THE NAUTILUS. 103 



by its brown aperture, has several well marked varieties. Var. 

 stellata is white Avith coarse brown markings and low spire, 

 taeniata white with a broad subsutural b&nd,flaveola is yellow 

 with a white aperture and Candida is an albino form. Speci- 

 mens from Sarmar, Philippines, collected by Mr. E. L. Moseley, 

 are all uniform in color, representing the dark reticulated form 

 (Thes. Conch., fig. 248). This might bear the varietal name 

 of samarensis.

 It seems unfortunate that the pale abnormal form should 

 have to be the type of the species, instead of the beautiful ame- 

 thystina. To the latter both Bolten and Lamarck refer to the 

 same figures by Martini (Conch. Cab. ii, Tab. 46, f. 491, 492). 

 Many specimens of the var. mantichora show the same malfor- 

 mation of the typical form an elevated ridge at the periphery.

The dark brown specimens are usually decorticated. The 

 orange-yellow form might bear the varietal name of A. g. auran- 

 tia, n. var.
