The conchological work accomplished during the year is sununed 

 up by Mr. AY. II. Dall. Honorary Curator, as follows: 



The curator lias continued his work of revising and sunnnarizing the groups of 

 American bivalves. The revision of the fossil S2:)eeies (Tertiary), those of the general 

 collection (recent), and of the American recent species all proceed together, so that 

 for the most part concluding the work on a group means that the si)ecimens in the 

 collection belonging to that group liave been brought np to date. The work which 

 has chiefly occupied the curator during the past year has been (1) the ])reparation 

 of a report now finished, Imt not yet printed, on the newly discovered l^'ocene of 

 Alaska, and (2) the revision of the family Veneridse, one of the largest and most 

 interesting of all the groups of Invalves, including 137 Auierican species not includ- 

 ing those of sonthern South America. TheAvork on the recent species, including the 

 description of 22 new ones discovered during the research, is completed, ])ut the fos- 

 sil forms will require further study as comjirising many undescribed species. 



Mr. Bartsch, under the supervision of the curator, has continued his researches in 

 the Pyramidellidte of the Pacific coast, a wholly unexpected influx of undescribed 

 forms having come to light l)y search in the sand and gravel reserved for the scrutiny 

 of the student of Foraminifera. The nomenclature being in a l)ail statt', a large
