but has also, in consideration of our great loss, sent back all 

 those which were given to him unconditionally. Such con- 

 duct deserves the highest praise. 



Other contributions may be briefly mentioned and we desire 

 to express our great obligations for them to the several donors. 



Dr. W. Newcomb sends us four species and nine specimens 

 of select Santo Domingo shells, which were much desired and 

 add greatly to our collection. 



R. E. C. Stearns, contributes forty-one species, one hun- 

 dred and twenty-three specimens of California marine shells, 

 some of which species proved new to our collection. 



W. G. Binney has sent us 15 species and 70 specimens, 

 which are of more value than the number would seem to 

 indicate, being mostly types of new species. 



T. Bland has also kept us constantly in mind, and sent us 

 51 species, 809 specimens of West India shells, desirable for 

 exchanges. 



From A. Salle, of Paris, we derive 28 species, 44 speci-

 Domingo. 



Through our constant benefactor. Col. Pike, we have re- 

 ceived a box containing 131 species and 360 specimens of 

 marine shells from Mrs. Lacroch ; this contribution is particu- 

 larly rich in Mitra and Plcurotoma. 



Mr. H. Hemphill, of Oakland, California, has laid us under 

 obligations by sending us an unusually satisfactory collection 

 of 259 species and 1,300 specimens of California shells, which 

 makes our representation of that faunal region almost a com- 

 plete one. 



In European species we have been favored with large con- 

 tributions from Dr. Kobold, Dr. Boll and Mr. Sandberger. 



Rev. Mr. Carpenter, missionary to Burmah, has brought 

 us 30 species of land and fresh-water shells collected by him 

 in that region. 



J. G. Jeffreys has again favored us with a small but ex- 

 ceedingly satisfactory collection of Chitons, being all the 

 species found in Great Britain. 



The foregoing, with some minor contributions from various 

 sources, make up a total of 41 packages, containing 1,763 

 species, 19,342 specimens received during the ten months to
