Judging from Leydig's description and figures, this Bemodex 

 is a short and wide species, very like I), bovis in appearance and 

 proportions, the posterior end of the body also pointed as in that 

 species. The abdomen is not longer than the cephalothorax. Pseudo- 

 segments of the body well defined, the annulations being thick and 

 sharp. Eggs oval in shape. 



Host : A Bat {Phjllosioma hastatum), Surinam. 



BIBLIOGEAPHT. 



A list of oyer two hundred and tliirty papers dealing with Demodex (chiefly with the 

 form occurring in the dog and the disease with which it is associated) has been compiled 

 by the author, and a complete list would be much longer. Owing to the great increase 

 in the cost of printing and paper it has been necessary to omit this list from the present 

 pamphlet. The more important systematic works on the subject are mentioned in the 

 short history of the group given on page 9. A list of a hundred papers will be 

 found at the end of Gmeiner's paper (Arch. Dermat. Syph. Wien, vol. xcii., 1908, and 

 Zeitschr. f. Tiermed. Jena, vol. xiii., 1909). Another good list is that given by Huber in 

 his ' Bibliographie der klinischen Entomologie ' (Hexapoden, Acarinen), Jena Heft 2, 

 18y9, pp. 1-8. Numerous papers are, however, omitted from these two lists.
