594 NOMENCLATURE AND DISTRIBUTION OF THE GENUS PYTHIA. 



It is also very constant in its characters. I am unable to 

 ascertain in what way it is referred to by D'Argenville as 

 mentioned by Pfeiffer. 



Pfeiffer records Var. B. a small, pale grey variety, I presume 

 from the same locality scarcely worthy of record. 



5 Pytiiia avellana, Reeve. 



Scarabus avellana, Eeeve, Conch. Icon., Vol. xii., genus Scarabus 

 1860, Spe. 27, pi. iii., fig. 27. 



Habitat. The Island of Madura, near Java. Reeve, on the 

 authority of Cuming. 



Pfeiffer has not taken any notice of this species in his Mono- 

 graph on the Auriculacea published in 1876. Paetel has followed

 Catalogue to refer to, otherwise it might clear up difficulties and 

 doubts.
