106 THE NAUTILUS. 



A fine species in the Naticidae may prove to be a new genus. 



Velutina laevigata Linn. 



The specimens we obtained were the largest and finest I have 

 ever seen. The largest one is 8.2 mm. in length. 



Panomya ampin Dall. 



Of this odd and rare species we were fortunate to obtain sev- 

 eral specimens. 



A report will be published about April, 1919, and will have 

 a full description of each species; and we hope to have figures 

 of most of them. IDA S. OLDROYD, Stanford University, Cali-
