324 MK. F. E. BEDDARD ON THE ANATOMY [Apr. 9, 



Spinturnix vespertilionis (Dufour). This small Mite was present 

 on the wing-membrane of Rhinolophus ferrum-equinimi, and 

 was identified by Professor E. Trouessart, of Paris, to whom 

 Mr. Hirst had kindly forwarded my specimens.

I possess, through the kindness of Dr. Charles Hose of Borneo, 

 an example of a Frog from that country, which at first appears 

 to be referable to the genus Megcdophrys, and which at least 

 comes nearest to — if it be not identical with — Ceratophrys 

 nasuta of Schlegel. It appears to differ, however, from that 

 species in one very important point and in one or two features 

 ■of minor importance. The single example was in an excellent 

 state of preservation, and I am therefore able to contribute some 

 facts to the anatomy of this genus, which, save for many external 

 ■characters and certain osteological featm-es, is apparently quite 

 unknown to zoologists. It is necessary, however, to preface my 

 account of its anatomy with an attempt to fix accurately the 

 species to which this account refers. The species M. nasuta was 

 originally named and figured by Schlegel*. Our subsequent 

 knowledge of the external characters of the sjaecies is chiefly due 

 to Cantor t, Dumeril & Bibron J, Giinther §, Boulenger !|, who 

 hns summed up and added to the previous descriptions, and, latest 

 of all, Werner IT". Darwin** has figured the heads of Megalophrys 



* Handl. Dievk., Atlas, pi. iv. fig. 72. The leaf-like appendage upon the nose is 

 represented as being directed forwards, which is not the case with vay example.
