 8 and 9 on plate 57 are 

 those of the V. akakomulie , lege akakömori , but inexact 

 in so far as the point of attachment of the wing-mem- 

 branes «in natura" is the base of the toes and not so high 

 up as is represented in figure 8. 



It seems that no naturalist after Temminck has exam- 

 ined the type-specimens of the V. akakömori in the Leyden 

 Museum. Tomes ^) says «that V. akokomuU probably is 

 a good species". Swinhoe ^) refers that in Hainan and in 

 Canton he has procured bats, determined by Prof. Peters 

 as belonging to Vesperugo ahramus Tern. ( V. akokomali or 

 akakomuli). Dobson in his Catalogue of the Chiroptera, 

 1878, for the rest so complete and exact, and also in his 

 Monograph of the Asiatic Chiroptera, 1876, has nowhere 

 spoken of the Bat in question. 



Now I have carefully examined the specimens in our 

 Museum, labeled V. akakomuli by Temminck ffour alco- 

 holic and one stuffed specimen) and I have not found any 

 difference between them and V. ahramus Tern. , neither 

 in dentition, nor in color, nor in size: the males present 

 the same characteristic peculiarity, sc. the enormous de- 

 velopment of the long bony penis , «which , in proportion to 

 the size of the animal , is much larger than in any other 

 species of Bat", as Dobson remarks •''). Thus Vesperugo 

 akakömori is synonymous with Vesperugo ahramus Teïü. 

 Dobson has only omitted to observe that the ahramus has 

 the incisors of the lower jaw trifid.
