38 REPORT OF NATIONAL MUSEUM, 1910. 
On account of lack of sufficient space, it has been impossible to 
accomplish much in the direction of separating and preparing the 
extensive reserve and unstudied collections, many of which have 
been stored for a long time in inconvenient places, preparatory to 
their removal to the new building. The corals not on exhibition have, 
however, been transferred. The dried sponges, which have been 
distributed in several places, were segregated on one of the galleries 
in the main Smithsonian hall, while another gallery was fitted up as a 
temporary laboratory for work on the extensive collection of crinoids. 
Through the temporary employment of several persons, more than 
the customary amount of routine work was accomplished. One such 
person of the grade of aid made considerable progress in the sorting 
of miscellaneous material. The others were engaged in recording 
and cataloguing, a work which, by force of circumstances, has fallen 
greatly in arrears and should be brought up to date as soon as possi- 
ble This was done during the year for the identified specimens of 
crustaceans, bryozoans, tunicates, and ophiurans. 
Through an oversight, the last report failed to make mention of 
the investigations conducted by the staff of this division during 
1908-9, which are therefore incorporated in the following summa- 
tion for the past year. Miss M. J. Rathbun, assistant curator, com- 
pleted her studies on the crabs collected in the Gulf of Siam by Dr. 
Th. Mortensen, of Copenhagen, and in the Indian Ocean by H. M. S. 
Sealark on the Percy Sladen Trust Expedition of 1905 under Mr. J. 
Stanley Gardiner. The report on the former is in course of publi- 
cation in the memoirs of the Royal Danish Academy of Sciences, while 
that on the latter will appear in the Transactions of the Linnean 
Society of London. Other investigations finished by Miss Rathbun are 
incorporated in a report on the decapod and stomatopod crustaceans 
of the coast and fresh waters of Peru, collected by Dr. R. E. Coker 
and submitted to the Museum by the Peruvian Government for 
working up, now being printed in the Proceedings of the National 
Museum; in a paper on a small collection of decapod crustaceans 
obtained by Mr. Thomas Barbour in the Dutch East Indies, British 
India, and Japan in 1906-7, to be published in the Bulletin of the 
Museum of Comparative Zoology; and in an account of the decapod, 
schizopod, and branchiopod crustaceans contained in the large 
collection of natural history secured by Mr. Owen Bryant during his 
Labrador trip of 1909, which will be published in the full report of 
the cruise. The localities for each species of the collection last men- 
tioned have already been given in a list of the crustaceans of Labra- 
dor, which forms an appendix to Dr. Grenfell’s recent book, entitled 
‘‘Labrador.”’ 
Mr. Austin H. Clark continued his researches on the crinoids, and 
has the first part of an extensive monograph of the group nearly
