The puzzling Anomia. Shell oblong-ovate, thin, upper 

 valve oblique, sometimes smooth, sometimes radiately 

 ridged, ridges distant, warty or almost obsolete ; deep 

 coppery-pm-ple, lower valve silvery-white or yellow- 

 ish. 



Tellma (Bnigmatka, Chemnitz, Conch Cab. vol. xi. pi. !99. 

 f. 1949 and 1950. 

 Anomia rosea. Gray. 

 Anomia naviformis, Jonas. 



Uab. Philippine Islands (in Mango-trees and Nipa Palms, 

 on the seashore) ; Cuming. 

 It will be seen by the numbers of the accompanying 



figures that the shells selected for illustration were intended 

 to represent four species. On further examination, how- 

 ever, I cannot resist coming to the conclusion that they 

 are all varieties of one and the same — the TelUna tenig- 

 i/iaticn of Chemnitz. When attached to narrow stems or 

 sticks the shell assumes an elongated boat form, as in the 

 variety A. naviformis, Jonas, at Fig. 37. The variety, 

 Fig. 38, from Borneo, is smooth, broad, and rather solid ; 

 that at Fig. 39 has a more oblique growth, and is rayed 

 with more or less obsolete warty ridges. It is found on 

 piles of wood forming the wharves at Singapore. The 

 shells represented at Fig. 40 a, b, c, d, which may be re- 

 garded as the typical form of the species, are of a more 

 regular growth, sometimes smooth, sometimes presenting 

 indications of the warty ridges. They were found by ilr. 

 Cuming attached to the ilango-trees and Nipa Palms, 

 growing between tides on the shores of the Philippine 

 Islands, some adhering to the leaves, as at Fig. 40 «.
