crabs known from North and South America. She has also named 
the crabs of various current accessions, notably of large collections 
from California and Japan, including Formosa. Mr. Waldo L. 
Schmitt, curator of marine invertebrates, has had but little time 
left from routine duties for research work. ‘The first installment, or 
part, of a report on the Macrura and Anomura of the Australian 
Museum, collected by the “ndeavour, covering the families Peneidae, 
Campylonotidae, and Pandalidae, has been completed. The reports 
on the Macrura and Anomura of the American Museum Congo expe- 
dition and the Barbados-Antigua expedition of the University of 
Towa are still in progress. Mr. C. R. Shoemaker, assistant curator, 
has given much of his time to the working up of several large lots of 
Amphipods, which were sent to the Museum for identification. Sev- 
eral reports were completed and published as shown in the bibli- 
ography. Dr. Harriet Richardson Searle, collaborator, I am happy 
to report, has resumed her studies on the Isopoda and has recently 
completed a report on the collection of terrestrial isopods, secured 
by Dr. E. J. Jakobsen in Java. Mr. Harry K. Harring, custodian of 
rotatoria, has completed his report on the rotatoria of the Canadian 
Arctic expedition and the first part of a report on the rotifers of 
Wisconsin, which includes a revision of the Notommatid rotifers. 
Both of these papers are now in press. The second part of the report 
on Wisconsin rotifers is well under way. In addition, he has identi- 
fied a number of interesting collections. 
Dr. William H. Dall’s completed summary of the West Ameri- 
can collection from San Diego to the Polar Sea was published as 
Bulletin 112 of the United States National Museum. It includes 
the results of research and collections made by west-coast contrib- 
utors and the honorary curator since 1865, amounting to more than 
2,100 species and varieties. A number of interesting new, forms, 
including a second species of the peculiar South American Felipponea, 
were received and described during the year, as indicated in the bib- 
liographic list. Most of the time not occupied by routine matters 
has been given to a monograph of the marine shell-bearing mollusks 
of the Hawaiian Islands, based chiefly on the important collection 
donated by Mr. D. Thaanum, of Hilo, Hawaii, and on the fisheries 
steamer Albatross dredgings about the islands. This work is well ad- 
vanced and only certain troublesome and prolific groups of minute 
shells remain to be worked up of the material in hand. Mr, John 
B. Henderson, a regent of the Smithsonian Institution, has been en- 
gaged on a monograph of the Antillean land and fresh-water mol- 
lusks. <A list of the mollusks collected by the Barbados-Antigua ex- 
pedition of the State University of Iowa has been begun. Considerable 
time was devoted to the identification of east-coast mollusks sent in 
by correspondents. In the little remaining time he and the curator
