On the back of the card is written: ‘‘Sent by Garrett as mzcrostoma. 
No.’’ One specimen. In a letter to Dr. Hartman, Aug. 5, 1882, 
Mr. Garrett says: ‘‘The shell I sent you as P. mzcrostoma Pse., of 
which I have only four examples on a tablet, was taken in the same 
locality where I obtained Pease’s type specimens. If, as you suggest, 
it is a hybrid, it can only be a cross between faéa and radiata, as there 
was no other species inhabiting that part of the valley. I have other 
shells from the same locality which I take to be hybrids between the 
two former species (No. 4310?). It is evident that Pease changed 
the names of some of his MS. species after I left Honolulu in 1863.”’ 
On Sept. 8, 1880, Garrett wrote: ‘‘ The shell I sent you as mzcrostoma 
is correct unless Mr. Pease shifted the name to another species. I 
named the shell and collected many examples on the trunks of trees 
near the ground.’’ See under No. 4108. The example resembles 
some of the specimens of vadiata Pse., included under No. 
4132, gv.
