REPORT OF NATIONAL MUSEUM, 1890. 



annually for increasing the Museum collections by the purchase of small 

 collections of typical specimens that can not be obtained in any other 

 way. 



A detailed list of the accessions for the year will be found in section 

 V. Notices of the papers published by those connected with this de- 

 partment will be found in the bibliography, section iv of the report. 



The amount of material representing the collections was increased by 

 the addition of 1,229 specimens, embraciug 180 genera, 239 species, and 

 5 varieties. 



The catalogue numbers taken up during the year were from 18431 to 

 23842, both inclusive. 



The more important accessions received during the year are: 



No. 22580: This accession, from the British Museum, includes a number of very 

 beautiful specimens of trilobites, represented by 57 specimens, carrying 27 genera, 33 

 species, and 1 variety. It will be of service to students in comparing American 

 with European species and genera. 



No. 22730: This accession contains 66 specimens, giving 11 genera, 12 species, and 

 1 variety, from the Lower Cambrian ; but the principal interest is centered in the 45 

 genera, 72 species, and 2 varieties, as furnisbed by the 526 specimens from the Hudson 

 terrane of central New York, which have been placed on exhibition in the southeast 

 court. This collection is one of the most complete of any that is known to me from 

 this terrane in the State of New York, 



No. 22847: A valuable addition from the Hudson terrane (Maquoketa shale) of 

 Iowa. It includes 178 specimens, holding 19 genera, 25 species, and 1 variety, and 

 affords the means of comparison between the fauna of the Hudson terrane in New 

 York, Ohio, and Iowa. 



There are two other accessions that properly should be credited to 

 this year, but owing to the papers not having yet been completed in 

 relation to them, they will be included with those of the next fiscal year. 

 The material contained in them is from the Utica shale of central Few 

 York, and from the Eurypterus beds of the Water-lime formation of west- 

 ern New York.
