PREFACE. 
“ You have many forms not found by Bunker or previou.s observ- 
ers. * * * A number of your bivalves are probably new. The 
Scalpellum you sent is a new form which I shall name S. Stearnsii 
with your permission. It is a very distinct species, more nearly allied 
to thè tossii S. Pfeifferi Weithofer of thè Vienna Basili (Miocene) 
than to any living species. * * * 
“ Of thè Brachiopoda sent, two are new species, and one of them I 
propose to name Terebratella Stearnsii.” 
In accordance, therefore, with Prof. Pilsbry’s suggestion, I publish 
this list, which contains all thè species obtained by me, over half of 
which were so rare and found in such limited numbers and at such 
long intervals that they are retained in my private cabinet; of thè 
others I have abundance for exchange and for sale. 
There are in thè collection 72 named species not found in Bunker; 
32 species remain as yet undetermined, many of which will prob- 
ably be found to be new to Science. In Rotella, Tapes, Cytheria, 
etc., are many beautiful color varieties which I believe have not been 
before recorded. 
Preliminary descriptions of a number of thè new species collected 
have been published in The Tfautilus for Becember, 1890, and Jan- 
uary, 1891. An illustrated paper on thè Brachiopoda, by Wm. H. 
Ball and H. A. Pilsbry, will appear in thè Proceedings of thè Acad- 
emy of Naturai Sciences of Philadelphia, 1891; and another paper by 
H. A. Pilsbry, in thè sanie Proceedings, will describe new Gastropoda 
and Pelecypoda.
