species, the editor of that edition brackets it as being Scarabus 

 imbrium of Montford, I presume in his Conchyliologie Systema- 

 tique, Vol, ii., 1810, p. 307, so that in reality this species has 

 been twice saddled with the name of imbrium, first by Adams 

 and Reeve in 1850 as shown above, and again by Woodward. 

 Adams and Reeve's name would not stand good because Montford 

 in his Conchyliologie Systematique, Vol. ii,, p. 307, 1810, had 

 described the well known species Pythia scarabceus of Linneus, 

 (Helix scarabceus, Linn.) under the name of imbrium. Pfeiffer 

 altered the name in 1853. 



Habitat. On the authority of Cumiug, Pfr., gave the habitat 

 of this species in the Brit. Mus. Cat. as the Philippine Islands, 

 and on the authority of A. Adams, as Celebes and Borneo in 

 1857. Peeve in his Monogroph in 1860, gives no habitat, 

 although his specimen figured was from Cuming's Collection. I 

 have not seen Issel's work on the Mollusca of Borneo, published 

 in 1874, otherwise he would have settled the point. 



The Scarabus imbrium, figured and described by Kuster in 

 Martini and Chemnitz Conchy lien-Cabinet, Sp. 1, pi. 1, fig. 1, 2, 

 5, p. 8, 1844, is Pijthia scarabaus of Linneus.
