Heraarh_s.- Only a few of the Bo-.vden Anemias can "oe referred 

 to this variety -^nd they are soniev/hat dou.htiul. Ail of them are 

 small, none exceeclino' 16 mm. in latitude or altitude. A. micro- . 

 ■?rammata is a v/ell-defined species which occurs in the ?amoa silex 

 beds and Ohipola marl. ^t variety indeeisa . is. hov/ever, of douht- 

 fiTl validity. The radial striations, which constitute the charac- 

 teristic feature, are very fine indeed on the specimens at hand 

 and occiir only on very lir-ited portions of the shell. They are 

 visible only under the microscope. Most of t?ie Anomias in the 

 Bowden fauna are here referred to A. simplex d'Orbip-ny since they 

 are smooth except for occasional exagp-erate-'' incrementals. A-rngr- 

 ently simples itself m.ay have suggestions of radial striae and 

 for that reason the advisability of establishing a va.riety for 

 the 3ov;den forms ^vith mere siiggestions of radial striation is 

 questioned. At the present time, however, it seems advisable to 

 retain the varietal name.
